Pyongyang, May 12 (KCNA) — Scientists of the Laser Institute under the DPRK Academy of Sciences succeeded in manufacturing a plasma cutting and welding machine that does not require welding rods.
This machine was manufactured on the basis of the success made in developing interrupter-style plasma power equipment, taking the world trend of development and actual conditions of the country into consideration.
The body and weight of the machine is no more than half of the existing resistance-style or magnetic amplification-style welding machines each with the same power and its consumption of electricity is much smaller than any of them. The new machine is capable of cutting any metal materials 40 or 50 mm thick or 80 mm thick at maximum at the speed of 1m per minute..
It can weld even nonferrous metal materials such as aluminum and copper as well as steel. It can also weld materials about 20mm thick.
