4–Operation
System operation guidelines
 To achieve the highest level of performance:
 Operate the system at an input power of 240 VAC whenever possible.
 Do not operate the system on a 120 V / 15 A circuit.
 Avoid using an extension cord whenever possible.

If you must use an extension cord, use a heavy conductor cord of the shortest possible
length. See Extension cord recommendations on page 31.
 If you are operating your system on a 120 V / 20 A circuit, do not set the amperage higher than 20 A. See Voltage
configurations on page 27.
 For best results when operating your system on a 120 V / 20 A circuit:
 Do not connect anything else that will draw power from the same circuit.
 Be aware that extension cords can reduce the voltage to the machine from what is output by the circuit. This
reduction in power can impair cutting performance and increase the probability of tripping the circuit breaker.
 Cutting a thicker workpiece requires a higher amperage setting. It is preferable to operate on a higher rated circuit
(240 V / 30 A) when cutting thicker metal. See Voltage configurations on page 27.
 Additional techniques to reduce the frequency of tripped circuit breakers include:
 Turn down the amperage adjustment knob.
 Avoid stretching the arc. Instead, drag the torch on the workpiece as explained in Edge start on a workpiece on
page 52.
 When you operate the system at altitudes higher than 2,200 m (7,500 feet) above sea level, you may experience
some reduction in cutting performance due to the adverse effect that altitude has on the internal air compressor.
