Micro TIG welders

Shawn:

After watching several of the videos for the Orion/Sunstone/Lampert type of welder, including a couple taken at ultra-high frame rates, the arc doesn't always occur. When it does occur, it's when the electrode is retracting. The high speed images show the metal heating and the puddle forming before the electrode retracts. I think these things are argon shielded resistance spot welders. They aren't using the heat of the arc to form the puddle, the puddle forms and then the arc sometimes occurs at the end of the cycle as the electrode is being retracted out of the puddle.

The "random Ali Express version" that Blender gave a link to appears to be the welder used in the German forum that Krewmember had a link to. That guy looks to be available for about $500 in the states and that just might be an option.
