TIG argon-arc welding machines HELVI COMPACT EVO 300 AC/DC, etc.

TIG inverter sources. Often, in the practice of a private welder, it becomes necessary to carefully connect very thin, often aluminum parts (for example, in car repairs). Only the technology of argon-arc welding TIG will help here. This is a type of manual arc welding. But, unlike MMA, it is carried out by a non-melting tungsten electrode in a protective gas environment (most often argon). The weld is formed by melting the edges of the connected parts. Sometimes, to strengthen the joint, a filler rod or wire made of the same metal as the workpieces being welded is used. The main advantages of TIG welding are: there are no splashes of melting metal, local heating avoids deformation of the workpieces, the electrode does not melt, therefore it is easier to control the welding bath and arc length, the gas medium protects the welding zone from oxidation and slag formation.
