Welding system module allows welding process customization - TheFabricator.com

The Lincoln Electric Co. has introduced the Power Wave® Advanced module with AC welding capability to run aluminum processes.

The welding system module performs several processes: SMAW, GMAW, pulsed GMAW, GTAW, and Surface Tension Transfer® (STT®). STT is a controlled GMAW short-circuit transfer process that uses current controls to adjust the heat independent of wire feed speed. The STT capability allows the module to weld open root gaps with high-frequency inverter technology.

The high-frequency starting mode can be controlled at the wire feeder or power source user interface. The careful use of high-frequency starting can improve the appearance of GTAW arc starts and helps to reduce contamination caused by scratch starts, the company says.
