Wow thats an impressive oration there, trouble is, You failed to refute the fact that we used Helium with MIG.
I only claimed that WE in our little shop in the USA ARMY in Korea where for the first time in my life I was evolved with welding, the folks who trained me called it Heli-Arc MIG so I guess they are bunch of JERKS also!
They and I may not know the difference between Heli-Arc MIG and Heli-Arc TIG but we do have enough decency not to get on this board and call people names.
You better go look again at the MIG machines, you missed the boat fellow I have 3 machine that are "Constant Current power supplys" (not counting SAW machines)with a computer up front that "Constantly changes" the current (its called PULSE) when we are MIG welding. Or have'nt you heard, you can do more than Short Arc with them?
Have a very nice day.
