All-process, inverter-based welding system is first of its kind

ESAB Welding & Cutting Products has introduced the Rebel™ EMP 205 AC/DC, which the company says is the first true all-process, inverter-based welding system. Users can perform GTAW with AC and DC outputs, GMAW with solid wires (steel, stainless, or aluminum), FCAW with gas-shielded and self-shielded wires, and SMAW with a DC output. The rated duty cycle is 205 amps at 20 percent.

AC output frequency controls the shape of the arc cone and arc force, while wave balance controls the amount of cleaning action versus penetration. HF, or noncontact, arc starts are required for aluminum and are desirable (and sometimes required) in applications in which end users want to prevent accidental contamination from the tungsten electrode.

Commercial availability is expected in Q2 2018.
