Notes
1. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is re-
duced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
2. Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause
double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting perfor-
mance and rapid electrode wear. Optional filters provide increased filtering capabilities.
NOTE
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifi-
cations include calculating an output voltage based upon power supply rated current. To facilitate com-
parison 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 cut-
ting with a TDC torch. This voltage may be more or less than IEC voltage, depending upon choice of
torch, consumables, and actual cutting operation.
