Common cutting issues
Problem Solutions
The arc does not transfer to the
workpiece. • Clean the area where the ground clamp contacts the workpiece to
ensure a good metal-to-metal connection.
• Inspect the ground clamp for damage, and repair as necessary.
• The pierce-height distance may be too large. Move the torch closer to
the workpiece and fire the torch again.
The arc blows out, but re-ignites when
the torch trigger is pressed again. • Inspect the consumable parts and replace them if they are worn or
damaged. See Inspect the plasma torch consumables on page 60.
• Replace the air filter element in the back of the plasma supply if it is
contaminated. See page 114.
The cut quality is poor. • Make sure the torch is being used correctly. Refer to the Hand Cutting
or Mechanized Cutting section in the Powermax125 Operator Manual .
• Inspect the consumables for wear and replace as necessary. See
Inspect the plasma torch consumables on page 60.
• Make sure the cutting mode switch is in the proper position for the
cutting operation.
• Make sure the correct consumables are installed.
