OVERVIEW

Reliable Grounding for Industrial Welding

The ESAB RT-250 Earth Device is a critical component for maintaining a high-quality welding circuit. In any arc welding process, the quality of the ground connection is just as important as the welding torch or electrode holder. A poor ground can lead to unstable arcs, wandering puddles, excessive spatter, and even damage to the welding machine due to voltage spikes. The RT-250 is engineered to provide a secure, low-resistance connection to the workpiece, ensuring that the full welding current is delivered to the arc efficiently.

Rated for 250 Amps, this earth device is suitable for a wide range of light to medium-duty industrial applications, including general fabrication, maintenance, and repair work. It is constructed from high-grade materials that offer excellent electrical conductivity and resistance to heat buildup. The robust design ensures that the clamp maintains a firm grip on the workpiece, even when attached to irregular shapes or slightly corroded surfaces (though cleaning the surface is always recommended). By minimizing resistance at the contact point, the RT-250 helps prevent the clamp itself from overheating, extending the lifespan of both the accessory and the welding cable.

For industrial facilities and MRO operations, reliability is key. The ESAB RT-250 is built to withstand the rigors of the shop floor. Its mechanism is designed for easy operation, allowing welders to quickly attach and detach the ground lead as they move between workpieces. Whether used with Stick, MIG, or TIG welding power sources, this earth device provides the consistent performance required for code-quality welds. Investing in quality grounding accessories like the RT-250 is a cost-effective way to improve overall welding efficiency and reduce downtime caused by equipment troubleshooting.

FAQ

The RT-250 is rated for a maximum welding current of 250 Amps.

It is suitable for Stick (SMAW), MIG (GMAW), and TIG (GTAW) welding processes within the 250A limit.

A good ground clamp reduces electrical resistance, preventing voltage drops that cause unstable arcs, hard starts, and excessive spatter.

Yes, as long as the welding machine's output does not exceed 250 Amps and the cable lug fits the clamp's connection point.

No, this is typically sold as the clamp device only. You will need to attach it to your existing welding ground cable.

The contact points are typically made of a copper alloy or brass to ensure high electrical conductivity.

For the best connection, you should always grind off paint, rust, or scale where the clamp attaches. However, a strong clamp can sometimes bite through thin layers.
