MACHINE DESCRIPTION 

MIG350  CO

gas  shielded  welding  machines  of  our  company  are  inverter  welding  machines  manufactured  by  our 

company applying most advanced inversion technology in the world.   

The  development  of  welding  equipment  benefits  from  the  appearance  of  the  inverter  power  supply  theory  and 

components.  The  principle is to commutate the  power  frequency  of 50Hz/60Hz  into direct  current, and then  utilize  the 

high-power device IGBT to invert it into high frequency (15K/16K), then reduce the voltage and commutate, and output 

high-power D.C power supply via Pulse Width Modulation (PWM). Since the switch power inversion technology is adopted, 

the weight and volume of the welding machine is brought down greatly with a conversion efficiency increase of more than 

30%. Characteristic: stable wire feed rate, little splatter, portable, energy-saving, low electromagnetic noise.   

The  CO

2

  gas  shielded  welding  machine  of  our  company  is  equipped  with  unique  electronic  reactor  circuit,  precisely 

controlling  the  short-circuiting  transfer  and  mixed  transfer  of  welding,  producing  excellent  welding  characteristic. 

Compared with silicon controlled welding machine and welder with taps, our products have the following merits: stable 

wire feed rate, portable, energy-saving, electromagnetic noise free. Besides, our products have merits such as electric 

network fluctuation self-compensation  function,  little  splatter,  good  arc  starting,  deep  welding  pool,  high  duty  cycle  etc. 

This  equipment  can  be  applicable  in  large-scale  plants  such  as  shipyards,  steel  structure  plants  etc.  featuring  high 

efficiency and energy-saving.   

The CO

2

 gas shielded welding machine of our company has function of ending arc On/Off. Arc starting current and ending 

arc current can be adjusted separately, being very applicable for automatic welding. This machine is most suitable for the 

welding of mild steel, alloy steel and stainless steel.   

Thank  your  for  choosing  our  products.  Please  feel  free  to  propose  your  valuable  suggestions;  we  will  make  efforts  to 

perfect our products and service.

   

 

WARNING

 

The machine is mainly used in industry. It will produce radio wave, so the worker should make   

fully preparation for protection.
