NOTE:
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifications
include calculating an output voltage based upon power supply rated current. To facilitate comparison between
power supplies, all manufacturers use this output voltage to determine duty cycle.
TDC Rating is determined using an output voltage representative of actual output voltage during cutting with a
TDC torch. This voltage may be more or less than IEC voltage, depending upon choice of torch, consumables, and
actual cutting operation.
