What size earth clamp?

Hi,

The earth clamp on my 90a sip mig welder has broken, what size in terms of amps do I need for a replacement they seem to range from about 200a to 500a

Thanks
Chris

I like the cheap but heavy earth crocodile ones, the ones that give your wrist a workout every time you use it.

Bought one of these as a cheap fix for a machine I was selling, I was pleasantly surprised for the price. Copper - check. Braid - check. Wrist workout - check.

We use brass spring types at work, pretty decent.

No one clamp does all, on the moblie set I have piggy backed the clamps. The screw up clamps are much better hanging off the edge of plate.
