Welding rectifiers “VSVU-400”, “VSVU-800”

Appointment


Welding rectifiers “VSVU-400”, “VSVU-800” are made for power supply of automatic and manual arc welding  plants of continuous and pulsed arc welding  of  heat-resistant, corrosion-resistant steels and titanium alloys by non-consumable electrode in argon medium. It is also possible carbon steels welding by covered electrodes.
