Understand duty cycle to prevent overheating
Duty cycle – Percentage of time during a 10-minute interval that a plasma arc can remain on
without causing the system to overheat.
When you exceed the duty cycle and the system overheats:
 The plasma arc shuts off.
 The Temperature LED illuminates.
 The cooling fan inside the power supply runs.
When the system overheats:
a. Leave the system on to allow the fan to cool the power supply.
b. Wait for the Temperature LED to turn off before you start to cut again.
Stretching the plasma arc for
prolonged periods negatively
impacts duty cycle. Whenever
possible, drag the torch on the
workpiece. See Start a cut from
the edge of the workpiece on
page 67.
If you operate the system on a
lower rated electrical service,
stretching the plasma arc for
prolonged periods can cause the
system to overheat more quickly
and can cause the circuit breaker
to trip. See Decrease output
current and arc stretch for lower
rated electrical service on
page 31.
