Advantages over analogues: In the AC transformers, due to their inherent reliability, durability, low cost, are the most common source of welding power. Their main drawback - the watchdog interrupt arcing caused by periodic welding voltage transitions through zero values ??by changing the polarity of the electrode and the product. This disadvantage can be overcome by installing a transformer in the stabilization unit arc (SRS), which enables the expense of stabilizing pulses (up to 600 V, 100 Hz) to support the burning of the arc at the moment when the main voltage zero crossing, weld on AC electrodes of any type and TIG welding of all metals (aluminum, copper, stainless steel, etc.) in those cases where the initial ignition of the arc allowed by contact, while replacing expensive installations such UdSU.

The development stage readiness: Introduced in production

Description of the development:
()
Welding rectifiers 310 HP used for manual arc welding, cutting and surfacing of steel structures and components, including the most severe operating conditions: metallurgical, mining, chemical production, in the field, at work on the installation and repair of oil and gas pipelines, etc. Sources are not sensitive to temperature fluctuations in the network to high dust and moisture. Rectifiers provide quality formation of joints in welding of all types, including cellulosic, low spatter, easy arousal and increased elasticity of the arc, smooth crater filling. Universal type setting HP-255 and HP 400 (401) can be successfully used as a power source (AC / DC) for welding with coated electrodes and a low-cost installation TYPE UdSU AC / DC. When welding in DC mode, the special design of the throttle provides exceptions mezhtokovyh pauses during welding. Also, due to the special unit, provides high open-circuit voltage in pulse mode (up to 75V), which makes it possible to significantly improve the conditions for the start of welding ("hot" start). In general, the DC mode is provided at the level of the quality of welding rectifier type known VD 306 (welding with coated electrodes). When welding in AC systems operate in the mode of the welding transformer of TSS-250 and TSS 400 (401) with SRS.
