WELDING CAPABILITY
The POWER WAVE 455 STT 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 outputs at lower duty cycles. For the STT process only, the machine is rated at 325 amps, 100% duty cycle.
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
COMPATIBLE LINCOLN EQUIPMENT
All Lincoln Power Feed™ Wire Feeders.
POWER SOURCE OPERATION
DUTY CYCLE AND TIME PERIOD
The POWER WAVE 455 STT 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. For the STT process only, the machine is rated at 325 amps, 100% duty cycle. A 60% duty cycle represents 6 minutes of welding and 4 minutes of idling in a ten minute period.
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 STT status light will flash green, and sometimes red and green, for up to one minute when the POWER WAVE 455 STT is first turned on. This is a normal situation as the machine goes through a self test at power up.

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.
