Lincoln Electric IM718 manual General Description, Recommended Processes and Equipment

B-4 OPERATION B-4

GENERAL DESCRIPTION

The Power Wave AC/DC power source is designed to be a part of a modular welding system. Each welding arc may be driven by a single machine or by a number of machines in parallel. Additionally with the use of an external Phase Generator the phase angle and fre- quency of different machines can be synchronized.

The Power Wave AC/DC is a high performance, digi- tally controlled inverter welding power source capable of complex, high-speed waveform control. The Power Wave AC/DC is capable of producing a variable fre- quency and amplitude AC output, a DC positive out- put, or a DC negative output. The Power Wave AC/DC can support constant current, constant voltage and pulse welding modes.

The Power Wave AC/DC is designed to communicate with other Arc-Link equipment. Additionally it can com- municate with other industrial machines via DeviceNET. Also the Power Wave AC/DC machines are capable of communicating by Ethernet. The result is a highly integrated and flexible welding cell.

RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

The Power Wave AC/DC 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 SAW, GMAW, GMAW-P, FCAW, GTAW for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum. It carries an output rating of 500 amps, 44 volts (at 100% duty cycle).

The Power Wave AC/DC can be configured for robot- ic, hard-automation or semi-automatic use.

PROCESS LIMITATIONS

The Power Wave AC/DC is suitable only for the processes listed.

RECOMMENDED EQUIPMENT /INTERFACE

Robotic Operation

All welding programs and procedures are configured through software for the robotic Power Waves. With the proper configuration, Fanuc robots equipped with RJ-3 or RJ-3iB controllers may communicate directly to the Power Wave via ArcLink or DeviceNet. Proper configuration and options allow other equipment such as PLC’s or computers to interface with a Power Wave through a serial, DeviceNet, ArcLink, or Ethernet interfaces. All wire welding processes require a robotic Power Feed wire feeder.

Hard Automation

Operating the Power Wave AC/DC in a hard automa- tion application requires a PC or PLC for the user interface. The power source communicates with the PC via Ethernet. A wire feeder can be controlled through Arc-link, DeviceNET or Ethernet.

SemiAutomatic Operation

Operating the Power Wave AC/DC in the semi-auto- matic mode requires an Arc-Link compatible wire feeder and user interface.

EQUIPMENT LIMITATIONS

•The Power Waves are not to be used in outdoor environments.

•Only Arc-Link Power Feed wire feeders may be used with standard interfaces. Other Lincoln wire feeders or non-Lincoln wire feeders can only be used with custom interfaces.

•Operating Temperature Range is –20C to + 40C.

•The Power Wave AC/DC will support a maximum average output current of 500 Amps at 100% Duty Cycle.

REQUIRED EQUIPMENT

•Control Cables (22 pin to 22 pin), K1795-10,-25,-50,-100

•Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 10 ft), K1804-1

•Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 18 in), K1805-1

•Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 18 in), K1804-2

DUTY CYCLE AND TIME PERIOD
