  • High efficiency, 2 - 3 times the efficiency of DC TIG

  • Adjustable TIG parameters (pre-gas/post-gas, up-slope/down-slope, arc stating/stopping, peak/base current, duty cycle/ frequency)

  • 2-step, 4-step, repeat and spot welding operation modes

  • Water-cooled and gas-cooled TIG welding torch can be selected

  • Complete automation equipment interface: current and voltage output signal, successful arc starting signal, welding machine starting signal, current setting signal and gas test signal; digital communication interface can be selected [RS485, etc.]

  • The hot wire power supply can be switched between AC and DC; Parameters are adjustable (heating current / AC frequency)

  • All power supplies adopt full-bridge inverter soft switch control technology, double IGBT modules, quick recovery diode module; IGBT modules are adopted for the secondary inverter of hot wire power supply

  • PCB is processed by three-proofing lacquer; the drive board is processed with waterproof rubber

  • It enjoys IP23 class protection and H class insulation

  • Protection against overheat, over-current, over-voltage, short circuit, lack of coolant and welding torch switch short-circuiting; error code display


  • Gas-test / wire-test function

  • Wire feeding/ wire drawing function

  • Hot wire and cold wire can be applied

  • Constant speed wire feeding, pulse wire feeding, and pulse synchronized wire feeding [match the pulse rate of ATIG400P(HW) welding machine]

  • Digital wire feeder brings adjustable wire feeding parameters: wire feeding/stopping delay time, high speed wire feeding time/speed, low speed wire feeding time/speed, wire drawing time;

  • Closed type wire feeding mechanism, 4-roller drive + encoder feedback ensure stable and robust wire feeding; digital display wire feeder, the 15kg wire spool is applicable
