A NOTE ON BACK BEVELING
Remove the torch from the torch carrier assembly. Rotate the Torch Clamp Base and Torch 180 degrees on the Torch Arm and
re-tighten with thumbscrew and clamp. Reinstall the torch into the torch carrier assembly. When back beveling, place Torch as
close to Saddle as possible without placing flame directly on or near Saddle. The Torch is now positioned for back beveling.
WARNING: When back beveling, the cutting flame and “hot” zone of the pipe is directed toward
the operator.
WARNING: The pipe and debris from the cutting process are extremely hot and can cause serious
injury.
WARNING: Keep hands and clothing away from the gearing as it will cause serious injury.
