Generator considerations

There are various considerations when you use a generator.

  • Only use a generator that meets the requirements for Hypertherm® cutting systems. Refer to Hypertherm plasma power supply ratings.
  • Adjust the output current (A) if necessary related to the rating, age, and condition of the generator.
  • 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 one minute before you set the power switch to ON (I).

Generators used with this system must meet the voltage requirements in this table.

Engine drive rating Plasma power supply output current Performance (arc stretch)
