Apparatus DC 250.33 - industrial inverter source; current - up to 250A (duty cycle 100%) with microprocessor control for covered-electrode welding.
It is meant for use in factory (shop) and field conditions at supply by both mains and isolated generators.
Apparatus developed specifically for structural welding where stable high quality is required.
About five thousands of DC 250.33 units are applied at the industrial plants, gas and oil pipe-lines installation, industrial facilities mounting, emergency service. Gazprom and Transneft structures (Permtransgaz, Tumentransgaz, Tattransgaz, Severtruboprovodstroy, Mostransgaz, Severgazprom, Kavkaztransgaz, Uraltransgaz, Volgoneftegazspecstroy, Kubangazprom and others) choose NPP «TEHNOTRON» equipment owing to its high technological properties, durability, low weight and dimensions.
Sources are mounted on the repair cars КАМАZ, URAL, tractors DT-75, ТТ-4М и ТDТ-55А. In addition, damping devices are stocked for each DC 250.33.
Transportable welding 4-station welding unit with apparatuses DC 250 mounted on the all-wheel drive truck Welding carrier-unit.
