CAUTION
ELECTRIC SHOCK can kill. DO NOT TOUCH live electric parts. Disconnect input power conductors from de-
energized supply line before moving the welding power source.
WARNING
FALLING EQUIPMENT can cause serious personal injury and equipment damage.
Lift unit with handle on top of case. Use handcart or similar device of adequate capacity. If using a fork lift vehicle, place secure unit on
a proper skid before transporting.
2.06 Duty Cycle
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 10 minute duty cycle period the
following example is used. Suppose a Welding Power Source is designed to operate at a 40% duty cycle, 75 amperes at 23 volts. This
means that it has been designed and built to provide the rated amperage (75A) for 4 minutes, i.e. arc welding time, out of every 10
minute period (40% of 10 minutes is 4 minutes). During the other 6 minutes of the 10 minute period the Welding Power Source must
idle and allowed to cool.
