The universal invertor-rectifier welding unit is designed for automatic and semi-automatic gas-shielded welding and submerged-arc welding with all the types stick electrodes. The voltage and welding current slide control is made using the electronic control unit.
The invertor-rectifier welding unit has the excellent welding properties: the arc stable ignition, small scattering. It can be used as a multipost power supply being furnished with choppers or ballast resistor.
