MACHINE DESCRIPTION
The welding machine is a rectifier adopting the most advanced inverter technology.
The development of inverter welding equipment profits from the development of the inverter power
supply theory and components. The inverter welding power source utilizes high-power device IGBT to
transfer 50/60Hz frequency up to 15KHz, then reduce the voltage and commutate, and output
high-
power voltage via PWM technology. Because of the great reduce of the main transformer’s weight
and volume; the efficiency increases by 30%. The appearance of inverter welding equipment is
considered to be a revolution for welding industry.
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.
The 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, alkalescency, 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.
The welding machine is most suitable for welding tube, boiler, vacuum pressure vessel or the higher
quality for welding, which can gain perfect welding quality. In addition, this series machine have enough
no-load voltage and the ability of output, ideal for long cable welding.
Thanks for purchasing our product and hope for your precious advice. We will be dedicated 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.
