DUTY CYCLE AND WELDING
CAPABILITIES
The Power Feed 10 wire feeder is capable of welding
at a 100% duty cycle (continuous welding). The
power source will be the limiting factor in determining
system duty cycle capability.
The Power Wave 455 is rated 450 amps at 38 volts,
100% duty cycle, and 570 amps at 43 volts, 60%
duty cycle. On 50 Hz, the 60% rating is 500 amps at
40 volts, 60% duty cycle. The duty cycle is based
upon a ten minute period. A 60% duty cycle repre-
sents six minutes of welding and four minutes of
idling in a ten minute period.
If the duty cycle is exceeded, a thermostat will shut
off the output until the machine cools to a reasonable
operating temperature.

LIMITATIONS

• The Power Wave is not recommended for process-
es other than those listed.
• The Power Wave can only be used with Power
Feed wire feeders. Other models of Lincoln feed-
ers, or any models of non-Lincoln wire feeders,
cannot be used.

1. POWER SWITCH: Controls input power to the
Power Wave.
2. STATUS LIGHT: A two color light that indicates
system errors. Normal operation is a steady
green light. Error conditions are indicated as fol-
lows:
NOTE: The Power Wave 455 status light will flash
green, and sometimes red and green, for up to one
minute when the Power Wave 455 is first turned on.
This is a normal situation as the machine goes
through a self test at power up.
