System operation guidelines
 To achieve the highest level of performance:
 Operate the system at an input power of 240 VAC whenever possible.
 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 28.
 If you are operating your system on a 120 V, 15 A circuit, do not set the amperage higher than 20 A. See Voltage
configurations on page 25.
 For best results when operating your system on a 120 V, 15 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 with the general-purpose (standard) consumables 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 25.
 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 50.
