Can someone just confirm where the attached lead plugs into please? my guess is into either the plus or negative but then where do I plug the earth cable into ? I’m going to be welding gasless
For gasless MIG welding, connect the lead coming out of the welder to the -ve terminal on the right (the one that says "no gas", and the return ("earth") lead to the left hand (+ve) terminal. The polarity isn't marked, for some reason. Other images of the same (?) welder do show the polarity.
