Welding Rectifier VД-309 УЗ for Manual Arc Welding - 300A Capacity

VD-309 U3 is a welding rectifier with power supply from 3-phase network 380V and rated current 300A. It is designed for manual arc welding, cutting and surfacing (MMA) low-carbon, low-alloy and corrosion-resistant steel piece covered electrodes with a diameter of 2 to 6 mm. Adjustment of welding current is smooth mechanical, by moving the magnetic shunt. The welding current is controlled by the scale on the shunt rod. Advantages of VD-309: <ul> <li>- the design of magnetic shunt, allows you to quickly change the value of the welding current;</li> <li>absence of moving windings increases reliability;</li> <li>high welding characteristics and reliability;</li> <li>thermal protection;</li> <li>welding with electrodes up to 4mm without limitation of continuous operation time;</li> <li>swivelling wheels for easy moving.</li> </ul>Main features of welding rectifier VD-309 Smooth adjustment of welding current Copper windings of the transformer Du Pont insulation No moving windings Forced cooling Range....
