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, and come in two sizes: 4" to 8" and 8" to 16". Clamps attach and detach in seconds with easily adjustable tension spring and mandrel adjustment handle. Clamps utilise 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

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,” said
