1. CHARACTERISTICS & APPLICATIONS 

This arc welder TIG-400P can invert the working frequency DC of 50Hz into the high frequency of 25KHZ, with built-in IGBT and the application of PWM technique, and reduces voltage, rectifies current and outputs a high DC power source and suitable for welding. Its functions include DC MMA, DC TIG welding and pulsed TIG welding. It can weld 0.6-14mm sheet, good result of welding seam. High efficient by H.F ignition . Possible to weld by 0.6mm down electrode .

Characteristics:

Adopt advanced inverter technology and IGBT switch element, high efficient and save power .

Adopt PWM pulse modulating technology, inverter frequency reach 25KHz .

Fast dynamic response, stable arc, excellence welding performance and good looking for welding seam.

The functions are rich and its welding process technology is excellent.

Arc igniting is stable and operation is easy with application of HF technique.

Protection is perfect: with over-current and over-heat protection, slow start up of current and anti-strike.

Applications:

a. It can be used for welding all kinds of carbon steel, iron, stainless steel, copper, titanium and other alloys.

b. It can be widely used in machinery industry, chemical industry, ship-building industry, vehicle industry, decoration industry, and power industries etc.
