CB-3 / CB-3H

Increase Production for Single Pass, Square or Beveled Hole Cuts with the CB-3/CB-3H Circle Burner

The CB-3 Circle Burner uses the oxy-fuel cutting process for single pass, square or beveled hole cuts. It is designed for use on vessels, large diameter pipe, domed heads and flat plate. The CB-3 includes a 2-hose oxy-fuel machine torch, adjustable tip adapter, variable speed rotation, vertical and horizontal torch adjustment and rise and fall cam. The CB-3 must be mounted on a column and boom, manipulator or fixture.

The CB-3H Circle Burner has the same features as the CB-3 and includes a hillside kit. This hillside kit is for single rise and fall motion per revolution of the machine to provide the motion required to follow the contour of an offset pipe-to-pipe weld.
