HA - I am watching this again almost three years to the day and another year so damn close to Christmas (2022). CHEERS from AUSTRALIA.
Thanks for watching 🤩
Definitely learn a lot from this video.
The straightening of mig wire was amazing.
love the twist the wire with drill trick! I learn something new...Thank you! and as always, great video.
hi Trev thankyou so much got a AC/DC welder second hand but nearly new no instructions bought the extra small torch and all the extra bits spent far to much , done mig and stick before found it so hard from my set up watched all the tig vids, yours is the first to explain upslope and downslope, and setting and suddenly light bulb moment set up off and running, the welder hasn't been used for 18 mouths, now just at the right time found your channel thanks for your explanation really helpful
That’s brilliant! This makes making theses videos worth it thank you 😊
Trev with out any doubt your welding videos on welding thin car panels or sheet steel are the most helpful and practical on utube. I'm trying to teach myself to weld old Citroen panels which fo down to 0.55mm and it is fine on the welding table but being able to do it on the car is a different story. Thanks.
I've had this mig welder for 3 years now and it is fantastic.
You are a humble craftsman. Thank you for all your informative and entertaining videos.
23:05 text flashes for less than second saying "Cleaner start than before" for whoever is curious as I was ;-)
G'day Trev! Many thanks for this video. I've come across lots of discussion of gas lenses but never really understood them. Now I do because you took the time to explain the basics and show how they're installed. Great! Now I'm also on the lookout for a lightweight tig torch so that I'm not wrestling and welding at the same time. Keep up the great work.
Great tip for straight wire, great tutorial. I love the montage of repairs at the end too. Proper skills.
Im sticking (pun intended) with my chinese ct312. When people look at my crappy welds and ask why i dont weld like our Trev i can just blame the welder and say its cos i cant afford an R-tech. :)
Great video. I look forward to learning more about tig welding and other skills you will teach us. Thanks.
Fantastic information. Twisting the mig wire was inspired - can't wait to try that little trick.
I'm learning lots so please keep the videos coming.
Thanks for the tips. I normally thread the wire inside my sleeves and around the back of the apron.
Good morning Trev, that mig wire trick and welding technique is invaluable information. Thanks for the welding technique and expertise. You take care and good luck.
You are an excellent teacher.
Keep em coming Trev... Cheers, Doug
Making your own 1/16 welding rods from mig wire - love it ! top tip
Thanks Trev for keeping it simple with your info. Sometimes too much technical information tends to hinder my interest not help.
Really helpful! Just starting on my Tig adventure and first. Hour was a nightmare... this helped lots
Thanks again Trev , very helpful video keep um coming mate 👍👍
Really learning a lot from your videos, thanks.
Great info. Keep the great videos Trev.
Love the new tricks. Never thought of using mig wire for tig welding.
This dudes hair is absolutely glorious!!! Great video bro, stay classy!
thank you very much for passing on the tip about twisting the mig wire for filler, and you may have sold me on trying tig, (probably a cheap one off ebay) I'm having a tough time practicing 22 gauge welding with a cheap flux core welder and / or my gas welder but now I'm gonna try the mig wire with gas as filler. Never stop trying...
Your awesome Trev
Big fan!!
These are always the best explanations.
Thanks Trev. Great video ! Watching (and learning) from New Zealand.
Cheers ! : )
love the wire trick mate .....this Old Arse is still learning ....good on ya .
Learnt a lot trev although I don't think I will ever buy a tig or do it but I still learnt a lot!!!!
Another great video. Thank you.
Great tip for the mig wire hack Trev. those CK torches are awesome especially fitted out with a lens kit..great gas coverage. thanks for sharing :)
Another great video thank you
Great Vid, thanks Trev.
Thanks great video, verry helpful.
Great stuff Trev. I aspire to fab that well one day. Definitely checking out the baking van.
thanks mate, great video
Class Trev, I’ve just purchased this welder from RTECH and I’m struggling to get to grips with it tbh, I’ve been using mig for years but tig is a whole new ballgame ..... Cheers Trev 👍
Hello all. Have a nice day. CHEERS from AUSTRALIA. Start of what is another week getting so damn close to Christmas - again.
I suppose it will be sunny down there for Christmas -but we are gonna have a good one cos I heard we're having a National erection .........................................
Thank you.
good stuff, thanks!
Another great video Trev, some good tips, if only it was as easy as you make it look 😎
Awesome 👍🏾👍🏾
Great tip about using MIG wire Trev. I did find when using filler rod the welds were a bit heavier than I would like. But did pick up on the bead zapping into the weld & just laid the rod along the seam pushing it in & out of the arc like you demonstrated. I just wish you'd been around doing this stuff years ago mate.
Tony Dalton I don’t find this a natural process but I am getting better (learning on the job) I agree that it’s a hard job not applying too much filler especially on the guillotine cut metal as it actually didn’t need any! Cheers Trev 👍
Hey Trev, I tried welding in a patch panel first time today, sadly I found your vid after I welded.
I struggled a lot figuring out the technique and after lots of trial and error I came up with almost the exact same setup, angles, everything like yours ha ha. Sure wish I’d have found your vid few days ago, would have saved immense frustration.
I find the pulse IMMENSELY helpful, especially vertical panels, helps the puddle freeze and stick, and helps a lot with burning through.
Onwards and upwards from now on 👍
Hello Trev , your look like Perfekt men !
Nice work....
Learning lots
Awesome tips!!
+ 1 sub.
Thank you.
Great advice. I attempted to butt weld with a MIG on my Tacoma bed. It was great till I tried to fill in gaps. Warped it. Need to save up for a tig it seems.
First class as usual
doubleboost thanks John 👍
I just realized that I've been lagging behind your progress, watching you'r old stuff, thinking they where the newest videoes. I got used to using 2.4 tungsten at work, but I've picked up 1.6 that I use when welding sheets. Don't matter that much, but a 2.4 holds up better when dipping, but noone ever does that, right :P Think having a good grind on the tip is more important, and needle is nice, but I've learned to knock the tip off, because it melts away, and ends up in the pool, contaminating the weld with unsimilar metals. At lover amps, seems like you'll get a better weld if you like leave a needle on there, but like half a mm will like disapear after some use. Think I'll try to pick up a torch like that. I got a few of the 5£ ones on ebay, and haven't smoked one yet, but I know the CK ones have better insides, and will probebly last for ages.
Nice video. Mahalo for sharing! : )
Great video as usual Trev. Great welding advice and tips too ! I am still learning mig welding lol so thats out of my league.
Cheers, Jeff.
cabdriveruk Jeff I got by for years using just a mig welder but if you want to take the joints to the next level then mastering the TIG is the way to go, I’ve still got much to learn myself. Cheers Trev 👍
@@trevsblog Its just finding the time Trev these days.
cabdriveruk you’re not kidding, finding time seems to be getting harder and harder. Cheers Trev
Best Ive seen...
Got a Kemppi minarc 180 for $400 in New Zealand, my 20year old son and I are going to have a ball when it arrives, he’s got hundreds of hours on Tig now, going to be a great excuse to spend some time on the HQ Statesman together and his Chrysler Avenger
Get your self some wedge colets so much better than the standard ones.
On thin aluminium under 2mm I will use a 1.6 tungsten
Great blog, Trev! Very timely for me. I'm stitching my rusty old '73 Super Beetle back together and your videos have really helped me understand my new TIG machine. Keep 'em coming! Cheers!
Great stuff Trev. Tig is definitely the way to go for sheet body steel . Even at the early stages of learning I am now joining metal rather than butchering it into a shambolic mess. Sticking to red tungsten until I get better at it and then I will try the blue. Also using filler rods as I have a flux core welder not a proper mig ( I guess I could use the wire and drag the slag but why spoil a gas weld ?) . Late in life skills learning has much to recommend it !
The blue works the same. The only reason not to use the red is it's a tiny bit radioactive which would be a problem if you got some of dust from sharpening it into your lungs. I don't think it's a big risk but might as well just get the blue.
Trev great info and I enjoy ur content. You might check your argon purity the discoloration on your tungsten looks worse than it should be considering how little amperage you were using. I just resolved a bad bottle and my tungsten was looking the same. Worked fine on DC steel etc or at least it was not as noticeable but it made aluminum unweldable. Keep up the great work!
Michael Hansen my dwell was a little slow, I’ve only welded the three inches of steel you saw in the video since using the new torch, with a bit of practice I’m sure things will improve. Cheers Trev 👍
Greeting from sunny Queensland. Great series on the tig machines Trev. I just bought myself a flexible head which should make things a bit easier plus I have some chinese gas lenses that I will use also. Just wondering if the new small torch that you got is still compatible with the 2t 4t setup. Thanks again for your contribution to helping us old fella's out
"Like my hair" cracked me up !
Fab job. LOVE that twisted wire trick!! Wow, so simple so easy and obvious once you think about it. Thanks BTW what is your preferred method for sharping tips. There are endless ways that are "the only way" Just wondering. Thanks
You can also twist 2 wires (or one bent) together. 2*0.8 is equivalent to 1.1mm and 2*0.6 is equivalent to 0.85mm.
Rtech sell low alloy 1mm mild steel tig filler wire BTW . 😉.. I used to use mig wire twist trick till I found it.. It was few years back so Cant remember for sure but think it leaves a softer weld.. Think sombdy told me once mig wire is higher tensile alloy to cope with the wire feed process 🤷👍😹😹
Good point , there's a couple of flavours of filler rod for m/s -you can also use stainless filler on m/s -and of course there's phos/bro brazing filler . Could be wrong -but think the different flavours for m/s might be to do with how the work is to be finished -ie galvanised or not ?????? tbh , you can probably use a coathanger as filler if the jobs not critical -but then you'll get earache from SWMBO LOL.
Wow I want a tig now the wife is going mental hahahahaha I wouldn’t want to be you if she ever gets her hands on you trev lol fantastic video as always keep up the great work
😂 with you mate
I have used TIG on auto sheet metal, but finally gave up and settled on MIG. Why? Because TIG welding thin sheet requires 100% perfect fitup or you will have all sorts of problems...at least at my skill level you will, anyway. Getting perfect fitment on sheet metal butt-joints is very time consuming and sometimes nearly impossible.
MIG, on the other hand, actually goes better when there is a slight gap between panels. So for a hack like me, MIG turned out to be the answer.
John Shaft believe me John I know where you’re coming from, I’ve had two friends give up also. It’s one of those processes that doesn’t come naturally but bridging the gap gets easier once you have that understanding breakthrough. You can still do good work using just a mig. Cheers Trev 👍
Perhaps I missed how to sharpen the tungsten tip in a previous episode. I'd so love to see how to cut out a patch and let in a repair. Many thanks
Alex Wild no worries I’ll show this in an upcoming video. Cheers Trev 👍
I’m hoping you will protect what’s left of your eyesight. Important for welding!
I just give the wire a quick pull with the slide hammer and it does the same thing. As to TIG welding auto body, easy enough to fab new parts on the bench with new tin, but seldom can I get the backside of a weld seam clean and rust free enough for TIG when it is on the car. Certainly possible do do the job, but very slow and with a lot of blowout repairs required. If you have any videos that deal with this reality, would love to watch them.
In general I find that most people just make a repair section that just covers the rusted area. A few years ago I got frustrated blowing holes in thinned metal and started to make my repair sections far larger taking them back to good metal. I have found that although the work involved is initially more the results and satisfaction without the frustration is better. Cheers Trev 👍
Trev, if you're having trouble seeing the end of the tungsten to sharpen it then maybe a set of magnifiers is in order. I use what the weld supply store calls a magnifying lens {available in various powers: I use a 2 cause I'm old} mounted inside my helmet to sharpen up the weld pool. It's night and day as far as being able to see what you're welding: if you can't see it you can't weld it.
john devries I wear reading glasses but I hate having to wear them as I cannot see anything when I take them off. The perils of getting older... 🧐
@@trevsblog Trev, the lens mounts directly into the helmet, most helmets have little clips to hold them on the inside surface of the self darkening lens. They work really nice because you're not constantly taking your glasses off and on. Try one of the same magnification as your reading glasses, you'll like it.
Thanks Trev, for the simple and practical demo. I will go and but a smaller torch, as I have a 200 amp one which came with my Unitig 200.. I have also been advised to do this by my good mate, whom is a sheet metal fabricator. Having arthritis, he says it will be much, much easier for me to use
B. Curtis a lighter torch is easier to use for sure but you can still weld with the standard torch. Cheers Trev 👍
Great vid Trev, will you be at the classic car show on Friday the 8th
Robert Mallett sorry bud I’ll be there on the 9th... 👍
Top stuff -real world welding - good info on the application of the filler - adding filler was ( still is) the trickiest bit for me until I twigged that you only just dab the filler in on the leading edge of the pool - I was stuffing it in too far and often stubbed the tungsten . Re watching the youtube superwelders , bear in mind its usually their day job and always take into account the material thickness they are welding -the stuff Trev is welding is always challenging , so maybe start out on some thicker stuff , and don't get downhearted if your efforts on the thin stuff don't come out as "weld porn" .
Jaques Daniels the guillotine cut metal really needed no filler so any I added was going to be excess. I’m never going to be a TIG expert and to be honest I don’t need to be, I can make a seamless joint and I know it’s strong etc and that’s good enough what I need to be doing or anyone else that’s doing joints on car bodywork. You’re right about the superwelders it’s great to watch but a bit of a pointless cross reference for thin steel which I believe skews perception of what we’re try to achieve, none of the hand built cars I work on have flawless welds, they’re all undercut and very obvious. Cheers Trev 👍
Great videos enjoying them very much.
My question is how to manage body panels that have pitted rust? I have cleaned it as much as I can however the pitting is still there. I can not afford to grind them out. The panels are too thin. It is no problem using a MIG so why would people use a TIG on car panels? Can you shed some light on this? Is there a setting on the TIG to help with this? Thanks
Shot blasting will remove the rust without reducing the overall panel thickness. If you’re happy with mig then carry on using it. It’s mostly down to preference and how refined with you work you wish to become. Cheers Trev 👍
Hi Trev. Been following your tig welding series and have bought the same tig welder as you.
Im also finding the 200amp torch abit much. I looking for a new torch possible a CK. However I want to use the footpedal. R tec have recommended there Wp9 I'm not sure if will be smaller and lighter than the orginal wp26. Your ck torch does look great but no footpedal. Any help would be appreciated
Hiya Rob I think RTec have a live question facility. I’m not 100% sure on the triggering function but I’m fairly sure you can use different torches with the foot pedal. I’m pretty sure the foot pedal bypasses the torch trigger because you swap the leads over. I haven’t looked at the welder for a year due to a building project so that’s where my head is at at the moment… I’ll be honest, I haven’t used the foot pedal that much, I have found it useful welding aluminium reducing the power once I’ve got the material up to welding temperature. I’ve found that welding sheet steel has greater stability with regards to heat dissipation, and using the foot pedal was mostly just an added inconvenience. The CK torch does give user a better experience , its a bit lighter, but most importantly for me I wasn’t fighting the lead. Obviously it’s not going to weld really thick stuff but for car body stuff it’s perfect 👍
What gauge of metal did you used here 22? It looks like there was no warping of the final metal unlike mig and flux welding.
nice vid trev thanks, was it the light weight torch or the tig welder you are giving away this vid?.....................the answer is comb it backwards first then use the cat.
Is part 4 coming? Cheers
Thanks for the very informative videos, Trev. I'm planning to do some body work on my old VW T3 Syncro and I'm totally new to this, so your videos are a great help. Do you use CuSi welding wire when you weld thin sheet metal like this?
Matthias Dongus no this is welded with a tiny bit of .8mm mig wire to act as a filler where needed. The trick is to get the gap as nonexistent as possible. The only time I’ve ever brazed stuff was on accident repair work with a mig brazing Machine. Cheers Trev
@@trevsblog Thanks a lot for the quick reply! Is there a reason you don't use brazing for restauration work?
Matthias Dongus I don’t really see what the advantage would be brazing? When we were mig brazing butt joints we had to leave a 1mm gap between the panels to allow a bead to form on the inside of the joint as the braze wasn’t deemed strong enough without that bead on the inside. When we TIG with steel filler the objective is to get as little bead as possible so that you can planish the welded area to stretch out the heat shrunk area without having a bead in the way. Cheers Trev 👍
Nice video, thanks, could you please turn on closed captioning? THANKS!
thank you!
I get mad at myself with tig, my son makes it looks so easy and gets a kick out of me cussing when I try to tig, but I’ll figure it out
A question regarding the TIG rods, Trev. I think the smalest size available for mild steel is 1mm (material number 1.5125 or1.5130) . I ordered 1kg for 6 Euro at an Internet shop but have not yet tried them. Are they too thick for sheet metal?
Tunicht Gut I’ve never used 1mm but I’m sure it would be fine. I use 1.6mm filler on wider gaps. I believe the more sizes you have the more options you will have at hand to help produce a good job. Cheers Trev
Hi Trev, is it possible to tig weld as per your video using a cheap inverter ark welder?
Not sure but possibly 👍 don’t forget you can by just a DC TIG welder which will still weld most things accept aluminium. Much cheaper than an AC/DC machine
Ooo you have a nice new R-Tech mig 180 now. Me too.Good aren't they? What are the consequences of having pure argon with a mig? My local gas suppliers only had pure argon so I got it, I've managed to get some lovely welds. Some of the best I've ever done infact. I'm really happy with it,, but I have turned the heat up a bit more than the recommended levels In the guide chart. 1, I'm nearly on 2. Also the crackle sound seems less than usual more sort of a hissy sizzle that a crackle. is this because of the pure argon gas?
Another great vid, another TTT cheers Trev 😉👍🏻
Argon is usually more expensive, but is better than C02/Argon mix. MIG users trying to save money, just use Co2.
happy days, I was hoping someone would say that . I had considered that as the reason but 5%co2 can't save much lolly. Even if argons x3 the price cheers Tel😉👍🏻
thanks again, that thing you do with the mig wire is awesome I haven't tried it yet but it looks good. I get so frustrated with trying to not only hold mig wire but even when you drop it on the ground its hard to pick up. and its so annoying trying to bend it straight and so on. so on your thin sheet metal videos, are you using pulse? to me it looks like you are not. and thats part of why I am checking them out, my machine does not have pulse.
Hi David no pulse, it’s no effort to gain total penetration to the other side so I see no need. Cheers Trev 👍
@@trevsblog yeah I got that part. but pulse isn't for penetrating from my understanding, I think pulse will help with preventing burning up thin material. ok so if I can see you do thin material without pulse then I know people can do it. I'm just trying to learn what can and cannot be done with or without whatever features or methods or whatever. I've been practicing on 22 gauge and I can weld it but with any gap I will burn it up. either way thanks for making videos. Ive been watching them to learn how to weld sheet metal for body work . I have some serious tough issues to fix on my old truck.
Provided you don’t have too many amps on you shouldn’t burn the material, but be aware that burning material when TIG welding could be another issue such as incorrect tungsten, not enough shielding gas, contamination including rust or an unclean surface etc or even not enough amps, sometimes the steel that you’re welding just won’t weld cleanly without the addition of filler rod as the silicone in the rod can help eliminate burning or porosity issues. Also the amount of time you spend in one spot can cause issues, one of the best guys I know welds at 30+ amps, but he moves very quickly and has hardly any heat spread into the surrounding panel, unfortunately I cannot see well enough to do this myself. Pulse can have many uses including getting great penetration on something like 3mm thick steel, the high side rapidly heats the steel causing the penetration to go deep but before it gets too hot in dies back on the low side preventing a blow through. Other people swear by using pulse on aluminium combined with using helium to aid with keep the welded area softer similar to gas welding, as gas welding has an annealing effect, this is something outside of my area of influence though. Cheers Trev 👍
@@trevsblog yeah i guess welding is very complicated. I'm actually doing pretty good on welding almost anything, but thin stuff is a challenge. I will just keep it simple and watch you do something and just copy it. like i said i can weld 22 gauge which is actually thinner than most body panels. but its the only thing the local store has on hand. but I find it interesting how you brought up rust and material not being good for welding. i purposely practice on not perfect fit up and not being perfect clean and welding without a heat sink in a vertical position, tryin to simulate what needs to be done on an actual car body. but yeah I will just keep watching and trying to learn some stuff.
Just had a thought, when you say the metal is burning are you referring to the edges melting back and creating a larger gap than you started with? If that’s what you’re talking about then you might find it useful to get some 1.6mm filler rod, concentrate the arc onto the rod rather than into the panel. This will allow you to bridge the gap between the two panels. Some people find it useful to almost lay the rod along the gap almost like welding three sections together.
Did I miss how you sharpen electrodes without a really expensive grinder that supports high production shops?
Rick Olson I’ll show it in an upcoming video. Cheers Trev 👍
I don't get why everyone use those "stupid" tig torches that you can't adjust. Get a Kemppi torch with a dual swivel head that you can twist and point in any direction you want.
Most of them will be using the "stupid " TIG torches because they are DIY welders , and that's what came with the welder . I assume you are talking about the TX 165 GS which in the UK costs around 270 pounds - way more than hobby welders want to invest . Plus , off bench positional TIG welding is always difficult even with a fancy torch especially on sheet materials. Which is why most pros use advanced MIG machines for bodywork. CK Flexlok torches are slightly cheaper , plus they can be had with the CK Flexi hose for around 50 pounds less than Kemppi.
I've searched the internet and can not figure out how to hammer and dolley a rocker panel/cab corner patch where I cant get a dolley behind. any tips for reducing warping where I cant use a dolley?
Samuel Churchill it’s not always straightforward I’m afraid. You can either remove more of the panel then do your repair off the vehicle but join it in a place that you can get to. If the inner is rotten you can replace the inner last using the missing inner for access. Or you can use a heat sink ruclips.net/video/1tdAgTCghUk/видео.html cheers Trev 👍
What grade or type of mig wire was used im assuming its not flux core..
Standard mild steel wire 👍
You can buy .030", .035" or .045" Tig rod these days.
TREV MEET MY DOG MACK 100 LBS PUPPY HE WAS AN ALLIGATOR BEFORE I CUT HIS TAIL OF AND I PAINTED HIM WHITE
You did have quite hurry to pull of torch and post flow did not get to the weld
Spent 10 minutes trying to read the subliminal message at 23:05 lol
DKR it was a glitch in the matrix 👍
Hi Trav's ... I really like your videos but I'm Brazilian and I don't understand what you say, can you enable Portuguese subtitles in your videos?
ah , better off with tig rods , more antioxidants in the real rods , or so Im told.
what is your email please trev
