Company "Intreskol" produces a variety of power tools in the Russian Federation.In recent years, products of the brand is in great demand.This is largely due to the great capacity that has this company.
also "Interskol" is parallel developments in the field of improvement of work of power tools.As of 2013 20% of power tools in Russia have been released under this brand.In total, since the introduction of firm "Interskol" released about 24 million units.
Based Research and Production Company "Interskol" in 1991.Only on the territory of the Russian Federation is 17 plants, which produce products.Previously, the company was engaged in scientific developments at the Russian Institute of tools and machines.
in 1996 opened new laboratories engaged in research activities.There have also been launched with the support of the engineering departments of Science and Technology Center "Interskol."
In 1998, "Interskol" beginning to work with a big company for the productio
in 2002 opened a new shop in the town of Bykovo (Moscow region), which is engaged in manufacture of power tools.The next step is to increase the service shops from 160 to 200. Thus, repair welding inverters "Intreskol" has become easier, and the company is now able to provide greater assistance to maintain.

manufacturing inverters "Interskol" in Spain and Shanghai
In addition to Russia, separating "Interskol" exist in the city of Ripoll (Spain), as well as in the city Dzinhua (Shanghai).Basically they are doing is producing welding inverters.In addition, they have to provide services in the field of processing of concrete and wood.The company "Interskol" has permission to carry out the installation and anchoring works.
What welding inverters?
Welding inverters - a relatively recent invention, which has already established itself as a trusted associates.Welders have been able to appreciate all their advantages and disadvantages.Previously had to deal with simple welding machines.Their transportation was very difficult, given the weight of the unit.Inventions welding inverters for a long time pushed aside and old transformers and rectifiers.The secret lies in their principle of operation.
operating principle of the welding inverter
all starts with the receipt of the AC, which has a frequency of 50 Hz.Then it undergoes certain changes with the help of special filters, which are in the welding inverter.As a result of these processes is already available at the output of a constant current.Later in the course of entering the inverter directly.Its task is to convert the DC power by transistors.At the same time there is a significant reduction in the frequency and the current remains consistently high.Thus the problem with the welding arc has been solved by using frequency manipulation.
Pros welding inverters
main advantage of inverter welding is, of course, their light weight.Additionally, it became possible to use the DC electrodes.To a large extent this was useful when working with non-ferrous metals.You can also see a large range of current that can be adjusted.This allowed to engage in TIG welding, which feature is the use of non-consumable electrode.
Additionally, many models have an opportunity to make a hot start.The principle of this function is to quickly supply the maximum current to the electrode.This avoids when sticks to the surface of the wire during welding.
Cons inverter welding
cost of these devices is very different from conventional transformers.In addition, repair welding inverters - a very costly exercise.Plus, they are very susceptible to dust.Therefore inverters require periodic inspection.To do so, each time to open the lid and remove all dirt.Also, there are significant restrictions on the temperature conditions in which welding inverter can be used.This largely depends on the details of which are installed therein.Whatever it was, it is strictly not recommended to include already at -15 degrees.
addition of the disadvantages of welding inverters can be identified relatively small welding cables.This fact creates certain difficulties during operation, but is not critical.
Welding inverter: Which is better?
To date, the most popular model "ISA-200 / 9.4", "ISA-250 / 10.6", "ISA-160 / 7.1" and "ISA 180 / 8.2".In order to make the right choice, a more detailed examination of their characteristics are summarized below.
