Note 1. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is reduced
if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
Note 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 performance
and rapid electrode wear. Optional filters provide increased filtering capabilities.

NOTE
IEC Rating is determined as specied by the International Electro-Technical Commission. These specications 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.
CW Rating is determined using an output voltage representative of actual output voltage during cutting with a Cigweld torch.
This voltage may be more or less than IEC voltage, depending upon choice of torch, consumables, and actual cutting operation.
NOTE
In gouging mode, the maximum output current is limited to 50A.
