semiautomatic and automatic welding
VDG-401 is designed to be used with PDG-401 arc-welding semiautomatic
units. As a part of the semiautomatic unit, the rectifier is used for direct current,
semiautomatic welding of steel work pieces with consumable electrodes in protective
gas environments. Provided the ballast resistor is available, DC welding with
a coated electrode is possible. Constant
external characteristic Stepless control of the welding current
36 V socket is available for powering the gas heater Quick-release safe
current connectors Insulation class N, according to GOST 8865-70
