POWER WAVE 355M
POWER WAVE 355M – Semi-Automatic Operation
Power Wave 355M can only be used with ArcLink
compatible Power Feed M semi-automatic wire feed-
ers. In addition, the Power Feed semi-automatic wire
feeders may require optional equipment to access
certain weld modes in the Power Wave. Other models
of Lincoln feeders, or any models of non-Lincoln wire
feeders, cannot be used.
All welding programs and procedures are selected
through the Power Feed M semi-automatic user inter-
face
REQUIRED EQUIPMENT
Any ArcLink compatible semi-automatic wire feeding
equipment. Specifically, the semi-automatic Power
Feed M family.
LIMITATIONS
• Only ArcLink compatible Power Feed M semi-
automatic wire feeders and users interfaces may be
used. Other Lincoln wire feeders or non-Lincoln wire
feeders cannot be used.
• POWER WAVE 355M Output Limitations
The POWER WAVE 355M will support maximum
average output current of 350 Amps @ 60% duty
cycle.
DUTY CYCLE AND TIME PERIOD
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 period.
CASE FRONT CONTROLS
All operator controls are located on the case front of
the Power Wave. (See Figure B.1)
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, per
Troubleshooting E Section in this Manual.
NOTE: The POWER WAVE 355M status light will
flash green, and sometimes red and green, for up to
one minute when the machine 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 and the
fan continues to run, until the machine cools down.
When cool, the light goes out and output is
enabled.
4. CB1 WIRE FEEDER CIRCUIT BREAKER:
Protects 40 volt DC wire feeder power supply.
