Lincoln Electric IM845 POWER WAVE 355M - Manual (Page 18)

GENERAL DESCRIPTION
The POWER WAVE ® 355M semi-automatic power
source is designed to be a part of a modular, multi-
process welding system. Depending on configuration,
it can support constant current, constant voltage, con-
stant power and pulse welding modes.
The POWER WAVE ® 355M power source is designed
to be used with the semi automatic family of Power
Feed
® wire feeders, operating as a system. Each com-
ponent 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 compo-
nents communicate with Arclink..
The POWER WAVE ® 355M is a high performance,
digitally controlled inverter welding power source
capable 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 ® 355M can be set up in a number
of configurations, some requiring optional equipment
or welding programs. Each machine is factory prepro-
grammed with multiple welding procedures, typically
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 ® 355M is recommended for semi-
automatic welding, and may also be suitable for basic
hard automation applications.
• This Power Wave ® is not recommended for process-
es other than those listed.

SAFETY PRECAUTIONS
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 com-
bustibles.
-------------------------------------------------------------
ARC RAYS can burn.
• Wear eye, ear, and body protection.
Observe additional guidelines detailed in the
beginning of this manual.
