Semi-automatic machine having a wide control range of welding parameters is designed for all-position gas-shielded arc welding at constant current in the protective gas environment with a consumable electrode with solid or flux-cored wire of low-alloyed and alloyed steels, as well as corrosion-resistant (stainless) steels in argon gas atmosphere. The semi-automatic machine is equipped with welding rectifiers КИГ-401 and КИУ-501.
The wire feed mechanism is mounted in a compact open-type casing together with a wire reel magazine, controls and a gas cutoff. In the semi-automatic machine, a two-roller wire feed gearing mechanism with the power of electric motor of the wire feed reduction gear of 100W is used, which ensures reliable uniform feeding of both solid and flux-cored welding wires.
Lightweight feed mechanism for operation in confined spaces.
Stepwise regulation of welding voltage by the power source КИГ-401 (switch).
Smooth regulation of welding voltage by the power source КИУ-501 (resistor).
