Tweco WS200GC 200 Amp High Copper Alloy Work Clamp

Reliable Grounding for Superior Welds

Every welder knows that a bad ground is the root cause of many welding headaches. From sputtering starts and wandering arcs to inconsistent penetration, a poor electrical return path can ruin your bead and waste your time. The Tweco WS200GC 200 Amp High Copper Ground Clamp is built to solve these problems by providing a rock-solid connection you can trust. Unlike cheap, stamped steel clamps that rust and lose conductivity, this heavy-duty work clamp features high-quality copper alloy jaws. Copper is the gold standard for welding grounds because it conducts electricity far better than steel, ensuring that the power your machine puts out actually makes it to the arc.

Designed with the welder's daily grind in mind, the WS200GC features a powerful spring that bites down hard on your workpiece. This strong grip cuts through light rust and scale to establish a clean electrical contact instantly. The tong-style design is easy to operate with one hand, even when wearing thick welding gloves, allowing you to move your ground quickly as you work around a large assembly. Whether you are welding on a bench, repairing farm equipment, or fabricating in a shop, the versatility of the alligator-style jaw allows it to clamp onto flat plate, pipe, angle iron, and irregular shapes with ease.

Heat is the enemy of welding equipment, and ground clamps are no exception. When a clamp has poor contact or high resistance, it gets hot—sometimes hot enough to melt the cable insulation or anneal the spring, rendering the clamp useless. The high copper content of the WS200GC not only conducts electricity efficiently but also dissipates heat effectively, keeping the clamp cooler during long welding sessions. This durability means you won't be replacing your ground clamp every few months. It is an investment in smoother arcs, easier starts, and better-looking welds.

Compatible with most 200-amp welding machines, this clamp is the perfect upgrade for the flimsy stock clamps often supplied with smaller MIG and Stick welders. It is easy to install on your existing ground lead and is built to withstand the rough-and-tumble environment of a working shop. Don't let a bad ground hold you back; upgrade to the Tweco WS200GC and experience the difference a professional-grade connection makes.
