The cut angle is not
square.
• Make sure that the torch is square to the workpiece.
• Check the gas pressure and the gas supply hose. See page 140.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Make sure the direction of the torch travel is correct. The best quality cut
is always on the right with respect to the forward motion of the torch.
• Make sure the cut chart parameters or the program code values are
correct. Adjust the torch-to-work distance (cut height) and the cut speed
as needed. Refer to the cut charts starting on page 121.
The torch does not
completely pierce the
workpiece, and there is
excessive sparking on
the top of the workpiece.
• Clean the metal surface of any rust, paint, or other residue that may
prevent a good metal-to-metal connection.
• Make sure that the work lead is making good contact with the cutting
table. Make sure that the cutting table is properly grounded and is making
good contact with the workpiece.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Make sure the cut chart parameters or the program code values are
correct. Try decreasing the cut speed. Refer to the cut charts starting on
page 121.
• Increase the output current (amperage) on the plasma power supply.
Seepage51.
• If the output current cannot be increased, determine if the metal being cut
exceeds the maximum capacity for this system. See Cutting specifications
on page 22.
• Inspect the torch lead. Straighten it out if it is twisted or kinked. Replace it
if it is damaged.
• Make sure the incoming gas supply hose has an internal diameter of
9.5 mm (3/8 inch) or greater.
Excessive dross forms on
the bottom of the cut.
• Check the gas pressure and the gas supply hose. See page 140.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Make sure the cut chart parameters or the program code values are
correct. Try adjusting the cut speed. Refer to the cut charts starting on
page 121.
• Increase the output current (amperage) on the plasma power supply.
Seepage51.
• Inspect the torch lead. Straighten it if it is twisted or kinked. Replace it if it
is damaged.
