Thanks, Keith. I learned to weld in a college course. The first thing he made us learn was how to butt weld cast iron with an oxy-acetylene torch and a mild steel filler rod. So, I have the basic understanding of how to use filler rods. Plus, I've done tons of brazing on the farm over the years with an oxy-acetylene torch. This looks like the same basic procedure except the heat is from the tungsten electrode and can be controlled so much better and so much more precisely. Looks like the learning curve might be getting the hang of using the foot pedal to control the heat/arc.
I could add it to my big Miller out in the farm shop, but I want to be able to do it in a little better environment in my heated/cooled gun shop.
Running off 240V it should be plenty big enough to do anything I'd want to do on guns. One video I watched told about using a .020" tungsten electrode and getting the amps down below 5 to do "micro-welding".
I appreciate the input. SRH
