Duty Cycle
Rated Current
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.
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 filter-
ing capabilities.
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, depend-
ing upon choice of torch, consumables, and actual cutting operation.
