I seem to recall having seen two or more welders working on the same structure at the same time. Was that for real? Is that OK and normal?
If its ok, could I run different welders of different sizes and source voltage at the same time? I've actually go three wire feed welders. An old Harbor Freight blue box which I have not used in years, a Lincoln ProCore
120V I actually use all the time due to its small size and ease of portability, and a Miller 212 (not autoset) I originally bought for aluminum welding, but lately have been using more often for steel due to its decent duty cycle. When I was putting together my welding table frame during the weld out a couple times I thought it would have been nice for my son to burn wire with the 212 while I burned wire with the ProCore.
