The unit welding with universal characteristics of ADDU-4001PR is intended for use as the independent power supply by a direct current of one post at:
to manual arc welding, cutting and naplavka of metals (MMA) the piece covered electrodes;
to the mechanized welding by the melting electrode in the environment of protective inert or active gases (MIG/MAG) of gases, or with use of a self-protective powder wire at a unit complete set the corresponding semiautomatic device;
to plasma cutting of metals up to 30 mm thick (it is equipped with compressor installation, system of preparation of compressed air, the socket for connection of the plasmatron).

The unit incorporates the auxiliary generator of alternating current of 230B, 50 Hz for power supply of the electric tool, lighting and other consumers.

The ADDU-4001PR unit is the latest development and significantly differs from all known units of the ADD series in the welding properties. Use of the reliable power tiristor operated by the microcontroller provides formation of external characteristics for different types of welding.

At manual arc welding by the covered electrode the ADDU-4001PR unit provides:
the combined external volt-ampere characteristic consisting of four sites (pologopadayushchy, krutopadayushchy, vertikalnopadayushchy and a site of short circuit);
smooth regulation of welding current in the range from 40 to 400A without intermediate switchings;
remote regulation of welding current at distance to 20 m from the unit;
choice and installation of an inclination of a working site of the external characteristic. It allows to receive both high stability of current, and a possibility of its fast change at a manipulation arch length, for example for deduction of a bathtub when welding in vertical and ceiling provisions;
the "hot start" mode - adjustable increase in current at ignition of an arch that provides almost faultless ignition, and also high quality of an initial site of a seam;
mode of speeding up of current of short circuit. Depending on type of a covering of an electrode and the spatial provision of a welded seam it is provided on the one hand, small spraying, and with another - vigorous transfer of a drop without sticking of an electrode to a bathtub that it is especially important when welding vertical and ceiling seams;
function of protection against sticking which limits current of long short circuit thanks to what durability of sticking of an electrode to a detail decreases, peeling of a covering of an electrode is prevented and repeated ignition is facilitated;
restriction of tension of idling with a safe size of 12B
