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 combustibles.

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

ARC RAYS can burn.

• Wear eye, ear, and body protection.

Observe additional guidelines detailed in the beginning of this manual.

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, constant 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 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 Arclink..

The POWER WAVE 355M is a high performance, dig- itally 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 car- ries 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 processes other than those listed.
