Common hand-cutting faults
The torch sputters and hisses, but does not produce an arc. The cause can be:
• The consumables are too tight. Loosen the consumables about 1/8th of a turn and try again. Never tighten the
consumables beyond just finger-tight.
The torch does not cut completely through the workpiece. The causes can be:
• The cut speed is too fast.
• The consumables are worn.
• The metal being cut is too thick.
• Gouging consumables are installed instead of cutting consumables.
• The work clamp is not attached properly to the workpiece.
• The gas pressure or gas flow rate is too low.
Cut quality is poor. The causes can be:
• The metal being cut is too thick.
• The wrong consumables are being used (gouging consumables are installed instead of cutting consumables, for
example).
• You are moving the torch too quickly or too slowly.
The arc sputters and consumables life is shorter than expected. The cause can be:
• Moisture in the gas supply.
• The gas pressure is too low.
How to use the machine torch
Since the Powermax45 and the T45m can be used with a wide variety of cutting tables, track burners, pipe bevelers,
and such, you will need to refer to the manufacturer’s instructions for specifics on operating the machine torch in
your configuration. However, the information in the following sections can help you optimize cut quality and maximize
consumable life.
Ensure the torch and table are set up correctly
• Use a square to align the torch at right angles to the workpiece.
• The torch may travel more smoothly if you clean, check, and “tune” the rails and drive system on the cutting table.
Unsteady machine motion can cause a regular, wavy pattern on the cut surface.
• Ensure that the torch does not touch the workpiece during cutting. Contact with the workpiece can damage the
shield and nozzle and affect the cut surface.
