Duramax Retrofit Torch
Operator Manual
3-27
The cut angle is not square. Causes can be:
• The torch is not square to the workpiece.
• The consumables are worn and need to be replaced. For optimized performance in a mechanized application,
replace the nozzle and the electrode together.
• The direction of the torch travel is incorrect. The high-quality cut is always on the right with respect to the
forward motion of the torch.
• The distance between the torch and the workpiece is not correct.
• The cutting speed is not correct. See “Using the cut charts” on page 3-2 for more information.
The consumables’ life is shortened. Causes can be:
• The arc current, arc voltage, travel speed, and other variables are not set as recommended in the cut charts.
• Firing the arc in the air (beginning or ending the cut off of the plate surface). Starting at the edge is acceptable
as long as the arc makes contact with the workpiece when started.
• Starting a pierce with an incorrect torch height. Refer to the cut charts for the specific initial pierce height.
