PRODUCT USE

WORKING PRINCIPLES

The operating principles of the welding machine are shown in the following figure. Single-phase with 220V AC
working frequency rectified to DC (350V); then converted to AC frequency (about 40KHz.) via the inverter device
(IGBT).
After reducing the voltage through the transformer (main transformer) and rectifying through the rectifier (fast
recovery diodes), inductance filtration is emitted.
The circuit adopts current feedback control technology to ensure stable current output when in MMA or TIG mode .
It also adopts voltage feedback control technology to ensure stable voltage output when in MIG mode.
The welding current parameter can be continuously and infinitely adjusted to meet the requirements of the welding
job.
