Tweco W180SGC 180A Steel Earth Clamp

Get a Grip on Your Weld Quality

Every welder knows that a good weld starts with a good ground. If you are fighting an erratic arc, experiencing hard starts, or noticing your ground clamp getting dangerously hot, it is time for an upgrade. The Tweco 180 Amp Steel Ground Clamp (W180SGC) is the workhorse you need for your garage or light fabrication shop. Designed to handle up to 180 amps, this clamp is perfect for your 110V or 220V MIG welder, as well as smaller stick and TIG machines. Don't let a loose or flimsy connection ruin your bead; clamp on with Tweco confidence.

The W180SGC features a rugged steel body that can take a beating. We know that ground clamps often get tossed on the floor, stepped on, or dragged around the shop. Tweco built this unit with that reality in mind. The heavy-duty spring provides a powerful bite, ensuring the jaws dig in and stay put. This strong contact is crucial for maintaining a smooth, buttery arc, especially when working on thinner gauge materials where precision matters. The steel construction also resists spatter adhesion better than some softer alloys, keeping the mechanism functioning smoothly for longer.

Swapping out your old clamp is a breeze. This unit is designed for easy cable attachment, getting you back under the hood in minutes. Whether you are fixing a muffler, building a welding cart, or doing art fabrication, the W180SGC gives you one less thing to worry about. It grips flat stock, tubing, and irregular shapes securely. Stop struggling with cheap, stamped metal clips that slip off every time you move the cable. Upgrade to a genuine Tweco steel clamp and experience the difference a solid electrical foundation makes to your welding performance.

Why Choose the W180SGC?

Tweco has been a trusted name in the welding industry for decades, known for producing high-quality guns and accessories. This 180 Amp clamp lives up to that legacy by offering professional-grade reliability at an accessible price point.

Improve your arc stability, reduce spatter caused by poor grounding, and weld with the assurance that your circuit is secure.
