5 – Troubleshooting and System Tests
The circuit breaker trips
frequently while you are
cutting. • The output from the
power supply is too
high.
• The wrong
consumables are
being used.
• The power supply is
not receiving enough
input power.
• The operator is
stretching the arc
while cutting.
• The extension cord is
not delivering
sufficient power to the
power supply.
• The amperage
adjustment knob is set
too high for the input
circuit.
• The general-purpose
nozzle and shield are
being used with an
input circuit of
120 VAC.
• The input circuit is not
delivering sufficient
power to the power
supply.
• The operator is holding
the torch too far from
the workpiece when
cutting.
• The extension cord is
too long, is damaged,
or is not capable of
delivering sufficient
power to the power
supply.
• Turn down the cutting current.
See Adjust the gas pressure
and output current on page 44.
• Use only the FineCut
consumables when operating
the system on a 120 VAC input
circuit. See
Choose the
consumables on page 32.
• Operate the system on a
240 VAC input circuit
whenever possible.
• Avoid stretching the arc. Drag
the torch on the workpiece. See
Edge start on a workpiece on
page 50.
• Operate the system without
using an extension cord. If you
must use an extension cord,
use a heavy conductor cord of
the shortest possible length.
See
Extension cord
recommendations on page 28.
• Verify nothing else is drawing
power on the same circuit.
