This isn't resistance welding, it's TIG fusion welding with a short arc and blunt tip (so the arc wanders around the tip rather than burning through at a point).
Can afford a tig welder but is on a budget 🤔🤔 awesome videos man, been watching your channel for years and learned most from you. Keep up the good work. Thanks for the free lessons homie.
Grr trying to join galvanized 12 gague wire to other 12 gague galvanized wire... nothing I'm trying works... basically I have a mesh fence that needs patching up anybody know what I should be doing?
You can also use copper as a filler on steel similar to using silicon bronze, If I can’t find a piece I will buy a metre of 120mm2 earth wire, strip it and then use the strands. You can usually run 1/4 to 1/2 the amps it would take to weld, I find it’s useful for joining thin / small sections or just to put copper on something for decorative or conductive electrical connections
Dude,, You are awesome !! I was curious if TIG could spot weld and as you just showed us,, it can,, Thanks for explaining why to cut the cup, I would probably would never had thought of that.. Much Luck to you ) ... JRG
The very first MIG welder I purchased back in 1982 had a special shroud for spot welding that did not require a pre drilled/punched hole. Just fit the shroud and switch the machine to spot weld and set the timer according to metal thickness, I have not come across another machine since then that has this function.
Thanks Justin These tips are great. Is there a quick tip for determining the amps needed for thin metal tig welding. is there a ratio like 1 amp per thousandth of an inch ?
GREAT info! I was looking at purchasing a hand held spot welder when I found this video. I've got a Miller TIG so I'm good to go now! One question,... I'm assuming I can do the same with aluminum???
worked great on a nice clean control piece but when I tried it with my first production piece it blew a hole in it. I wonder if it is the age of the steel..
Nice and informative video! I have a small spotwelder (working with mosfets) for small objects but now his big brother for the bigger stuff! Way to go, I like your style of sharing information!
For an application like that you could also use copper wire instead of the silicone bronze. I use it where I want to fuse thin non structural sections or brazing TIG filler to sheet and usually run about half the amps I would use to weld. If I have to buy it I will buy 1 metre of 120mm2 earth cable and strip it, each strand is about 2mm diameter
Do you like 🦉or 🥒? Now ask yourself your same question to me again. If you can't answer, the same gloves are available in black and tan color from WeldMetalsOnline.com
Question. When I try to braze I get flash back. It’s seems like the bronze rod blows up kinda. ? And there’s a bunch of spider webs around Any insight?? Thx
@WeldCoachOfficial he's most likely welding galvanized with silicon bronze and is just welding too hot and not concentrating the arc just on the silicon bronze.
Although it works well, this technically isn't resistance spot welding. It's still forming an argon plasma arc, which is why you need the argon. I make my own two layer gas lens screens using steel mesh and I spot weld them together using a TIG welder but treat it as an actual resistance spot weld. You don't need any cup or argon for this. Simply touch the flat end of the tungsten directly to where you want the spot weld and apply light pressure. Treat it exactly like a spot welder. You can use a 3.2mm tungsten rod in the ground clamp to sandwich your sheets together similar to the animation at the beginning of the video. Make sure you adjust your current and use the timer feature on your machine if you have it. If not, tap the switch for less than 0.5s and you'll end up with a perfect spot weld on very thin stainless steel mesh. The reason I spot weld those is because the mesh is so thin that even a 5A arc is far too hot and will quickly melt and ruin it. I've since built a custom battery tab spot welder that inputs a precise amount of energy and the results are of course significantly better.

Great video but you said you have a tig welder and a limited budget. I think that is a oxymoron. seriously I watch every video you come out with, all great content.
