3. The REHM RP 462 welding device

        This type of device is a welding source that is used for operations in a protective environment using the MIG/MAG process with a constant voltage characteristic where the welding voltage is regulated via a tap switch.

        It uses welding wires with different diameters and materials. Protective gas is used in mixture of 82% Ar and 18% CO₂ , steel with 100% CO₂ protection_,  stainless steel with 98% Ar protection and 2 % CO₂, or clean Argon ( for aluminium).

        Technical specifications:
