Grounding Clamps for Welding

Designed specifically for use with welding circuits.

C-Clamp


Heavy Duty	No Twist	No Twist ABS Plastic Handle

C-clamps tighten with a handle. Use these multipurpose tools for strong clamping in nearly any application.

Heavy Duty—Heavy duty clamps have a strong frame that won’t spread when holding big workpieces, such as large diameter pipe and thick plate.

No Twist—No-twist clamps have jaws that move in unison to apply even pressure and prevent twisting while securing your workpiece. They’re also known as cantilever clamps.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

ABS Plastic Handle—Clamps with an ABS plastic handle have a cushioned grip that’s comfortable to hold.

Copper-Plated Steel Screw—Clamps that have copper-plated components prevent weld spatter from sticking.
