The UNITIG 200 AC/DC is a 240V square wave AC/DC TIG inverter welder incorporating full TIG functionality including AC balance control, pre gas, down slope, post gas, variable pulse parameters, HF start with 2/4T trigger control.

  • The HF arc start provides easy arc ignition leaving no tungsten inclusion and no contamination of the tungsten electrode.
  • The Down Slope and Post Gas combined with the 2/4T trigger function gives you control of the welder allowing you to control the start and finish of the weld process at a professional level.
  • The addition of a fully adjustable pulse function of frequency, base current and pulse width gives you the added capability to better control heat input into the work, control penetration & control distortion.
  • AC balance control lets you set the AC TIG arc for cleaning of the oxide layer on aluminium and adjustment for a deeper penetrating weld.
  • Combining the functions of the UNITIG 200 AC/DC ensures comprehensive control of the welding parameters when welding both AC and DC weldable materials giving you the ability to produce professional TIG welds.
  • The DC MMA welding capability delivers a smooth and stable arc allowing easy welding with electrodes obtaining high quality welds including cast Iron, stainless steel and low hydrogen.
  • Addition of the optional Foot Control provides variable amperage adjustment during welding.
  • The UNIMIG 200 AC/DC has set the benchmark for 240V single phase AC/DC welders and made it ideal for multiple applications including aluminium & stainless steel fabrication, light industrial use, repair and maintenance applications.
