Direct (Rectified) Current Welding Machine MSHV-8001

TU 16-739.251-80

This machine is designed for direct current roller spot pressure-tight welding of lightweight and titanium alloys, heat-resistant and stainless steels, low-carbon steels and non-ferrous alloys.

The machine performs longitudinal and transverse welds using the stepping rotation of the wheels. The current is rectified using a three-phase half-wave circuit employing silicon rectifying cells on the low-voltage side of the welding transformer.
