MACHINE DESCRIPTION
MIG200G CO
2
gas shielded welding machines of our company are inverter welding machines manufactured by our
company applying most advanced inversion technology in the world.
Their 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 (15 KHz/16KHz), then perform voltage-drop 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.
