Cold tig welding
These have been on YouTube for awhile, wondering what the you think about it?

TIG pulse welding
I have demo'd a similar machine (Orion, Sunstone) Very nice technology. It works like the video, however, I would not touch the chain of welds. It is not totally cold. I also tried to program a Miller Maxstar to do a short pulse after a lift start. The Orion does a better job of controlling the whole timing. The tungsten automatically pulls up and the pulse is coordinated with that motion. It can work on a machine with lift start and pulse program-ability, but you have to do the pull up part. The Orion was real easy to use, even for a non welder. You probably want to be a good tig welder to do the lift-start/pulse. The Atom machine in the video uses ultrasonics to move the tungsten. I have no experience with that.

I saw that review and I think they have valid points. I do wonder if it would be good for sheetmetal, especially thinner material.

That’s more or less how I tack butt welded panels together. However the welder having the timer is going to be more consistent than me bashing down on the foot pedal and instantly releasing it. I’m older and I’m tending to get cheaper about buying new tools so I guess I will just stick with the older method a while longer……….. it does work. I will just add that I don’t try to tack the whole panel together, once everything is locked together with tacks I run a normal tig bead. Has anyone in the group ever gotten a paying job to weld razor blades together ~ John Buchtenkirch

I want to see the back of the welds.....
but even with that if you are not using any filler there are going to be lower areas in the "valley" between the 2 pieces unless you are welding razor blades ! I wish it was that simple and I could be an expert welder when I buy a $400 machine

Hi,
Interesting! I watched the YouTube video and I agree, fun to play with, but not sure the practical application. If you were in the market for a new TIG welder, then maybe? But even then, how well Is the TIG function? The video shows high current for relatively thin (1/8") steel and aluminum welding was not even discussed. There's a lot of things I could spend $400 on and I can weld soda cans and tin foil with my Thermal Arc TIG. B

Poor penetration. They call this cold welding for a reason. The promoters claim that it's the same as a TIG with pulse. That is not just misleading, it is FALSE!!! This system goes from full temperature when you pull the trigger, to completely off when released. A TIG with pulse is preset to operate in the on position as long as the trigger or foot pedal is engaged. You preset the high and low temperatures desired and the time for each. The metal never gets "cold". It goes intermittently hot and very hot. Huge difference between that and on/off. When you buy cheap Chinese aluminum parts that appear to have near perfect TIG welds, this is most likely how they were welded. For an aluminum overflow tank it might be OK, but for anything carrying a load or structural, no way. Caveat emptor.
