Rectifier welding VDM25-2001

The rectifier is the unregulated power supply and has the tough volt - ampere characteristic. Regulation of welding current is made by means of the block of ballast rheostats of BBR 1200 or RB 302.

The rectifier consists of the powerful power transformer (which coils are executed from the copper tire), the modern vypryamitelny thyristor and diode module with classical system of air compulsory cooling.
In comparison with similar rectifiers, the source of production "AMITY" has the following advantages:
- simple design, high reliability and durability of work;
- convenient connection of welding posts;
- absence of the fast - wearing - out electromagnetic contactors
