2.4 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 30% duty cycle, 80 amperes at 23.2
volts. This means that it has been designed and built to provide the rated
amperage (80A) for 3 minutes, i.e. arc welding time, out of every 10 minute
period (30% of 10 minutes is 3 minutes). During the other 7 minutes of the 10
minute period the Welding Power Source must idle and allowed to cool.
Duty cycle is percentage of 10 minutes that unit can weld at rated
load without overheating.
Exceeding duty cycle can damage unit and void warranty.

2.5 Transportation Methods

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.
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.

3.1 Selecting a Location

Be sure to locate the welder according to the following guidelines:
• In areas, free from moisture and dust.
• Ambient temperature between 32°F (0°C) to 104° F (40° C).
• In areas, free from oil, steam and corrosive gases.
• In areas, not subjected to abnormal vibration or shock.
