Recommended torch-pivot lengths

The bevel-pivot point
point is the intersection of the torch axis and the top of the workpiece when the torch is at its
maximum angle and minimum clearance.
The use of extreme bevel consumables increases the recommended torch-pivot length by more than
100%. Refer to Figure 1

Clearance

Clearance
Clearance is the minimum distance between the torch and the top of the workpiece. A higher

clearance can decrease the chance of torch collisions with the workpiece. But, it can also cause the
following conditions:
Increased cut heights that give bad edge quality and make higher-angle compensations

necessary
Increased voltages that can have a bad effect on the duty cycle of the plasma power supply
