Inverter welding machine DS 250.33

More than five thousand devices DC250.33 work at industrial enterprises, the construction of oil and gas pipelines, at the installation of production facilities, in emergency services. The structures of Gazprom and Transneft (Permtransgaz, Tyumentransgaz, Tattransgaz, Mostransgaz, Uraltransgaz, Volgoneftegazspetsstroy, Kubangazprom, etc.) rely on the equipment of NPP TEKHNOTRON due to its high technological properties, reliability, low weight and dimensions.

Description of the device ДС250.33

• Infinitely adjustable welding current in the range from 25 to 250 A. The accuracy of the current setting is up to 1A, controlled by a digital indicator.
• It has a digital display of welding parameters - Welding current, Degree of "forcing the arc", Tilt.
• It is made in the "safe version" - it has a reduced open circuit voltage of 12 V. (the device can be used for welding in especially dangerous conditions).
• It is equipped with a "hot start" system that provides easy excitation of the welding arc (short-term pulse of the welding current when the electrode is touched).
• Equipped with an anti-stick device that protects the electrode from sticking. (automatic shutdown of current at "sticking" of an electrode).
• It has the ability to adjust the "forcing" of the welding arc, which determines the behavior of the welding current at the time of reduction and further closure of the arc gap (Fig. 1). A decrease in "forcing" reduces metal spatter, and an increase in "forcing" reduces the likelihood of sticking of the electrode, increasing penetration and arc pressure.
