Welding Issue FYI

[hotrod1]

I have been using clamps and magnets for a long time to hold pieces together before tack welding. Never had an issue. The other day I got a new magnet. This thing is amazing. It has an on and off switch. Once turned on, you can not move it or take it off no matter what you do. It is strong!

Anyways, used the magnet to hold things together the other day and tried to weld. Could not do it. It would not weld (see picture) I was not sure what the problem was. Thought it was the gas or the ground, or not clean metal. Worked on it for an hour. Gave up and thought it was the welder. After thinking about it, I remember reading about magnet issues and welding. Took off the magnet and all was good. Go figure.
