Tweco WCRG-1200 Rotary Ground Clamp 1200A

Stop Fighting Twisted Cables

If you have ever welded pipe or tanks on a positioner, you know the frustration of watching your ground lead slowly wrap itself around the workpiece. One minute you are laying down a perfect bead, and the next, your cable snaps tight, pulling on your feeder or, worse, breaking the connection entirely. The Tweco WCRG-1200 Roto-Work Clamp is the ultimate solution to this headache. Designed specifically for rotating weldments, this "Roto-Ground" allows your work to spin endlessly while your ground cable stays perfectly still and relaxed on the floor.

This isn't just a swivel; it is a heavy-duty electrical connector capable of pumping 1200 Amps of welding current. Whether you are running hot Sub-Arc passes or heavy Flux Core wire, the WCRG-1200 can take the heat. It features a rugged copper construction that ensures you get a solid, consistent ground every time you strike an arc. A poor ground on a rotating piece can cause arc wander and sputtering, ruining your weld quality. The Tweco Roto-Ground eliminates that variable, giving you the smooth, stable arc you need for X-ray quality welds.

The WCRG-1200 is built to survive the shop environment. It uses a dual-head design to spread the current load, which keeps the unit cooler and extends its service life. Setting it up is easy—simply mount it to your fixture or the end of your pipe stand, bolt on your ground lead, and you are ready to roll. No more stopping every few passes to untangle the mess. No more damaged cables. Just continuous, hassle-free welding.
