I have a Lincoln promig 140 and the instructions say to reverse the polarity between flux core and gas welding.
I read a article lastnight that said that having the power feed on the + side while using gas, as instructed, would result in less penetration and an eratic arc.
Is this correct? should the polarity be reversed based on using gas or not?
thanks in advance
Greg
