These compact inverter rectifiers are intended for tungsten-arc argon (TIG) welding and also for manual metal-arc (MMA) welding both inside premises and on open air. The devices of a series LTN can work on a pulsed current, providing high quality at welding small thickness and also allows to enter into storage four sets of welding parameters. Presence of function " hot start " and opportunity of change of dynamics of the rectifier (" force of arc ") lead MMA welding (manual metal-arc welding) on a completely new level.

   The compact welding half-automatic devices ESAB Original 150/180/240 give the user a maximum of advantages carbon-steel metal-arc active-gas (MAG) welding. By these devices it is possible also to weld aluminium and stainless steels. They can be the ideal assistants in garage and on a summer residence, on a farm and in small workshop at repair work.

 The devices LAX with step-adjustment of a voltage are intended for welding in industrial conditions. They concern to a series A10, which gives wide opportunities on integration by different feeder wire, torches and accessories to maintenance of the requirements of the concrete customer LAX can be delivered with the built-in block of water cooling or without it. In the completely closed feeder wire MEK2 and MEK4 can be established 5 -, 15- and 18- kilograms coils.

The power supplies LAW 410 and 510 are intended for metal-arc active-gas (MAG) in heavy conditions both in premises and on open air. They have the fine characteristics at welding both in pure CO₂ and in mixes of gases in a wide range of a welding current and allow to use both solid and cored wire. At use of the feeder wire IVIEK 4SP with LAW 410 it is possible to weld aluminium and stainless steel of small thickness in a pulsed current. Radius of a working zone can achieve 65 meters at use of the in-between feed mechanism and longer of cables.

The rectifiers LHF 400/630/800 are designed specially to answer the highest requirements on reliability in heavy conditions of work. The hull has a aluminium-zinc covering ensuring high corrosion-resistance, and all collecting of transformers and switches got out proceeding from their high reliability. The dynamic characteristics of a source, range of a welding current, "anti-stick function" of electrode and large capacity do LHF by the Irreplaceable tool for the enterprises, for which the first-class equipment is necessary. LHF 400 is recommended VNIIST (All-Union Research and Development Standards institute) for welding gas-oil-pipes.

The welding transformers of a type MMA are intended for manual-arc covered-electrode welding on an alternating current mild and low-alloy steels. The adjustment of a welding current is provided with mechanical manual moving of the magnetic shunt of horizontal performance. They are convenient at moving in assembly conditions. A reliable design do them durable and trouble-free in work.

The rectifiers of a welding type are intended for a complete set of semi-automatic devices of arc welding, for manual-arc-electrode welding on a constant current carbon and alloyed steels for industrial and repair-building-up works. In the rectifier the classical technical decisions are widely used.   Simplicity and reliability of a design, improvement of welding units do work with rectifiers pleasant both for beginning operators and for the professionals.

Of   Russian firms and Swedish firm ESAB

Today ESAB offers wide scale of welding technologies both materials for building-up and repair of various details. The electrodes OK are recommended a number of branch-wise institutes for application in shipbuilding, at construction of pipelines, in a chemical and petroleum industry. Their quality is confirmed by long-term application at welding oil- and gas-pipelines in severe climatic conditions of Siberia and hot climate of southern areas of the countries of SNG.
