    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.

    Nonconductive

    Plier clamps are good for light duty applications that require mobility, such as building a fence.
    Copper Connection—Clamps that are copper prevent weld spatter from sticking.
    Nonconductive—Nonconductive clamps won’t transmit electricity, meaning you can touch them while the power is on without disrupting the circuit.
    Cable Support—Cable supports prevent cable strand breakage.

    Standard

    Flat Jaw

    Spring clamps have an extended jaw that eases clamping. Both jaws carry current.
    Flat Jaw—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.
    Copper Connection—Clamps that are copper prevent weld spatter from sticking.
    Cable Support—Cable supports prevent cable strand breakage.

    Multiple-Angle

    Magnetic Clamp with

    On/Off Switch

    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.
    Multiple Angle—Multiple-angle clamps let you hold more than one workpiece at a time, at different angles.
    Copper Connection—Clamps that are copper prevent weld spatter from sticking.
    On/Off Switch—Clamps with an on/off switch let you engage and disengage the magnet for easy placement and removal of your workpiece.

    Ready-to-Use Welding Cords with Male Connector and Grounding Clamp

    Image of Product. Front orientation. Welding Cords. Male, Grounding Clamp Connection, Connector Orifice.
    The male quick-action connector on these cords gives your welding set-up greater versatility by allowing quick changes.
    Stranded Wire Class K—Stranded Wire Class K cords are good for general welding applications.
    Stranded Wire Class M—Stranded Wire Class M cords are often used in pipe welding because they’re more flexible and durable than Stranded Wire Class K cords.
