Welcome to the forum.

The usual cause of overheating is a bad connection, the cable connecting to the clamp should be tight and the clamp itself tight on the workpiece. The area on the workpiece where the clamp fits should be cleaned back to bright metal.

If you have a crocodile clip clamp you'd be better off replacing it with one that you can screw down.

thanks for the advice is the copper mesh supposed to be touching the metal ?

Any chance of a picture? Is the mesh you refer to the cable between the clamp and the welder, or is it a short piece that connects the two halves of the clamp?
