The Power Wave semi-automatic power source is
designed to be a part of a modular, multi-process weld-
ing system. Depending on configuration, it can support
constant current, constant voltage, and pulse welding
modes.

The Power Wave power source is designed to be used
with the semi automatic family of Power Feed wire
feeders, operating as a system. Each component in
the system has special circuitry to "talk with" the other
system components, so each component (power
source, wire feeder, user interface) knows what the
other is doing at all times. These components commu-
nicate with Linc-Net.

The POWER WAVE 355/405 is a high performance,
digitally controlled inverter welding power source capa-
ble of complex, high-speed waveform control. Properly
equipped, it can support the GMAW, GMAW-P, FCAW,
SMAW, GTAW, and CAC-A processes. It carries an
output rating of 350 Amps, 34 Volts at 60% duty cycle
and 300 Amps, 32 volts at 100% duty cycle.

RECOMMENDED PROCESSES AND
EQUIPMENT

RECOMMENDED PROCESSES

The POWER WAVE 355/405 can be set up in a num-
ber of configurations, some requiring optional equip-
ment or welding programs. Each machine is factory
preprogrammed with multiple welding procedures, typ-
ically including GMAW, GMAW-P, FCAW, GTAW, and
CAC-A for a variety of materials, including mild steel,
stainless steel, cored wires, and aluminum.

The POWER WAVE 355/405 is recommended for
semi-automatic welding, and may also be suitable for
basic hard automation applications.

• This Power Wave is not recommended for processes

other than those listed.

SAFETY PRECUATIONS

Read this entire section of operating instructions
before operating the machine.

ELECTRIC SHOCK can kill.

• Unless using cold feed feature, when

feeding with gun trigger, the elec-
trode and drive mechanism are
always electrically energized and
could remain energized several sec-

onds after the welding ceases.

• Do not touch electrically live parts or electrodes

with your skin or wet clothing.

• Insulate yourself from the work and ground.

• Always wear dry insulating gloves.

-----------------------------------------------------------

FUMES AND GASES can be dangerous.

• Keep your head out of fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

-----------------------------------------------------------

WELDING SPARKS can cause fire or
explosion.

• Keep flammable material away.

• Do not weld on containers that have

held combustibles.

-----------------------------------------------------------

ARC RAYS can burn.

• Wear eye, ear, and body protection.

Observe additional guidelines detailed in the
beginning of this manual.
