Multi-station welding rectifier VDM25-630

Welding rectifiers VDM25-630-2001 are intended for:

• To complete manual arc welding, cutting, surfacing posts with artificial electrodes on direct current;
• For automatic and mechanized welding under a layer of flux;
• For air-arc gouging and cutting.
• The rectifier is an unregulated power source and has a rigid volt-ampere characteristic.

The welding current is regulated using a ballast block of rheostats.

The rectifier consists of a powerful power transformer, a modern thyristor-diode rectifier module, with a classic air cooling system.

Advantages:

• simple design, high reliability and durability;
• convenient connection of welding posts;
• absence of quickly wearing electromagnetic contactors;
• Compared to similar rectifiers, it has the best technical and economic performance, modern design, and extended service life.
