The welding rectifier is designed for semi-automatic gas-shielded arc welding. The increased number of steps of welding voltage switching allows covering a wide range of welding currents with low increment without usage of complex electronic devices, which provides for excellent welding properties, minimum spattering, saving of welding materials.
The rectifier is easy to operate and reliable in operation.
The rectifier has a diode power unit with a current safety factor of K = 1.25.
