🔨 Magnetic Ground Clamp - Hobart 770566: 500 Amp Review

I like the possibility to stick the grinder on the metal but again it has to be replaced with a clip just because I gave it 4 stars

Bought this clamp for projects that might not fit the welding table. Easy to move and provides the perfect base for welding.

It's a good idea to ground something if you can't clamp it down, but the magnet is too weak to support its own weight when it's upside down stands.

Ideal for steel. Unfortunately I switched to aluminum welding shortly after ordering, but still make minor adjustments to steel projects. Much easier than trying to crimp thick tubing.

Tried two of these in our shop on Miller 350P 300A welders. They lasted less than 2 weeks. They get hot and eventually fail. Our welders also didn't feel like they were providing proper grounding. We would classify them as household items or occasional use.

The mounting screw is much larger than any of the other cables we have from Miller and Lincoln. I had to drill and butt the connection. The magnet is weak. The plastic tab on the handle slips off every time. Very very bad design and doesn't work very well.
