Extension cord recommendations
Use an extension cord of an appropriate wire gauge for the cord length and system voltage. Use a cord that meets
national and local codes.
 Extension cords can cause the machine to receive less input voltage than the output of
the circuit. This can limit the operation of your system.
Generator recommendations
Generators used with this system should produce 240 VAC.
 Adjust the cutting current as needed based on the generator rating, age, and condition.
 If a fault occurs while using a generator, turn OFF the system and wait approximately
60 seconds before turning it ON again. Turning the power switch quickly to OFF and
ON again (called a “quick reset”) may not clear the fault.
