I'm just wondering about earth clamps for arc welding . I can't seem to get a good one . I was going to clamp the earth lead to the work with a vise grips I was going to put some brass on the jaws. Would this be a good idea
Why cant you get a good one? How big is the machine?
A Myking 600A is a good one, readily available and under £20.
If thats a bit spendy, and you want crocodile type, get one thats ratted higher than your machine.
Its worth having a pair of different earth clamps on the same lead, one type never seems to do all you want. My other lead has a G clamp and mag on it.
