2 – Power Supply Setup
Extension cord recommendations
Any extension cord must have an appropriate wire size for the cord length and system voltage. Use a cord that meets
national and local codes.
For all Powermax125 configurations, the recommended gauge size for any three-phase extension cord between
3 – 45 m (10 – 150 feet) is 10 mm
2 (8 AWG).
Engine-driven generator recommendations
Generators used with the Powermax125 should satisfy the voltage requirements in the following table and in Hypertherm
power supply ratings on page 22.
 Based on the generator rating, age, and condition, adjust the cutting current as needed.
 If a fault occurs while using a generator, turning the power switch quickly to OFF and then
to ON again (sometimes called a “quick reset”) may not clear the fault. Instead, turn OFF
the power supply and wait 60 to 70 seconds before turning it ON again.
