Ok, I will admit that my machine had built in water cooling for the welding head... and would weld 1 inch Aluminum....So I changed the head to ' gas cooled' ( argon ) so I could weld normal size things....

"warp the snot out of "
Randy was absent the day they went over ' tack welding' and ' segmented backup welding' ....
ALSO.... pick up that CO2 fire extinguisher... or have someone else running water over the metal near the welding....
LOL
