TIG Welder Wave Frequency Control Arc Inverter IGBT Digital Welding Machine


TIG Welder Wave Frequency Control Arc Inverter IGBT Digital Welding Machine

TIG welding machine adopts the latest pulse width modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module, which can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer. Thus, it is characterized with portable, small size, light weight, low consumption and etc.

The parameters of TIG on the front panel all can be adjusted continuously and steplessly, such as start current, crater arc current, welding current, base current, duty ratio, upslope time, downslope time, pre-gas, post-gas, pulse frequency, AC frequency, balance, hot start, arc force and arc length etc. When welding, it takes high frequency and high voltage for arc igniting to ensure the success ratio of igniting arc.

TIG  Pro -series welding machine is suitable for all positions welding for various plates made of stainless steel, carbon steel, alloyed steel, titanium, aluminium, magnesium, cuprum, etc, which is also applied to pipe installment, mould mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and common manufacture.


Product functions:
• DC Pulse TIG
• AC Pulse TIG


DC MMA, polarity connection can be chosen according to different electrodes.
AC MMA, magnetic flow caused by invariable DC polarity can be avoided;
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;
AC TIG (rectangle wave), arc is more stable than Sine AC TIG. At the same time, you can not only obtain the max penetration and the min tungsten pole loss, but also obtain better clearance effect.

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.



• Advanced IGBT inverter technology
• Industry leading control system -MCU control system, responds immediately to any changes
• Inverting frequency of 33~43 kHz greatly reduces the size and weight of the welder.
• Great reduction in magnetic and resistance loss enhances the welding efficiency and energy saving effect.
• Working frequency is beyond the audio range, which almost eliminates noise pollution.
• TIG/DC operation, If the tungesten electrode touches the workpiece when welding, the current will drop to short-circuit current to protect tungsten
• High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc, the reverse polarity ignition ensures good ignition behavior in TIG-AC welding
• Pedal control the welding current
• Double purposes : AC inverter TIG/MMA and DC inverter TIG/MMA, Excellent performance on Al-alloy,carbon steel,stainless steel,titanium
• Intelligent protection: over-voltage, over-current, over-heat, when the problems listed before occurred, the alarm lamp on the front panel will be on and the output current will be cut off. It can self-protect and prolong the using life
•Bionic and Ergonomic industrial design.
• Water-resistant, antistatic and anticorrosion design.
• Avoid AC arc-break with special means, even if arc-break occurs the HF will keep the arc stable.
