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:
- the design of magnetic shunt, allows you to quickly change the value of the welding current;
- absence of moving windings increases reliability;
- high welding characteristics and reliability;
- thermal protection;
- welding with electrodes up to 4mm without limitation of continuous operation time;
- swivelling wheels for easy moving.
