- I picked up a spot welder from Harbor Freight to use on my Jeep rebuild project, and decided to do some upgrades to it.

New tool, never used, imediate teardown. I like it!
One could say that its the AvE school of approach, but with much less ``quality and endurance testing`` if the object in question...
@@camillosteuss AvE would leave it for the pixies - Jeremy actually makes it work better (at least for his use case) - an inspiring man!
Don't you have a lathe to work on?? Stop watching youtube videos and get to it :)
@@mumblbeebee6546 i agree, but keep in mind that ave isnt an imbecile... he makes content through destructive approach to tools, as a form of quality inspection, not as a review of a personal tool he got for his own uses... Now the fact that his lathe and mill when seen are an absolute mess makes that point a bit shaky, but that notwithstanding, ave is a man of intelligence and practical skill, and i have learned immensely much from him, watching him for last 12 years... mostly in regards to material chemistry, but in other areas aswell... That is not to say that i am not enjoying Jezza greatly... In fact, it was AvE, over a decade ago that first peaked my love for machinery and started me on the path of actively learning about machining in my own time, and now i actually am a machinist, over a decade later or so...
Yeah, Ave is who inspired me to get a mill back when he was more a manual machining channel
Did the extensions need to be copper? Isn't the copper just so they don't stick to what you are spot welding, or is there more to it than that?
So the tips are replaceable, but the tongs are still copper. I think if they could use something cheaper, they would. I believe it has to do with copper having a very low resistance and the high amperage this thing is pushing through them, so I figured it was best to stick with what I knew would work.
It requires a lot of amps (at a very low voltage) to make a decent spot weld so you need ALL of the conductivity you can get, especially with a 'lightweight' machine like in the video that doesn't have a huge transformer creating thousands of amps.
Impressive how you fully dismantled a new tool to make it so much more useful. Harbor Freight sells Starter Kits for everything 👍😎👍
😂 starter kits. I love it!
Every time you bring something new in the shop, first thing you do is taking it appart and pimp it. I think it's brilliant :)
Always learn something new from your videos. Keep up the great work!
Hear me out.... try sour cream as a lube for copper.
I was waiting for you to sharpen the copper rods then bend them...making them extensions to the existing bars was a damn good idea.
Totally agreed, that was smart!
Very cool! I have the 110V spot welder for putting together AK flats. I did not need as much mobility as you, and as such I hillbilly engineered an old Tig Welding foot pedal to run the current so I could maintain better control of my work piece. Just a thought if you were doing more stationary work.
Love the blackened “chainsaw” handle. The whole project came out looking really cool, but my favorite part is the blackened handle🙂👍
This video really hits the spot!
One is basically welded to the screen!
*zaps
Tacky, tacky, tacky!
Hello, I am planning to use this spot welding machine to solder copper foil but don't know if it is possible? Can you help me make a video about using this welding machine to spot weld copper foil?
Because I'm not good at English, I used Google to translate the words. If there are any mistakes, I hope you understand
It would not work for copper, only steel.
@@JeremyMakesThings Thank you very much
It just dawned on me while you were turning that piece at 8:45 that you are a sculptor! You take an old misshapened piece of metal and uncover a nice beautiful piece hidden within.
Indeed, thread locker is annoyingly sweet. 😂
If the tool is already too heavy and awkward, I'm not sure that putting a solid steel forged handle bar on it is going to help with that...
It was more awkward than heavy. It’s much less awkward now.
@@JeremyMakesThings And the handle should outlast the tool by at least a couple thousand years!
Cool upgrades. I would’ve went with a lighter handle out of plastic because holding a transformer is heavy as it is.
oh no, warranty void
Went from 27 lbs to 37 lbs. I'm just jealous though of your shop machinery
Loctite that tastes bad? Must have been a generic threadlocker???
Last I knew, red has a sweet taste. But, I do not recommend it.
I have one of these and thanks for the video, now I know I can make a longer cord. I think I'll have to make my own video on changing the cord.. They work great, I got mine on sale for $99
Whow, that forged handle would be fine for a tank or a battleship...😄
Anyway, really love your videos and especially your comments!
A small spacer would have been better than filing the gusset which weakens the casting.
what would happen if you use steel for the rods? like you probably don't what the tips to be steel or they will weld to sheet metal, but would steel rods be fine for an extension?
That copper looked like you were turning playdoh
It’s so gummy!
The extension will increase the induction and reduce the output but if it works it works.
Hey man, looks pretty cool! thanks for sharing!, always fan of your videos
Oh no there goes the waranty!
Well done 👍👍👍. Thank you for sharing. Be safe 🇨🇦
Next he needs a counter waited rope stand to make it easier to work with😊
Is that paddle a Backlund, or a Snyder
Snyder
i burned my first one out by (i think) the switch stuck in on position
Ooh, I can see that happening. With as simple as this thing is, that’s probably about the only way to kill it.
I’ve got an older Miller spot welder with a timer. It was in the scrap pile, needed new power cords before I could use it, and ironically (cupronically?) the long offset tongs that I wish were shorter!
What type of nema plug did you use?
I’m always changing my mind on putting twist or standard spade 1ph 220/240v outlets in my shop.
All my 240v outlets are 6-20 outlets- they were put in for my CNC router, mill, lathe, etc. at some point I’ll need to add a 50amp outlet for EV charging, and then I’ll swap the welders over to that, but for now it works.
My Central Machinery Spot Welder had a copper shim around the upper tong. I assume this was a correction for a factory mistake, making the upper bore .0020 oversized. Did your welder have a shim on the tong? You can see my welder at ruclips.net/video/Dn-O_1799mA/видео.html .
Yes, it has the shim as well
Well you've done it this time! I am -gasp!- giving up on a project because of this video!!! I am NOT going to make a spot welder from a previously pilfered microwave transformer! Hello, Harbor Freight? AND now I have a couple of projects to replace the one I just discarded - THANKS I think!!!
Now what can I do with a transformer that has the secondary removed? Oh I'll find something!
Love how the CJ is coming along. Keep up the great work and videos.
I subscribe to Jeremy Makes Things not.......... Jeremy Modifies Things.
😛
Dont try this at home?😳
Jman
I'd like to see you try and return it now. 😂
“Do you want the two year protection plan.” “Uh, no thanks.”
Yes, I have that one - and yes, it works better than I expected…
I call it “Cow Warpington” after the infamous Cal Worthington commercials I recall from ages ago - and how he invariably had some non-canine handy, *which he referred to as “his Dog, SPOT.”*
It’s a *SPOT* welder…
I really wanted to give this video a thumbs up but it was 666 and I couldn’t bring myself to screwing with something so unusual
😮😮😮. ,,AS YOU GO ⁉️
Yeah, I like this guy. Fun watch. Thank you and I subscribed👊
I am wondering if the on / off switch could be changed to a foot peddle and a 220 volt relay.
Well, that escalated quickly. Nice work!
You made it even heaver! good job, jealous of the lathe and milling machine.
Hello please help me lm looking for the machine

👍👍
Would you be will to sell the Extension arms
Also where did you get the long arms from?
Got 5/8” rebound copper rod from EBay, and then just threaded them to mate to the existing tongs as shown.
Did you actually watch the video?!?
What does red Loctite taste like?
Not sure, I’ve only tasted blue.
That's a lot of work to improve a tool... well done! The final product operates without much sound, so you need to add a buzzer to it.
😂😂😂
? from a electrical safety, would it be safer to put rubber tubing around the new handle in case it has a short you wont have a circuit through your chest?
So one of the tongs is actually connected directly to the case- so the whole case is “live” but you would have to touch the other tong to complete the circuit. The reason it’s not dangerous is the voltage is so low on the “hot” end (maybe 1 or 2 volts) that it wouldn’t overcome the resistance of your skin. If the line voltage side shorts out….that side is grounded, and you would still be holding some other metal part of it anyway, so I don’t think trying to insulate the new handle would be necessary. Might be more comfortable though.
This guy! 😂 Love it!
Give the welds a chisel test
Why cant anyone separate the pinch tips from transformer (main body) with leads like the leads on welding machine and let most of weight sit on floor (cart). Looks like would be more agile to fit in tight places with less fatigue on arms. Is this just a cost thing What am I missing ? Folks been dragging welding leads forever. Better yet, this would be a handy accessary to use with welder already in shop. Open to suggestions.

The spot welder only outputs a couple volts, so even the slight resistance of lengthy copper leads is enough to drastically reduce the welding current.
You do not have the arm strength to push two pieces of metal together for a proper SPOT WELD.
Spot Welding
What is spot welding? Simply defined, spot welding is “the welding of overlapping pieces of metal at small points by application of pressure and electric current.”
How to spot weld? Spot Welding occurs in three stages:
Electrodes seated in a weld head are brought to the surface of the parts to be joined and force (pressure) is applied
Current is applied through the electrodes to the workpiece to melt the material
Current is removed but electrodes remain in place at force to allow the material to cool and solidify
Spot welding times range from 0.01 sec to 0.63 sec depending on the thickness of the metal, the electrode force and the diameter of the electrodes themselves.

Oooooooooo
About to do the same trick, when you bent the copper extensions did you heat them first?
I didn’t bend them, I just made threaded extensions for the existing tongs.
@@JeremyMakesThings Ahh makes sense, thanks!
Did you actually watch the video?!?
@@Voo_Doo_Blue thanks for the jerk off comment, wasn't initially clear to me that he only tapped, so I asked. But well done with shaming people for asking a question. Goof
Use Your Brain,
You Donot Need Long Bars.
Amén.
Beautiful "HACK",thanks for the look! Wonder if Harbor Freight is watching?
Thank you for not doing a "review" video, absolutely hate those types of videos, and unfortunately way too many RUclips creators are going down that road and losing 📉 followers, because most people are here to learn how things are built not how much something costed and "performs" with the video being sponsored by the maker of the product, don't get it wrong, they're a few people that buy stuff theirselves and really "review", but really enjoyed your way here of doing better!!!👏👏👏👏👏👏
Rule number one, don't use it before tearing it apart
