Extension cord recommendations
Use an extension cord that meets these requirements:
 Wire gauge is approved for the cord length and plasma power supply voltage
 Complies with national and local codes

Extension cords can cause the plasma power supply to receive less input
voltage than the output of the circuit. This can limit the cut capacity of your
plasma power supply.
The tables that follow give the recommended gauge sizes for different cord lengths and input
voltages.
Use a generator (if necessary)
When you use a generator, make sure that you:
 Only use a generator that meets Hypertherm plasma power supply ratings on page 19.
 Adjust the output current (A) if necessary related to the rating, age, and condition of the
generator. Refer to Adjust the operating settings manually on page 57.
 A 10 kW generator is recommended for cutting when a full arc stretch is necessary, such as
for many gouging applications. These generators let spikes in input current occur when you
stretch the plasma arc.
 If a fault occurs, set the power switch on the plasma power supply to OFF (O). Wait
approximately 1 minute before you set the power switch to ON (I).
