Metal Welding

Argon can effectively isolate air, is insoluble in metal and does not react with metal. During welding,

Tungsten electrode arc is stable, and dozens of it can still burn stably under a small welding current (less than 10a),

The heat source and filler wire can be controlled separately, so the heat input is easy to adjust, and welding at various positions can be carried out.

There is no coating layer on the surface of the welding wire, and the welding current can be increased.
