We've all been there: you're in the middle of a long bead, and suddenly your arc starts sputtering, popping, or cutting out completely. You check your settings, check your wire, but the problem is actually down at your feet—a cheap spring clamp that's slipped off or isn't making good contact. The Weld-Mate NT-665 600 Amp C-Clamp Ground Clamp is the solution to those headaches. This isn't a flimsy clamp that barely hangs on; it's a heavy-duty beast designed to bite into the metal and stay there.
The C-clamp style is a favorite among pipe welders and structural fabricators for a reason. You can crank this thing down tight, crushing through rust, scale, or paint to get to the clean metal underneath. Because you control the pressure with the screw handle, you don't have to rely on a spring that gets weaker every time it gets hot. This clamp is rated for 600 amps, meaning it can handle the heat of heavy flux-core or gouging operations without melting down or turning into a glowing resistor.
The solid copper alloy construction ensures that the power from your machine actually makes it to your rod or wire, rather than being lost as heat in the clamp. A cooler running clamp means safer operation and less time stopping to let things cool down. The T-handle is big enough to grab with your welding gloves on, so you can move your ground quickly when you need to reposition.
Whether you are welding on I-beams, heavy pipe, or thick plate, the NT-665 gives you the confidence that your ground is solid. Stop fighting your equipment and start welding with the consistency you expect. Upgrade your lead with a clamp that works as hard as you do.
