Magnetic Clamps


Style A	Style B	Style C

Style D	Style E

Hold magnetic workpieces in place.

Style E—Style E clamps have a handle to help pull them off surfaces.

Copper-Plated Steel Body—Copper-plated steel clamps won’t scratch steel surfaces. Their plating also stops weld spatter from sticking to their surface, so sharp spatter won’t cut you or your workpiece.

Easy On/Off Magnetic Clamps


Style A	Style B	Style C

Style D	Style E

Switch the magnets on these clamps on and off for easy placement and removal of your workpiece.

Style E—Style E have magnets on opposite sides that can be turned on and off independently, letting you adjust one workpiece while the other remains clamped in place. They’re commonly used to weld two pieces of metal together.

Grounding Clamps for Welding

Designed specifically for use with welding circuits.

Magnetic Clamp


Magnetic Clamp	Magnetic Clamp with On/Off Switch	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.

Outside-Clamping Magnetic Clamps

Clamp workpieces from the outside at a 90° angle, leaving the inside free for welding or fabrication. You can also clamp on the inside at 45° and 90°.

Three-Axis Magnetic Clamps


	55 lbf Maximum Magnetic Pull	75 lbf Maximum Magnetic Pull

Hold and align up to three workpieces at 90° angles. Three magnetic faces clamp parts along multiple planes simultaneously, so you can tack-weld corners and T-joints without repositioning or using separate fixtures.
