Finished Product - DC Conversion Lincoln 225 BuzzBox AC Welder Tombstone
HTML-код
- Опубликовано: 12 сен 2024
- Finally finished the DC conversion to my Lincon 225 AC "Buzzbox" "Tombstone" stick welder!
I listened to your suggestions!
Added a Choke (2, actually)
Added a large heatsink to the full wave bridge rectifier (400A)
Added DINSE connectors so I can select AC, DCEN (DC Electrode Negative), and DCEP (DC Electrode Positive)
Even added an amp gauge!

I love all the comments from people telling you how you should do your videos so we can see every angle, and exactly how you should do the mod. The funny part is... none of those “internexperts” are gonna crawl out of their recliner and make it past the refrigerator. The people who use their brains and hands for more than scrutinizing comments, received all the information they need from your awesome conversion. Excellent job homie!
haha, right on...that was funny tho
That stick welder still has a place in your arsenal- even more so now that you've got greater flexibility in electrode selection.
The big advantage stick has over mig (assuming you've got a generator that can output 220) is that wind can't blow your shielding gas away mid-bead when you're fixing something outside of the shop.
You did a really great job, btw.
Thank you! I agree about their usefulness. I actually already sold this one, but I've thought about getting another one but we'll see if I can find the right deal on one. Thanks for watching and commenting!
@@burningdinosaurs Just out of curiousity did you break even or take a loss on the old AC tombstone?
Love the music while you are working 2:07 - Reminds me of the 1970s Fat Albert cartoon, when the kids were in the junk yard building things from junk.
I did pretty much the same conversion a couple of years ago, minus the choke. Used a block of aluminum I had laying around for a heat sink. Used 4 gauge automotive battery cables to wire the rectifier and connect the Dinse Connecters. Mounted the rectifier in almost the same place you did. The ammeter is a nice feature. As far as the cost effectiveness, the AC/DC version of that machine is over $600 these days, and that conversion probably puts out higher amperage on DC than the factory Lincoln unit that peaks at 125 amps. Hang on that Lincoln, you may run in to situations where the stick welder is a better option on heavier material than the MIG welder. I built a pretty beefy cart to hold both my converted Lincoln Buzz Box and my Lincoln MIG Welder. I mounted an electric box on the cart and wired the Buzz Box in to it, with a 50' cord. The MIG Welder plugs in to the box so I can switch from the stick welder to the MIG welder or vice-versa.
Yeah, you're right, it's probably still cheaper than buying an AC/DC machine new. Sounds like a real nice setup! I actually already sold it, but, like you said, I'm considering getting another one and converting it as well for those times where a stick is better than a MIG. Thanks for watching and commenting!
I have the same welder and have been wanting to do this for a while. Thanks for posting.
If you already own the welder, it's totally worth it to convert! It welds so much better. Especially with the choke. Thanks for watching and commenting!
I just bought a ac only machine for $50 this seems like a great way to up great a cheap welder
I had no idea what you were talking about, but AC/DC is one of my favorites bands 🤷🏼♀️😂
Haa! Well, a good running welder can produce some good music to my ears, but hopefully no screaming like Angus Young! Thanks for watching and commenting!
Lot more science in welding than most people realise !
Great modifcation to that great little Lincoln Tombstone AC welder! I like the red dinse sockets, I bought some new sockets here in the UK but we can only get black ones? I guarantee if you sell that welder you will regret it. The Miller Mig is great and it might do stick too, but you still need to keep the Tombstone. You cannot have too many welders. I have four and use them all in turn for different jobs.
I have a 1984 Oxford AC Oil Cooled 180amp stick welder, it has a battery charger built into it must have a DC output? I am pondering on if I could convert it to weld DC? It wieghs about 160lbs (80kg?) and isn't easy to shift about. Not as cool as your Tombstone but will do for me along with my more modern 2004 Oerlikon (now part of Lincoln Electric) 140amp DC Inverter welder.
I will give you a tip, welders are better than a wife, they never argue back, don't need much maintenance, always contribute to earning a living and you can live with more than one in the same house! Top regards from England!
Haa!!! Great tip lol!!! I hear ya on keeping the Lincoln - now that I've done all that work to it, I really want to keep it, but I don't really have the budget to keep both, but we'll see! That battery charger might be a separate winding on your stick welder, but I'm not really sure. I'd have to look up information on it.
Your heavy, square Oxford should be good to convert to DC. what can go wrong ? at most, damage to the bridge rectifier would happen.
hell, give it a try, only take a half hour or so. done my ancient lincoln 225 one, cut the cables about 2 feet from box, done up bridge rectifier, 28 uFarad 250 volt capacitr, and welds just FINE. holds arc good. now, just have to install all in box, and fan it. STAY AWAY FROM THE BATTERY CHARGER CIRCUIT, as it has a separate dc rectifier in it. good luck.
Most important tips ever!
@@dwightlee6164 Thanks! Another tip for you.
Always remember that women are like wheelbarrows, they can be hard to push, don't like reversing and are easily upset!
I did a conversion to my small gas Lincoln welder , power supply, years ago before Utube. I know it's too late now but you should have purchased the lincoln 3 way switch which would give you + -, -+, or AC instead of moving around the leads.
That's a great idea! I wish I would have thought of that back when I did this one too! Thanks for watching and commenting!
You and I think alot alike when it comes to money. Thanks for your time and video
You might be able to put a capacitor across your current meter so it will slowly allow the indicator arrow to dissipate.
Wow its the best tombstone modification i've seen yet on RUclips also the most esthetic looks better than other with who have use the easy route of installing the bridge rectifiers outside with non protected for electrical shorts open air connectors to get kids zap by ,yours looks much more secure ! You treated this old machine with respect for the use you had with it before by giving it a new life extension instead of sending it to the landfill ! Even with a mig its god to keep a stick welder because welding outside in the open air make your shielding gas useless a stick is still more than adequate check all the pro welder outfits still using stick for outside work !
Thank you! I appreciate that! I did, actually, already sell this one, but I may end up with another stick welding option soon. Yeah, I really didn't like the idea of mounting the rectifier on the outside, nor the choke, for most of what I do, I prefer the "sleeper" look, or at least as factory-looking as I can manage. Thanks for watching and commenting!
Uncle Tony says excellent work ,, you & him seem to have the same time frame for personal projects - LONG - life gets in the way - good research & execution on final product 👍🏻🔧😎
For sure!! When you've got 100 irons in the fire, they take a while to forge through! But, 1 checked off the list now! Thanks for watching and commenting!
good idea to blow lincoln crackerbox out once in a while my fan did not come on once, opened it up thinking motor was gone, but mud dobber had built nest between housing and fan blade mine is 1975 model and still going strong good vid THANX!
Great show Dino. I like your video and the way you present it. Your wife is going to love you for tarring apart the micro-wave. Bon travail félicitation.
Now days you can buy ac rods in 7018, mg 500 which is a good burning rod, and a rod called 930. All burn very good on ac and have good tensile strength.
Would you recommend using ac 7018 rods on a trailer perhaps thank you.
Only two min in and you've got a fan, good vid so far
Thank you! And thanks for watching and commenting!
that welder built America you can pass that on
Great subject Sir 😉 You have a great sence of humor 👍😉 and you are a strong man with a strong back Sir 👌 You have a great little helper 👍 What you use your Miller to modify your Lincoln Electric 🤣 You are a great electric inventor fabricator Sir 👍 You should keep you modify buzz box, when you will have a rusty contaminated steel it'is much easier to weld with SMAW ( stick rod ) than a GMAW ( mig ). Great video Sir Cheers !!!
I really would like to keep it, but I don't think the budget allows for both. Might keep some flux core wire around for unclean material or windy conditions, but I'm really not that good at stick welding anyway, so wire is a better option for me I could actually do stick welding with the Miller, if I change out the lead for a rod holder.. I guess that's an option too. Thanks for watching and commenting!!
@@burningdinosaurs If you were not living that fare i would buy your welding 😊👍 Cheers !!!
Now, the real question is, will it burn a 5/32 6010 smooth? If it were mine the next project would be to build a high frequency box to set on top so you could tig aluminum. It's not that hard with scrounged parts, and online plans. I aplaud good ol' fashion american ingenuity. My grandpa always told me, " do the best you can, with what you got, where you at". He lived through the depression, 2 world wars, and passed in 1983, he knew and things most folks with a phd just can't understand, lol. God bless. Watch after that lil' feller, and teach him good. 😃
Thank you! It welds 6010 fairly OK. Not perfect, but I burnt through a few pounds with it before I sold the welder. I'm very much of the "work with what you got" mentality! I agree: experience is almost always a better teacher than a classroom! Thanks for watching and commenting!
Dude, you are a fucking hero. That is bad ass, the story you told about how you got the buzz box and why you did what you did to it.. i woulda kept the ol girl tho. But hellyeah, wire fed til im dead.
You sure got a lot of suggestions! Hopefully no one told to you put that Lincoln where the sun doesn't shine! Lol
Well, similar-ish lol! You know how youtubes are lol! Thanks for watching and commenting!
Good job
Great job on getting what you want with the resources you have. That was lots of work. My only suggestion is you keep the stick welder. MIG is great but it has its limitations. Stick just gives you another option. If your like me, the day after you sell it you will need it
the wire welder is a very nice and much easier to use than a stick welder, but with the DC option you now have I think you should use it some before you push the Lincoln off to the side. nice job on understanding how to change AC to DC at the high current level.
Yeah, I'm really not great at stick welding, so wire is a much better option for me. I'd love to keep both, but the budget its telling me to sell one or the other, and, even though I just put all this work into the Lincoln, the Miller is what's best for me I'm pretty sure. Thanks for watching and commenting!
BurningDinosaurs nice thing about stick is you can buy a small batch of specialty rods for different base metals instead of a whole roll of wire and different gas mixes. You can get a rod into place a wire feed won’t reach. Having both is definitely a big plus.
Be sure to turn off your gas bottle when you are done, small leaks can get expensive.
Awesome work man😁. I like the video style. Thanks for sharing
Thank you, sir! I appreciate you stopping by! Thanks for watching and commenting!
Thank you ! We appreciate your effort and time
Pretty cool, I need to convert my Lincoln 250 to dc.
Thanks, Frank! Yeah, you could probably do a very similar setup as I did. That bridge rectifier was "rated" for 400A, I'm sure I'm pushing it at 120ish right now, but 4 good quality individual diodes might handle better (better heat dissipation) (that's what is usually in DC machines). Thanks for watching and commenting!
Nice job man! That's an amazing success.
You should mount that gauge in your mask so it’s useful.
Very nice! Now that you have DC you can also use it for TIG with an adapter and TIG torch and Argon bottle. That's my end goal for my AC welder.
for my conversion, I just wrapped one lead wire around a one-inch bar of steel works good
Yeah, anything magnetic really should work. The microwave transformer makes a nice little package tho, and I believe there's something to the laminated design that mitigates hysteresis? Not sure on all the technical details, but it's what was recommended, so I went with that. Thanks for watching and commenting!
I got a tombstone ac for free awhile back I’m gonna do this to. Do I need it? No. I have 110 and 220 machines set up flux core and mig as well as a sa250 black face that I do mobile on. There are times it’s just easier to glue things together with different tools. People who know will not criticize you for modifying your machine. The intersnobs w that say just buy this or that are the ones who would be lost if board goes down in one of their machines like happened on one of my engine drives in the past. That’s why I now make sure I keep old school machines around.
we buy what suits our needs and budget at the time. i dont have a arc welder. i dont know the first thing about arc welding. or mig for that matter! i use a miller 240 volt mig. it works fine. looking to upgrade to a bigger one now. seems like the projects just keep getting bigger with thicker steel.
Yep, you got that right! Stick welding definitely takes more finesse and attention to detail to do it right, which I don't have either lol! So, wire is definitely a better option for me. Yeah, you're projects definitely are getting bigger all the time! Thanks for watching and commenting!
Thanks for the video. I do the same thing with my projects; make do with what I have based on investment/return.
I would, however, not get rid of that stick welder. You'l always go back to it. MIG takes less skill and is faster production, generally, but it costs more to run and is pickier as to what it welds well.
If you own the gas bottle, you have to keep it filled and certified. The gauges on the tank get busted. The roll of filler wire is not cheap and needs to be kept clean and rust free between projects or it mucks up the feeder, lead and gun. The leader and gun are fragile and eventually wear out at several failure points, almost never at the same time.
For casual home or occasional use, stick is still the way to go, IMO.
Thanks for the vid and making it through the project. You appear to be open to suggestions. Awesome. Here is a suggestion that would help many, including myself and put some money in your pocket. If, in the video description, you placed affiliate-links, to each of the parts you used, through Amazon, ebay or some other vendors, in the description, then the rest of us, who are wanting to do the same conversion to our welders, could click on the link, go directly to the site/page you used as your source, so we can purchase the exact same parts you used from the same vendors. This would be is a huge help for the rest of us having to hunt down these same parts and making sure they are the correct part. Which as you know takes lots of time. You have already done this work of hunting down these parts, so why not make some extra cash from this work by placing these affiliate-links in your video description? Thanks.
PS: I'll be keeping an eye out for these links and will probably be your first buyer. Thanks.
Yes, please do this
Great job on the build. Can you list the products you used.
LOL! This guys great… subscribed
Your little boy. Teach him well! Those holes are 1 3/6" holes with a carbide cutter.
What'd you wind up using for chokes? What did you use to rewind if you did and how many winds? Great job! Looking forward to doing similar more in the future with my buzzboxes and maybe more. Great upgrade and repurpose/hack/mod. Guessing you saw the Hackday article regarding and if not, consider maybe further upgrading... though sounds like you're not planning on keeping. I just got a Century 125GL... though plan to keep one of the buzzboxes at least where one is going to be the grill for a fully functional hybrid garden tractor engine welder/generator and more. Thinking the 20th Century one.
I used a Microwave transformer as well as a torrid I ordered from Amazon. I went through the torrid about 3 turns and the transformer about 4 or 5 turns. It worked really well, but I've already sold it and got a wire welder. I'm just not good enough stick welding to keep one around. Might get another some day if I find a deal on it. Thanks for watching and commenting!
Great video and conversion, could you give me a list of all the parts or links to them? I've had one of these old Lincoln's for a long time and would really like to do this to mine. Thanks in advance.
Yeah, I can add some details to the video description. Give me a little while to find them.
Where is the list of parts? Great vid!!!
Nice little MIG!!!
Run mixed gas for a pretty weld..
Or straight CO2 for good penetration... We ran straight.. it's getting harder and harder to find here..
Yeah! It came with an almost full tank of C25, 3/4 of a small spool of .023 wire, and the tank was on a separate 2-wheel dolly. All in all, a pretty good bargan for what I paid! Should come in pretty handy! Thanks for watching, Ed! Hope all is well with you all, I'm not doing a very good job of keeping up on the youtubes lately, but I'll go catch up one of these days!
@@burningdinosaurs nice!!
Ya, catching up on Videos lol 😂
All good. I can't keep up with everyone, but I try 👍😎
Nice job on the conversion.
Thanks, Scruffy! Thanks for watching and commenting!
thanks a lot for explanation
That's a real man cave you've got.......I bet you freeze your balls off in winter, as for Summer....some like it hot and dry, Melbourne's 35 dec C down in OZ is my liking and we're heading for the hot stuff now.
Thanks! Yes sir! Although I'm working on putting some Styrofoam insulation I picked up cheap at an auction, it helps, but it can get down to -10ºF (-23ºC) or lower here, and it's pretty hard to keep the old corn-crib-shop warm no matter what then. I'm same way, though, I'd rather have heat than cold, but 95ºF (35ºC) can be oppressive too. But stuff has to get done, so we just carry on! Thanks for stopping back!
Agreed! Most things just look "dead" in winter. It's harder to get around and more dangerous when the roads and sidewalks are frozen. Too much night time and not enough daylight. We also have to wear twice as many clothes making it harder to move around. Just not a convenient time of year.. I really don't like winter at all either. One will never hear me complain about hot weather but I cry like a baby when it gets cold!
i learned the 3 r's policy one is reutilize , buy a new one means use more raw materials and energy and so on
Excellent point! I am definitely one who would rather work with what I have than buy new, for that and many other reasons! Thanks for watching and commenting!
I would have added some heat sink compound between the rectifier and heatsink to aid in the transfer of heat.
Cool feature with the ampmeter, but where did it actually connect to?
It uses coil that clamps around the cable. I put it on one of the AC wires just off the transformer. I probably should have explained that better. I may make another video explaining more details about the conversion. Thanks for watching and commenting!
Shoot, with the price of the original welder, work, and the add-ons, you are still cheaper than buying an ac/dc rig from the store. I want to say they are about double the price.
Edit: heck of a job also.
they practically give away used ones...
I'm not understanding the choke for for welder, how do you hook it up?, run your wires with it? Absolutely a great video! I'm doing the same with mine. Got the rectifier and heatsink. I have an old microwave not working in my shop to use for the choke.
You got my vote brother LMFAO I felt that intro fa reealz
Now u got DC rig up a tig torch with a old mig welder drive for scratch arc tip tig
Success, how did you ever get by without comments. lol
I have no idea!! LOL!! Most are good, some are funny, some... not so much lol! Thanks for watching and commenting! Really! I mean it lol!
COOL!!!
I can muddle through some stuff, but never got into all the diodes, rectifiers, and such...
When I need that stuff done, I have friends 👍😎
excellent video , me being me i would wrap the sheet metal or bust out some money for some duplicolor chrome cast paint to pimp it out ,or glitter paint just me
haa! Yeah you would lol! It's really not a bad idea if I were going to keep it, but not sure it would be for everyone if I try to sell it. Then again, maybe it would!
you scared me when you lifted the welder on to the bench, You did not blow out a nut or your back, Whew!!
LOL! They're not light by any means! That's pretty much why I left it on the floor last time, although it was easier working on it up on the table! Thanks for watching and commenting!
Great video. Ill be doing mine next month. Who was the music from please.
I’m confused, why did the red connector above the ammeter become black? And could you share a common negative between ac and dc?
Great video! I’m going to pull out my tombstone and take a good look at it
Thank you! Not sure if I had the connector in the wrong place during the video or not, I know I really had to figure out how to fit everything in there without any issues. With a full-wave bridge rectifier, the output is basically turned to 120hz pulsed DC, if you shared a common leg, you could only have a half-wave rectifier, which would result in 60hz pulsed DC at only 50% cycle time, basically instead of flipping the polarity around every time, it just doesn't allow half of the current to pass. It would probably still weld, and with the properly sized choke would probably still do a good job, but with the full-wave rectifier it should end up smoother, but requires separate leads for AC and DC.
I do have a project I want to weld with this stick welder before I sell it, maybe I can do a little more explanation on that video.
Thanks for watching and commenting!
Gotcha. Thanks for the reply.
I like how he makes fun of all the "suggestions" in a casual way. He's like thanks for all the comments about what I should of done on a test video, that was only to see if it would work or not. Lmao.
Congratulation on your conversion. Unfortunately, all I saw was you working on the box. No close-up pictures of what you did or wiring diagrams or discussion on what got wired to what. Would be nice to add those items on a DIY video so other could benefit.
Where did you find that big heatsink?
It came from an old stereo amplifier that was junk. I think you can find them cheap online too, if you're not too picky about them, but junk audio electronics are always good places to find things like that too. Thanks for watching and commenting!
I just bought an old Buzz Box because my Miller 211 burned out and put me out of work. Keep Your Buzz Box. Im buying a ESAB when I go back to wire feed. Got any links to the parts you used?
I got both the rectifier and the DINSE connectors on ebay. The number change all the time on there, but the rectifier was 400A 1000V, and the DINSE are just cheap ones I found on ebay. I actually already sold the Lincoln, and, I agree, it's very useful as a DC stick welder, but I may have another trick up my sleeve if the need arises again! Thanks for watching and commenting!
I like the tombstone ac machine with 6011, most versitile.
What did you end up with on the choke? What size wire and how many turns through the steel core? Did you pass all the DC current through it?
I used both the microwave transformer core, as well as the ferrite torrid I bought online. I think it was about 7 turns through the microwave transformer core, and about 3 through the ferrite torrid. Only the positive lead goes through the chokes, and, yes, all DC will pass through them. It does work pretty well, I welded for about 4 hours with it this past weekend and it's pretty smooth! Thanks for watching and commenting!
@@burningdinosaurs just to get some more understand since I plan to do what you did in the video, you just ran the positive dc cable from the recrifier through the torrid and the MOT then right to the dinse connector? It's just kind of hard to see in the video and you can definitely see how nicely the dc side of your welder runs and I'd like to replicate this. And did you re-weld the I part of the MOT back to the E part?
@@sl33ksnypr285652 That's correct. I really did a horrible job explaining and showing what all was done, sorry about that. But, yes, that's how it went. And, yes, I welded the core back on the transformer with my other welder. I probably should add a voice-over to the whole video to explain what I'm doing. Not sure if I can at this point though. Feel free to hit me up with any other questions!
@@burningdinosaurs okay cool thanks for the info! I'll update you when I decide to do this stuff to my welder.
Dc the lower side im thinking n hey i was raised up n shown how to weld with the red tombstone welder
Very easy welder to lift onto a high surface, yessir, definitely doesn't weigh over 100 pounds.
Where did u get your welding cable that you u wrapped in the microwave transformer.?
I already had it, but you can usually find it online or at a welding shop. It actually doesn't need to be the fine-strand welding cable, it can be more like THHN normally used in interior wiring since it shouldn't move around a lot, but just be sure it's well-insulated. Thanks for watching and commenting!
Great job! Can you send the link where you bought the Amp Gauge? Thanks.
Would have been great to see what you did no help at all
How big is the toroid core ??
have same welder. ordering parts online to do this and no where near as electrically savvy as you but goin for it, would like to start tiggin. Is the microwave transformer necessary, if so what was it connected to? couldn't get a good look and have a bad understanding of it even after a few vids on it. would just adding rectifier with heatsink cause me problems or will it work fine?
I admit I didn't do a great job explaining how everything goes together. Basically I'm using the microwave transformer core. I wrapped a length of welding cable around the core, then welded it back together. I put mine on the positive lead, but it really doesn't matter much. It functions as a "choke" and basically smooths out the current. If you also wanted to smooth out the voltage, you'd add a large capacitor across the positive and negative output of the bridge rectifier. My first video on this conversion was simply installing the full wave bridge rectifier, and honestly it worked fine, just not as smooth, and the finish and spatter was noticeable. But if you find an old microwave out on the curb somewhere, I'd suggest picking it up and pulling the transformer out so you can wind a choke, it really does help.
Exactly what I wanted to know, great job!
Could u tig weld with that conversion ?
I liked your video. Your conversation is very good. Go down town and buy you an AC DC Lincoln toomstone. You will pay appx. $800.
Thank you! Yeah, they're pretty proud of them machines. But knowing a cheap conversion is available if you already own one of these machines was very helpful for me. Thanks for watching and commenting!
Could you set it up to tig
Sure! There are adapters out there that allow you to hook a hose and lead to a TIG torch lead, with the AC and DC option, you could TIG lots of different materials, however, 60hz (Standard North American frequency) 50% positive/negative is not super common for welding Aluminum, or most other materials you weld in AC, but it can be done!
You need to have high frequency AC current to stabilize the arc for aluminum welding but there is no reason you could not weld steel with DC current
After converting from AC to DC does that mean you could run it on 120v power?
No, the box still requires the 220V input. Only difference is now it can run both AC and DC welding rods.
@@burningdinosaurs Ah I see. Thanks!
Its still cheaper this way than buying and AC/DC machine from any trusted brand.
6:24 ??/ whats with jimmi hendrix noise....??//// well, at least you know how to be usefull.......good for you, happy burnin'. you may consider adding a 100 u Farad 250 volt capacitor, across the + and -- side of the bridge. This will add a bit of voltage (smooths out rippley DC), and, WILL HOLD AN ARC MUCH BETTER.....explosive arc, will be ok.
I thought about adding a capacitor, but then I'd also want a discharge resistor across it as well, and I just didn't end up trying to figure one out. I'm sure it does help. I already sold this welder, however, but may pick another one up and do the conversion again someday if I find a deal on one. Thanks for watching and commenting!
HOW ABOUT SOME SAFETY GLASSES?
How did you make the choke?
Where did u get amp meter at?
Is this ac rod or dc rod?
*Opens box of welding sticks*
smells like dc rod
Nothing like the smell of 7018 in the morning!
BurningDinosaurs try 7024 you can weld with that without even trying.
You didn't show how the wires were normal nor how you rewired. I'm still in same boat. I don't want to take it apart until I know how it's wired.
True, I should have overlayed a schematic. The way I did it, was the original wires going to the leads (stinger and workpiece clamp), I tied to the 2 middle black DENSE connectors. Then from tied in with those, it goes to the bridge rectifier, it's AC, so it doesn't matter polarity. From the rectifier, the positive I ran through the chokes (about 3 turns on the torrid and about 5 or 6 on the microwave transformer core), then to the red DENSE connector. The negative from the rectifier went to the black DENSE connector. I also, though unnecessary, added an amp gauge that clamps around the wire on the AC side, again, polarity doesn't matter there. That's pretty much it. Hope this helps! Thanks for watching and commenting!
I guess he must like sun burn; welding in short sleeves.
great video! I have few questions though, so now you have the welder being capable to do AC and DC in around 200 ish amps on both currents? The stock Lincoln buzz box AC/DC can only do 125 amp in DC current
Please, make an in depth video!!
I will try to get something put together sometime. I've actually sold the welder, but I can give more details in another video and I've got a bunch of welding video I can add in. Thanks for watching and commenting!
Yes! This is by far the best example of a DC conversion on tombstone. Unfortunately I don't have enough electrical sense to put something together like that without all the connections spelled out for me. Very inspiring!
Cool video but seems like a lot more than just $30 involved lol
Yeah, I think the bridge rectifiers have gone up since I bought it almost 2 years ago now. But at the end I go over what my total cost for the conversion was, and if it ends up cost-effective or not, and for some cases it is and for others it isn't. But showing how it can be done might save some people some money, so hopefully it can help some out. Thanks for watching and commenting!
I was hoping you'd show where and how you mounted everything on the inside of the welder.... Oh well....
A real pity he does not move the camera so WE CAN SEE what he's looking at/working on!
No capacitor......
No. I really thought about it, but many others were converted without the capacitor and work well, as did this one. It could probably be added, but it's sold now and the new owner is very happy with it. Thanks for watching and commenting!
