Steel welding wire https://ukrstarline.ua/ru/nerzhaveyushij-metalloprokat/nerzhaveyushaya-provoloka is used to process refractory metals. The operation of the wire is as follows: the electrode metal thread is fed at a constant or variable speed instead of welding. At the same time, gas is directed to this point, which protects metals heated to a high temperature from the negative impact of the environment. Carbon dioxide or argon is supplied from a cylinder using a gas reducer.
