What brand of argon arc welding machine is easy to use

Ling Rui, Dongsheng, Ruilong, Fiberhome, Ruicheng, Blu-ray, Welding King, etc. are all good, and the amount of argon arc welding machines is not large, and they are all good.

Different from TIG welding: one is that the welding wire is used as the electrode, which is continuously melted and filled into the molten pool, and then condensed to form a weld; The other is to use protective gas. With the application of MIG welding technology, shielding gas has developed from a single argon gas to a variety of mixed gases, such as argon-rich shielding gas with Ar 80%+CO220%.

Usually the former is called MIG and the latter is called MAG. From its operation mode, semi-automatic MIG welding and argon-rich gas shielded welding are the most widely used, followed by automatic MIG welding.

Non-melting argon arc welding;

Non-melting electrode argon arc welding is that the arc burns between the non-melting electrode (generally tungsten electrode) and the workpiece, and inert gas (generally argon gas) which does not react with the metal flows around the welding arc to form a protective gas cover, so that the tungsten tip, the arc, the molten pool and the metal at high temperature do not contact with air, which can prevent oxidation and absorb harmful gases. So as to form a dense welded joint with excellent mechanical properties.

The welding wire of MIG welding is fed through the wire wheel, and the conductive nozzle conducts electricity, so that an arc is generated between the base metal and the welding wire, and the welding wire and the base metal are melted, and the arc and the molten metal are welded under the protection of inert gas argon.
