    Looking for a ground clamp for my Miller 211. I saw a comment that the 300 was too big for the ground that comes on the 211. I would like the somewhat bigger opening on this clamp. Do I have to change the ground cable also or does this really fit?
    The GC 300 should fit on the ground cable that is on your Millermatic 211. If for any reason it does not, you are more than welcome to return it and we will cover your shipping cost back to us. We know that the GC 200 would definitely work- so that is an option as well. It has the same clamp opening as the GC 300 and is a 230 Amp clamp.

    Easy to install. Good clamping pressure. Established superior grounding for welding over factory Miller clamp(s).

    Not the clamps fault but too big for the ground wire that comes with the Millermatic 211.

    Good quality clamp

    I like this better than the clamp my welder came with. This is more stream lined and is thus easier to grab onto smaller object. The clamp power is good for hanging on tight to your work. Tip: I was able to unbolt the lead from my old clamp which used a large flat wire connector with hole in it for the bolt. By bending (rounding) this somewhat in the vise it was able to slip it right into the hole in this new clamp. So no cutting needed and it has a great connection that won't pull out if it gets tugged on.

    Quality ground clamp

    I needed a good ground clamp for my Hobart MIG welder (they come with a cheap clamp) and after seeing Jody's recommendation on his web site, I sought one of these clamps. It is cast copper and has a strong spring. It was shipped quickly and packaged well. If you have a welder with a sub par clamp, a good clamp like this one will make a big difference in the welding process, especially with MIG welders.

    Arrived fast and in perfect condition; the price was right... what's left to say?
