Pulsed DC TIG inverter
- Published: March 14, 2018
ESAB Welding & Cutting Products has announced that the Renegade ET 300iP DC TIG/Stick inverter, which features controls for pulsed TIG welding and high frequency (HF) or Lift TIG arc starts options, is now in stock and ready to ship in the U.S. and Canada.
ESAB previewed the unit at FABTECH 2017 n November (view video here).
The Renegade ET 300iP produces a top output of 300 amps at 40% duty cycle, weighs 37 lbs and measures 12.6 x 7.8 x 18.11 in. It connects to 230 V 1-phase power and 230 V to 480 V 3-phase power (±10 percent) with auto-sensing functionality and no rewiring required. It has a pulse frequency adjustable up to 999 pulses per second (PPS) and a peak pulse width (or duration) adjustable between 10 and 90%. Pulsed TIG welding can be used to improve weld puddle control, control the weld bead profile, reduce heat input and increase travel speeds.
“Renegade ET 300iP enables tailoring the pulsed DC TIG welding arc to the application, which is especially useful when welding thin material and working on applications such as stainless steel pipes in the food, process piping and mechanical contracting industries,” says Doug Smith, product business manager – Light/Industrial Arc Equipment, ESAB.
The unit features an intuitive digital readout display that makes it easy to set parameters and read them from a distance in any light, while a remote amperage control with digital display extends operator range by providing extreme accuracy over long distances. Renegade ET 300iP also provides adjustable gas pre- and post-flow, adjustable upslope/downslope, 2- and 4-stroke trigger functionality, offers a remote foot pedal compatibility and includes a water-cooled option. It converts from a water-cooled system to an air-cooled portable system in minutes, and conversion does not require tools.
