Magswitch Magnetic Ground Clamp - 300 amp
June 8, 2012
Had the 200 amp version and it worked great, though less holding power so the heavy grounding cable would pull off if under any tension. Decided to put that one on a lower amp MIG with a lighter ground cable and use this one for the TIG. Works great and holds fast.
ProsEasy to use - even with one hand.
Can clamp to a flat surface
ConsCan only be used on ferrous metals, though you can clamp it to a ferrous work surface if you're welding aluminum
