 a inverter welder in a modern edition. It allows TIG AC/DC and MMA AC/DC welding with current up to 320A. The device is powered from a 400V three-phase network.

Thanks to the solutions used, the ProTIG 321P AC/DC also enables advanced TIG AC and TIG DC welding with a choice of arc ignition HF or Lift method. The device is equipped with a pulse welding function, which makes the machine perfect for welding very thin sheets and aluminum.

ProTIG 321P AC/DC has functions supporting the welding process in TIG method:

  • output AC waveforms: square, sinusoidal, triangular,
  • 2T/4T Trigger Control,
  • AC balance, AC frequency, pulse frequency, pulse width and pulse amps adjustment,
  • up slope and down slope adjustment,
  • SPOT welding.

ProTIG 321P AC/DC enables MMA AC and MMA DC welding. The process of joining metals in this method is additionally supported by functions such as:

  • Arc Force
  • Hot Start.

Additionally the device has 10 memory channels. The user can easily save and recall the most used settings.

Modern design, LCD function panel and the possibility of wireless control in combination with high-class components makes the ProTIG 321P AC/DC stand out on the market.
The professional device of the SPARTUS® Pro line is perfect suited to the production sector and industry.
