MIG Welding: Using a Magnetic Ground
The Voice: Hey, Kevin. What are you wrestling with?
Kevin Caron: My clamp died while I was working on this metal art sculpture here in the studio.
This is the old ground clamp that used to be on Murph, my MIG welder. And where the electrode or cable attaches right here, it melted this aluminum away. It completely melted away and I lost the ground, so it quit working.
Rather than go back to this old style of clamp where you have to get them onto a piece of metal someplace, they've come up with something new. It's about time.
This is a rare earth magnet. When you put it up against a piece of metal or steel (can you see this?), let it stick; turn the knob, now it sticks. So it doesn't matter where you put it.
If you've got a big, flat surface you're welding on, stick it up there and turn the knob. It sticks right where you put it and you've got a good ground.
You can get it out of the way, overhead, on large pieces of pipe or big square tubing or something. You don't have to wrestle and try to get your ground clamp on. It's pretty cool.
See you next time.
