Grounding Clamps for Welding
Designed specifically for use with welding circuits. Clamps that are copper or have copper-plated components prevent weld spatter from sticking.
C-clamps tighten with a handle. Use these multipurpose tools for strong clamping in nearly any application. 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 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. Clamps with an ABS plastic handle have a cushioned grip that’s comfortable to hold.
Plier clamps are good for light duty applications that require mobility, such as building a fence. Nonconductive clamps won’t transmit electricity, meaning you can touch them while the power is on without disrupting the circuit.
Spring clamps have an extended jaw that eases clamping. Both jaws carry current. Flat-jaw clamps grip flat surfaces especially well. They have a larger contact area with the workpiece than standard spring clamps, so electricity flows more easily, but their jaw openings aren’t as large.
Magnetic clamps stick to metal surfaces on your workpiece, even oddly-shaped and sized ones. Compared to traditional clamps, they require less manual effort and are less limited by the amount of space available on your workpiece. However, you can’t use them on aluminum or nonferrous material, and their hold is usually less powerful than traditional clamps. Clamps with an on/off switch let you engage and disengage the magnet for easy placement and removal of your workpiece. Multiple-angle clamps let you hold more than one workpiece at a time, at different angles.
Cable supports prevent cable strand breakage.
