Description of equipment

Compact 400-I is a 3-phase source of constant voltage, output 300A/DZ 100%, with built-in 2-roll wire feeder.
Design of this source combines excellent features of welding source CV 400-I and wire feeder LN 742 with full integration of all functions and parameters. Microprocessor control of output voltage provides permanently excellent welding output both, with solid and cored wire.

Perfectly tested robust electronic circuits ensure very long life. Built-in diagnostics serves for easy search of faults.

This source is provided with feedback ensuring exact control of wire feed speed, independent on wire feed resistence and fluctuations of feed voltage.

Robust dynamic brake does not require any maintenance, quickly stops motor, so that overtravel is minimal.

Easy replacement of guide rolls enables to use a wide range of wire diameters, 0,6 – 1,6 mm for solid wires, 1,2 – 2,4 mm for cored wires and 0,9 – 1,6 mm for aluminium wires.

Transformer assembly, reactance coil and rectifier is covered with special sealing and insulating material, protecting circuits against moisture and corrosive influences of atmosphere.

Easily removable side covers and modular design enable quick maintenance and attendance.
Front panel contains switches, control lights and connectors for easy control and attendance. These sources are provided with undercarriage with platform for bottle with a shielding gas and for easy installation of water cooler.
