It could be done on Aluminum, but would require a spool gun and a MIG that could weld Aluminum. We have not experimented enough with settings and pre-heating the metal to give good welder setting suggestions for Aluminum welding with this attachment, but with some tweaking it could be done.
+GARRY GIBSON Did you try removing metal from a Nozzle? Did it work? I would think that you wouldn't want to remove metal from your Nozzle, because that would put your wire tip in the wrong location.
It's a bit misleading to call this a spot weld when it is not. What this is ,is a puddle weld or tack weld. The welder is adding material to a pre prepared hole to weld the two layers together. A spot weld is a pool of molten metal caused by clamping two layers of metal together and passing a high current through the joint. Once the metal is molten due to the current ,the electrodes are pinched together to fuse the two layers together. No metal is added or taken away. In a high end restoration it is considered to puddle weld joints together rather than spot weld,as per original production manufacture.
looks like an awesome product, but I'm a little confused. In the first scene it looks like two sheets of metal are welded together without any hole drilling, while in the second, it looks like the holes are pre-drilled. If the pliers stabilize the tip of the welding gun, which it looks like they do, how is the gun making contact with both sheets to achieve a good weld?
Both can work! One is called "plug weld", one is called "MIG spot weld". Pliers are not related to the gun at all! Both sheets (which should be clean by the way) are clamped together, so electrically they're one thing. You melt through one, then into the other.

I see some guys who want to modify their existing Nozzles to try to do this job. But, cutting your existing Nozzle moves the wire feed tip too close to the sheetmetal. Another guy wants to weld tabs onto his existing BRASS Nozzle -- welding brass takes special equipment (and talent), and of course the point in buying a tool is the convenience of having someone else manufacture it for you. I suppose you could make a spacer, but why bother? The Nozzle is inexpensive, just buy it.
No body said cutting the nozzle. They said cut out a nozzle and slide it on. Copper pipe and can be cut and pliers can be welded as Garry described. These are just gimmicks and conversation items for those who want to blow away dollars.
As long as you have the spool for welding aluminum, along with the correct equipment, and skill to do it, I cannot see why it would not work out. I've learned from a guy that works in the hardware department of a large store that sold tools, equipments and supplies. I worked in the neighboring auto department in the same store, at the time. The hardware guy that worked there before left long ago, hes one of those guys that are good to work with, and knows things too.
Does this still require a spool of filler wire to be used? If so, its then not really spot welding. Yes, it makes a spot,yes,it welds, but is more like controlled mig welding..If you do your research you will find that 'real' spot welding involves resistance and localised pressure, and has no filler material.Real spot welding is also called resistance welding. Good vid and helpful to mig owners,but inaccurate.
Those pliers look like alignment shims welded to vice grips, and the nozzle looks like recessed mig nozzle cut with openings.

Can you do a spot weld without any drilling holes?
I have a gasless mig. Can this be used? (Fluxcore)
cheers il go cut out a nozzle and mod sum pliers

@@NickeyChevelle get a recessed mig nozzle and cut the opening to be flush with tip.
alignment shims

How do you expect to do that while working on a car, for example changing rocker panels?That just can't be done without access to both sides of metal.

Will this work with the Miller 211
Thank you for the message!
Is that a blow thru hole I see @ 0:38?
No.
you have good eye
its just plug welding with a bit of help. you still have to drill a hole
i wonder if i could just cut a normal mig tip into that shape? hmmm might try it. thanks
That is exactly what I did when Machine Mart did not have any plug weld shrouds in stock.
How is there no build of with mig but so much penetration? Must be a massive 3 phase welder

Inexpensive means less money in wallet.
@@FrustratedBaboon if you can't afford 35 dollars you can't afford restoring a car. Go ahead and NGR rig your own.
@@BruceLee-xn3nn what does ngr mean?..
recessed mig nozzle and cut the opening flush with contact tip.
Boa ideia para solda ponto.
Does he move the gun during the weld or is he just holding it like a tack?
You can move the tip slightly in a circular motion to fill in the hole, if necessary. But it's very little movement.
Can it be done on high strength steels?
Regular steel can be welded, I cannot see why high strength steel cannot be welded.
Can it be done in aluminum as well?

Is it safe to watch a welding video without eye protection?
Shit wish I'd read that before I watched it
Well, obviously the metal tears. . .
Ya stolen my idea I thought I was being clever haha
Plug welding…
no
that was not worth it.
