Default Re: Welcome To The Welding & Metalworking Forum

I got a few magnets meant for welding, those triangle laminate with steel of various sizes.

When I got the minimal training to use time at a shop welding we had a thick metal table, but stuff stuck to it as it was steel. They used a wire brush occasionally to clean off weld splash beads.

It was said that with the magnets holding the pieces to weld on the table and the table had the ground clamp connected that enough current flows for what otherwise small pieces the clamp connection would be impractical.

You’ve explained about the copper and that it does not stick but is a very good heat sink, thanks.
