Tweco RG-230 800A Rotary Earth Clamp

Stop Wrestling with Twisted Cables

If you have ever welded a pipe spool or a tank on rollers, you know the frustration of watching your ground lead slowly wrap itself around the work. Eventually, you have to stop, unclamp, untangle the mess, and reclamp—often ruining your rhythm and wasting time. The Tweco RG-230 Roto-Ground Clamp is the industry-standard solution to this headache. It is designed to spin freely with your workpiece, keeping your cables straight and your mind on the puddle.

This isn't a lightweight hobby clamp; the RG-230 is a beast rated for 800 Amps. Whether you are running thick flux-cored wire or burning heavy stick electrodes, this rotary ground can take the heat. It features a solid copper alloy construction that transfers current smoothly, ensuring your arc doesn't sputter or wander due to a poor ground connection. The dual stud design lets you hook up your heavy leads securely, giving you confidence that you have the power you need at the torch.

Using a Roto-Ground also saves your cables. Constant twisting snaps the copper strands inside the jacket, leading to hot spots and eventual cable failure. By using the RG-230, you extend the life of your leads and improve safety in your shop. It's an essential tool for any serious pipe welder or fabricator working with positioners. Just bolt it on, hook up your ground, and weld all the way around without stopping.
