WELDING CAPABILITY
The POWER WAVE 455 is rated at 60 Hz. 450A@
38V. 100% duty cycle or 570A@ 43V 60% duty cycle -
50 Hz. 400A@ 36V, 100% duty cycle or 500A@40V
60% duty cycle. The machine is capable of higher out-
puts at lower duty cycles.
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, can-
not be used.
COMPATIBLE LINCOLN EQUIPMENT
All Lincoln Power Feed™ Wire Feeders.
POWER SOURCE OPERATION
DUTY CYCLE AND TIME PERIOD
The POWER WAVE 455 is rated at 60 Hz. 450A@
38V. 100% duty cycle or 570A@ 43V 60% duty cycle -
50 Hz. 400A@ 36V, 100% duty cycle or 500A@40V
60% duty cycle. The duty cycle is based upon a ten
minute period. A 60% duty cycle represents 6 minutes
of welding and 4 minutes of idling in a ten minute peri-
od.
OPERATION
CASE FRONT CONTROLS
All operator controls and adjustments are located on
the case front of the Power Wave.
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 follows:
NOTE: The Power Wave 455 status light will flash
green, and sometimes red and green, for up to one

3. HIGH TEMPERATURE LIGHT (thermal overload):
A yellow light that comes on when an over temper-
ature situation occurs. Output is disabled until the
machine cools down. When cool, the light goes
out and output is enabled.
4. 10 AMP WIRE FEEDER CIRCUIT BREAKER:
Protects 40 volt DC wire feeder power supply.
5. 10 AMP AUXILIARY POWER CIRCUIT BREAK-
ER: Protects 110 volt AC case front receptacle
auxiliary supply.
