60 years of PATON


Formation of the Experimental Plant, on the initiative of B.Ye. Paton, as one of the components of the Institute of Electric Welding, which included: the Institute, the Research Design Bureau and the Research Plant.

During these years, the plant has widely developed new technological areas, which allowed to produce not only single units developed by the institute and DKB, as well as some samples in the form of small-scale production. One of them is a small transformer STSH-250, designed for installation and repair work.



In 1963, the plant manufactured and began to supply the Chelyabinsk Pipe Rolling Plant with special A 850 and A 943 devices for welding large-diameter pipes used for the Bukhara-Ural and Druzhba gas pipelines.


In 1964, the plant delivered A 899 machines designed for welding tractor spars to the Volgograd Tractor Plant. Welding equipment manufactured by the Research Plant has been successfully demonstrated during these years at international exhibitions and fairs in Brussels, New York, Marseille, Leipzig and the USSR Exhibition of Economic Achievements.


On October 16, 1969, the crew of the Soyuz-6 spacecraft, consisting of cosmonauts V. Kubasov and G. Shonin, for the first time in orbit with the help of a unique Vulcan installation manufactured at the Experimental Plant, performed electron beam, plasma and fusible electrode welding.


In 1970-1972, new production areas were developed, which allowed to significantly expand the range of welding equipment.


In 1972, the plant began manufacturing special equipment for agriculture.


In 1973, the start of production of special multi-station rectifiers VMG 5000 for the shipbuilding industry, as well as devices for electroslag, contact and microplasma welding, which were not produced by other plants in the USSR.


In 1975, the plant produced special equipment “Araks” for the Soviet-French scientific experiment in outer space between the island of Kerguelen – France and the village of Sogra in the north of the USSR using the rocket “Eridan”.

Three products of the plant: VMG 5000 rectifier, A1114M semiautomatic device and STSH-250 transformer are awarded the state Quality Mark.



In 1976-1978 the plant successfully manufactured and delivered to the plant ZIL technological line U-851 for welding frames, Khartsyzsk Pipe Plant installation U 901 for collecting and welding joints of multilayer pipes of large diameter, Kharkiv Tractor Plant installation UD 133 for welding units of serial tractor T – 150.


In 1975-1980, the plant supplied more than 50 sets of welding equipment to Japan, Sweden, Germany and the United States. Auto giants became regular consumers: VAZ, ZIL and KAMAZ.


In 1979, the plant manufactured a unique installation “Evaporator” for thermal evaporation of metals and thin film coatings on board the space complex “Salyut-6” in weightlessness and seaworthy vacuum on a number of samples made of structural materials.

This important experiment once again confirmed the advantage of the research and production complex of the EEZ. EA Paton, which unites scientists, designers and manufacturers.


In 1980, a whole complex of special welding equipment for mechanization of welding works, control of operations in the production of multilayer pipes was manufactured and delivered to the Viksun Pipe Plant.

In 1985, the Intersectoral Scientific and Technical Complex (ISTC) was established, which includes the Research Plant.



The most difficult years in the history of the Experimental Plant. The collapse of the Union significantly affected the industry of all union republics, including Ukraine. The need for unique installations for different welding methods has significantly decreased, the plant has sharply reduced production.

We had to abandon a large branch of the plant. All equipment was transported to the main plant. Despite this, the plant continued to produce new developments of the EEZ and DKB, but already under the real orders of consumers in the CIS countries.

In the late 90’s there is a revival of industrial production and construction. The need for power supplies for various welding methods is growing sharply.

The decision was made to master the production of the most popular transformers, rectifiers and semiautomatic devices. The plant independently developed and mastered small-scale production of transformers of the STSh type for currents of 250, 315 and 400 amperes, rectifiers of the VD type for currents of 250,315 and 400 amperes and modernized semiautomatic devices for currents of 180,250 and 315 amperes.


In the early 2000s, the EEZ completed the development of the USGD arc stabilization device, which significantly improves the AC welding process and allows the welding of small-thickness aluminum alloys using a transformer as a power source.

Employees of the plant finalized serial transformers of STSh and installed in them stabilizers of burning of an arc of SRS. In rectifiers VD provided the possibility of installing two small blocks that improve the excitation of the arc and eliminate the adhesion of the electrode when welding at low currents of the root seam not only pipes but also other metal structures.

Significantly modernized semiautomatic devices and introduced production in two versions: the power supply in the same case with the feed mechanism and the rectifier and the feed unit are made separately.


So far, the plant, taking into account the appearance on the international markets of inverter power supplies, mainly for manual arc welding, has created a group of employees and instructed them to develop and start production of inverter equipment.


In 2008, the plant already produced small batches of inverters for manual arc welding for currents of 120, 160 and 200 amps of three modifications.


Until 2013, the plant produced special orders for equipment for arc welding, surfacing and electroslag remelting.

2013. Not only is the output of conventional power supplies increasing, but also in large volumes inverter sources are not only for manual arc welding.

According to special orders, the production of powerful power supplies for electroslag welding and remelting at currents of 3000, 6000 and 10000 amperes, as well as three types of tractors for submerged arc welding and flux-cored wire at currents up to 1000 amperes was resumed. As power supplies for tractors, the plant develops and implements universal VSU rectifiers for currents of 630 and 1200 amperes.

The country is resuming work on plants for the manufacture of metal structures, construction companies which are widely used arc welding.

Therefore, in 2013 the plant mastered the production of multi-station rectifiers for currents of 630 and 1200 amps, and for installation and repair work, as well as significantly increased the production of inverter equipment.


In 2014, the plant completed the production of unique 4 units for welding turbine rotors for the Kharkiv association “Turboatom”.

The units were developed by the Institute’s Design Bureau and, together with the plant, were successfully implemented at Turboatom.


Since the beginning of 2015, the Plant resumes work on developments in the field of welding equipment.

Thus, since May 2015, serial production of ballast rheostats RBP-304 for regulating the welding current during multi-station welding with Paton rectifiers has been introduced. And since June 2015, universal welding rectifiers VDU-6303P and VDU-1202P are launched, designed for automatic and semi-automatic welding in protective gases and under flux, as well as manual arc welding with artificial electrodes of all types. Smooth regulation of welding voltage and current is carried out by means of the electronic control unit. When equipped with ballast rheostats, these rectifiers can be used as multi-station power supplies.

Also in early May 2015, the Plant completed a contract, together with the Institute’s State Design Bureau, for Ukrspetsexport to develop and produce a batch of welding equipment for tropical climates with improved characteristics and increased reliability.

Welding rectifiers model VS-650 SR complete with BP-608 units, as well as inverter rectifiers VDI-200R were tested and sent for use at one of the shipyards in Southeast Asia (Union of Myanmar).

In June 2015, the first batch of new welding inverters “PATON” series “ECO” is released. The “ECO” series is environmental friendliness and economy. The key advantages of these devices are small weight and size parameters and the ability to work with weak (sagged) networks, which is important when choosing a welding machine for household purposes. Despite the principle of complex economy, which was used in the development of the series “ECO”, these devices are equipped only with high-quality electronic components and mechanical modules. The “ECO” series is designed for manual arc welding with an electrode connected to the household network (220V) and is represented by three models for welding currents 160A, 200A and 250A, with a load duration of 40%.

In October 2015, the plant occupies a leading position in the TOP 5 sales of the Epicenter K network. Since April 2015, welding machines have been produced monthly, exclusively presented in the largest retail chain of hypermarkets in Ukraine Epicenter K under the EVO brand. The plant’s products successfully compete with other foreign manufacturers, displacing even Chinese manufacturers of welding equipment in terms of “price-quality”. The main reasons for the stable interest of customers in the equipment of the Plant from TM EVO are:

  • domestic production (made in Ukraine),
  • adaptation of work of devices at the lowered voltage in a network (from 170 V),
  • warranty period of service is 2 years,
  • competitive price.

At the beginning of November 2015, the plant supplied welding equipment for the re-equipment of the car-building plant of the CKD Kutna Hora as Group of Companies (Czech Republic) – SCB Foundry, which is one of the largest producers of quality cast products in Europe.
