The cut quality is
unsatisfactory, or
the cut does not
sever the
workpiece.
The cartridge is
worn, the work lead
connection is not
satisfactory, the
output from the
plasma power supply
is too low, the power
PCB is supplying
low current, or the
selected operating
mode is not correct.
• The cartridge is worn.
• Examine the Hypertherm cartridge.
Replace it if it is worn or has
damage. A higher rate of 0-30-0
faults is typical as a cartridge gets
near end-of-life.
• There is not a good
connection between the
work clamp and the
workpiece.
• The workpiece is dirty.
• There is damage to the
work clamp or to the
work lead.
• If possible, move the work clamp
closer to the area of the workpiece
you are cutting.
• Clean the area where the work
clamp comes into contact with the
workpiece or cutting table. Remove
any rust, paint, or other residue.
Make sure that there is good
metal-to-metal contact.
• Examine the work clamp for damage.
Repair or replace it if necessary.
• Make sure that the cutting table is
correctly grounded and has good
contact with the workpiece.
• The output current (A) is
set too low.
• Increase the output current (A) as
necessary.
• The operating mode
setting on the plasma
power supply is not
correct for the cutting
application.
• If you are in basic mode, make sure
that the Hypertherm cartridge aligns
with the operating mode. Use a
gouging cartridge in Gouge mode.
Use a cutting cartridge in Cut mode
or Expanded Metal mode. For more
information on basic mode, refer to
• An extension cord is not
sufficient for the system.
• Operate the plasma power supply
without using an extension cord. If
you must use an extension cord, use
a heavy conductor cord of the
shortest possible length.
• The pilot arc IGBT is
defective.
• The power PCB is
defective.
