WE02100427 - ESAB RT-250 Welding Ground Clamp 250A

Stabilize Your Arc with the ESAB RT-250

Every welder knows that a good weld starts with a good ground. The ESAB RT-250 Earth Device is a 250-amp ground clamp designed to give you the solid connection you need for smooth, consistent welding. If you have ever struggled with an arc that sputters, cuts out, or wanders, your ground clamp is often the culprit. Old, worn-out clamps with weak springs or corroded contacts create resistance, robbing your arc of power and generating excess heat. The RT-250 solves this problem with a heavy-duty design that bites hard and stays cool.

This clamp is perfect for the garage, the farm, or the fab shop. With a 250A rating, it handles most standard MIG and Stick welding jobs with ease. The contact points are designed to maximize surface area on the metal, ensuring efficient current transfer. This means you get instant arc starts and a stable puddle control, which is essential for producing professional-looking beads. The clamp is also easy to install on your existing welding leads, making it a quick upgrade that delivers immediate results.

Durability is a standout feature of the ESAB RT-250. Welding environments are tough—clamps get dropped, dragged, and exposed to sparks and slag. ESAB has engineered this device to hold up under pressure. The spring or screw mechanism (depending on the specific sub-variant of the RT series) is built to retain its tension over time, ensuring you don't lose grip halfway through a project. Don't let a cheap ground clamp ruin your work; upgrade to the ESAB RT-250 and experience the difference a solid electrical foundation makes for your welding projects.
