ionTig 200 Pulse PFC

ionTig 200 Pulse PFC Characteristics:

 DC Pulsed TIG and MMA, adopt IGBT and advanced PWM technology

 High performance MCU, Digital control, Digital display

 Preset all parameters with hold process

 HF/Lift TIG, current down slope and up slope, gas post-flow, Pulse Frequency

 Intelligent protection: over-voltage, under-voltage, over-current, over-heat

1. For MMA, polarity connection can be chosen according to different electrodes，please refer to

§3.5；

2. For DC TIG, DCEP is used normally (workpiece connected to positive polarity, while torch

connected to negative polarity). This connection has many characters, such as stable welding arc, low

tungsten pole loss, more welding current, narrow and deep weld;

3. DC Pulsed TIG has the following characters: 1) Pulse heating. Metal in Molten pool has short

time on high temperature status and freezes quickly, which can reduce the possibility to produce hot

crack of the materials with thermal sensitivity. 2) The workpiece gets little heat. Arc energy is focused. Be

suitable for thin sheet and super thin sheet welding. 3) Exactly control heat input and the size of the

molten pool. The depth of penetration is even. Be suitable for welding by one side and forming by two

sides and all position welding for pipe. 4) High frequency arc can make metal for microlite fabric,

eliminate blowhole and improve the mechanical performance of the joint. 5) High frequency arc is

suitable for high welding speed to improve the productivity.

TP-series welding machine 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, mold mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and

common manufacture.
