molten pool. The depth of penetration is even. Is  suitable for welding  all positions  for pipe. 4) High 

frequency arc can eliminate blowholes and improve the mechanical performance of the joint. 5) High 

frequency arc is suitable for high welding speed to improve productivity. 

   ArcoTig HF200P is suitable for all positions welding for various plates made of stainless steel, carbon 

steel, alloyed steel, titanium, magnesium, cuprum, etc, which is also applied to pipe installment, mould 

mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and common manufacture. 

MMA——Manual Metal Arc welding 

PWM——Pulse-Width Modulation 

IGBT——Insulation Gate Bipolar Transistor 

TIG——Tungsten Insert Gas welding 

2.2 Module Explanation 

HF= High Frequency 

200- Amperage

P- Pulse modulation

2.3 Working Principle 

   

The working principle of ArcoTig HF200P  is shown as the following figure. Single  phase  work 

frequency AC  110V/220V  (50 Hz) is rectified into DC  (about  380V), then is converted to medium 

frequency AC (about 40KHz) by inverter device (IGBT), after reducing voltage by medium transformer 

(the main transformer) and rectifying by medium frequency rectifier (fast recovery diode) and  is 

outputted by inductance filtering. The circuit adopts current feedback control technology to insure 

current output stably. Meanwhile, the welding current parameter can be adjusted continuously and 

steplessly to meet with the requirements of welding craft.
