ESAB Renegade 300iP enables pulsed DC GTAW arc tailored to the application

ESAB Welding & Cutting Products has introduced the Renegade™ ET 300iP DC GTAW/SMAW inverter, which features controls for pulsed GTAW and HF or Lift TIG arc start options.

The unit produces a top output of 300 amps at 40 percent duty cycle, weighs 37 lbs., and measures 12.6 by 7.8 by 18.11 in. It connects to 230-V, one-phase power and 230-V to 480-V, three-phase power (±10 percent) with autosensing functionality and no rewiring required.

It has a pulse frequency adjustable up to 999 pulses per second and a peak pulse width (or duration) adjustable between 10 and 90 percent. Pulsed GTAW can be used to improve weld puddle control, control the weld bead profile, reduce heat input, and increase travel speeds.
