The Intreskol company is engaged in the production of various power tools in the territory of the Russian Federation. Recently, the products of this brand are in great demand. This is largely due to the large capacities that this company has.
Also, Interskol is simultaneously developing in the field of improving the operation of power tools. As of 2013, 20% of power tools in Russia were produced under this brand. In total, since its inception, Interskol has produced approximately 24 million units.
Opening Interskol
The scientific and production company Interskol was founded in 1991. Only on the territory of the Russian Federation there are 17 workshops that are engaged in the production of products. Previously, the company was engaged in scientific development at the All-Russian Institute of Tools and Machines.
In 1996, new laboratories were opened that were engaged in research activities. Engineering departments were also launched with the support of the Interskol Scientific and Technical Center.
Company partners
In 1998, Interskol began to collaborate with a large arms manufacturing company located in Izhevsk. This partnership allowed us to begin production of rotary hammers, as well as circular saws. Since 2000 , Interskol begins to increase momentum, and in one year the company began to produce more than 400 units. Additionally, a conveyor for the production of planers and jigsaws was launched.
In 2002, a new workshop was opened in Bykovo (Moscow region), which is engaged in the production of power tools. The next step is to increase the service shops from 160 to 200. Thus, the repair of Intreskol welding inverters has become easier, and the company is now able to provide great assistance in servicing.
It should also be noted that this company never stopped and continued to produce new types of goods every year. Recently, the production of miter saws, polishing machines, and milling machines was launched.
Interskol inverters production in Spain and Shanghai
In addition to Russia, Interskol branches exist in the city of Ripol (Spain), as well as in the city of Jinhua (Shanghai). They are mainly engaged in the production of welding inverters. In addition, they provide services in the field of concrete and wood processing. The Interskol company also has permission to carry out installation and anchor work.
What are welding inverters?
Welding inverters are relatively recent inventions that have already established themselves as reliable assistants. Welders have already been able to appreciate all their advantages and disadvantages. Previously, I had to deal with simple welding machines. Their transportation was very difficult, given the weight of the units. The inventions of welding inverters for a long time pushed aside both old transformers and rectifiers. The whole secret lies in their principle of action.
The principle of operation of welding inverters
It all starts with the arrival of alternating current, which has a frequency of 50 Hz. Further, it undergoes certain changes with the help of special filters that are located in the welding inverter. As a result of these processes, direct current is already output. Next, the inverter enters directly. Its task is to convert direct current using transistors. In this case, a significant reduction in frequency is observed, and the current remains invariably high. So the problem with the welding arc was solved using frequency manipulations.
Advantages of welding inverters
The main advantage of all welding inverters is, of course, their low weight. Additionally, it became possible to use DC electrodes. To a large extent, this has become useful when working with non-ferrous metals. You can also notice a large current range that can be adjusted. This made it possible to engage in argon-arc welding, a feature of which is the use of non-consumable electrodes.
Additionally, many models have the opportunity to make a hot start. The principle of this function is to quickly supply maximum current to the electrode. This avoids cases where the wire sticks to the surface during welding.
Cons inverters for welding
The cost of these devices is very different from conventional transformers. In addition, repair of welding inverters is a very expensive undertaking. Plus, they are very susceptible to dust. In this regard, inverters need periodic inspections. To do this, each time you open the lid and remove all dirt. There are also significant restrictions on the temperature regime in which the welding inverter can be used. This largely depends on the details that are installed in it. Be that as it may, it is categorically not recommended to be included already at -15 degrees.
In addition, relatively small welding cables can be distinguished from the disadvantages of welding inverters. This fact creates certain difficulties during work, but is not critical.
