I have to weld 1/4 inch steel plate to 3/16 steel tube. what amp and wire feed rate should I use. It needs to be heavy duty. Also since Im running an argon, co mixture should I switch to solid core wire or stay with flux core wire.
I have a three hundred amp welder. with digital read out, the welder is new to me, before I had a hobart handler 175 but it was maxed out all the time. and I havent spent much time welding. thoughts?
