You can google "cutmaster102" and find that info. Before you do...click on the link below to look at the Hypertherm Powermax1250. It is an 80 amp unit...compared to the cutmaster 100 amps.....but cuts at the same speeds, same thicknesses...has higher duty cycle and is much more versatile as far as input voltages go....it's circuitry automatically adjusts for any input voltage from 190 volts to 600 volts...single or 3 phase.....so during low voltage or brownouts...or operating from a generator there will be minimal affect to the cutting arc. The 1250 also features FineCut consumables that use Hypertherm's HyDef technology to provide for superior cut quality on materials thinner than 3/16". Don't just go with amperage ratings...look at the whole picture...and if you can, try one out at the local welding supply!
