Duty Cycle for 350

WeldSkill 350 Welding Current (amps)

The rated duty cycle of a Welding Power Source, is a statement of the time it may be operated at its rated 

welding current output without exceeding the temperature limits of the insulation of the component parts.  To 

explain the 0 minute duty cycle period the following example is used.  Suppose a Welding Power Source is 

designed to operate at a 30% duty cycle, 350 amperes at 3.5 volts.  This means that it has been designed and 

built to provide the rated amperage (350A) for 3 minutes, i.e. arc welding time,  out of every 0 minute period 

(30% of 0 minutes is 3 minutes).  During the other 7 minutes of the 0 minute period the Welding Power 

Source must idle and be allowed to cool. The thermal cutout will operate if the duty cycle is exceeded.
