Sumner Manufacturing, the industry leader in pipe and material handling equipment, announces new Rotary Internal Ground Clamp for welders.

Houston, TX - Sumner Manufacturing introduces the new Rotary Internal Ground Clamp for welders. The Rotary Internal Ground Clamp prevents ground wire tangles for welding applications that are rotating pipe by keeping the ground wire stationary as the pipe rotates.

"The most prominent feature of Rotating Internal Ground Clamps is their versatility," says Sumner's National Sales Manager, Brendan Conway. "With the positive ground and firm hold they provide, they can be used horizontally or vertically with welding applications that are manual, semi-automatic or fully automatic. And since they are brass they are ideal for use with stainless steel and stainless titanium pipe."

Rotating Internal Ground Clamps have three mandrels providing contact to the internal dimensions of a pipe come in two sizes: 4-inch to 8-inch and 8-inch to 16-inch. Clamps attach and detach in seconds with easily adjustable tension spring and mandrel adjustment handle. Clamps utilize the reliable "C" rotary ground that incorporates both a stationary and movable contact plate that rotates 360. Positive anti-arc bearings take loads up to 500 amps. Ground wires attach easily with removable ground cover and double oval-point screws.
