MACHINE DESCRIPTION
The welding machines are rectifiers adopting the most advanced inverter technology.
The development of inverter gas-shielded welding equipment benefits from the development of the inverter power supply
theory and components. The principle is to commutate the power frequency of 50Hz/60Hz into direct current first, and
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 welding power source can offer stronger, more concentrated and more stable arc. When stick and work piece get
short, its response will be quicker. It means that it is easier to design into welding machine with different dynamic
characteristics, and it even can be adjusted for specialty to make arc softer or harder.
MMA welding machine has the following characteristics: effective, power saving, compact, stable arc, good welding pool,
high no-load voltage, and good capacity of force compensation and multi-use. It can weld stainless steel, alloy steel,
carbon steel, copper and other color metal. It can apply to electrode of different specifications and materials, including
acidity, alkalescence, and fibre. It can apply in high altitude, the open air and inside and outside decoration. Compared
with the same products of home and abroad, it is compact in volume, light in weight, easy to install and operate.
Thanks for purchasing the product and hope for your precious advice. We will dedicate to produce the best products and
offer the best service.
WARNING
！
The machine is mainly used in industry. It will produce radio wave, so the worker should make fully
preparation for protection.
