OVERVIEW

Instant Grounding, Zero Hassle

Every welder knows the frustration of trying to find a good ground on a large assembly. Traditional spring clamps need an edge, and tacking on a temporary tab takes time you don't have. Enter the Tweco Switchable Magnetic Ground Clamp (SMGC300). This tool changes the way you set up your weld.

With a simple turn of the rotary knob, you activate a powerful magnetic field that locks the clamp onto your workpiece. It doesn't matter if you are working on a flat plate or a round pipe—the specially designed V-groove base grips it all. Rated for 300 Amps, it handles most standard fabrication jobs with ease.

The best part? Cleanup. Old magnetic clamps are nightmare magnets for metal fuzz and grinding dust. The SMGC300 solves this: just turn the switch to "OFF," and the magnetic field collapses. All that steel dust simply falls away, leaving your contact surface clean and ready for the next arc. It is a small upgrade that makes a massive difference in your daily workflow.

FAQ

Simply place the clamp on a clean, bare metal surface and turn the rotary knob to the 'ON' position to engage the magnet.

It works on ferromagnetic materials only (like mild steel). It will not stick to aluminum. It may stick to some grades of stainless steel, but generally, it is designed for carbon steel.

The SMGC300 is rated for up to 300 Amps.

Turn the switch to the 'OFF' position. The magnetic field will deactivate, and the shavings will fall off or can be easily wiped away.

Yes, as long as the amperage is within the 300A limit and you have a good clean contact patch.

Yes, the V-groove is designed to center the clamp on round stock, providing two points of contact for stability.

Typically, this unit connects to your existing ground cable via a lug or bolt connection point on the clamp body.
