Back-beveling can also be achieved by using an angle head attachment on the cutting torch. An angle head attachment allows the cutting tip to be positioned to different bevel angles independent of the torch. The torch remains vertical and the angle head attachment pivots the cutting tip to different angles. Set the machine on the pipe as in normal cutting procedures and begin the back-beveling operation. Position the cutting tip as far back from the ring gear as possible when back-beveling.
Excess heat placed on the ring gear during back-beveling can damage the machine.
