Portable HF Pulse Inverter 500A DC TIG MMA 400A Welding Machine - China Suppliers & Factory with Stable Performance
Detailed Information
- Argon protection can isolate the adverse effects of oxygen, nitrogen, hydrogen, etc. in the air on the arc and molten pool, reduce the burning loss of alloy elements, and obtain dense, spatter-free, high-quality welded joints;
- The arc combustion of argon arc welding is stable, the heat is concentrated, the arc column temperature is high, the welding production efficiency is high, the heat-affected zone is narrow, and the stress, deformation and crack tendency of the welded parts are small;
- Argon arc welding is open arc welding, which is convenient for operation and observation;
- The electrode loss is small, the arc length is easy to maintain, and there is no flux or coating layer during welding, so it is easy to realize mechanization and automation;
- Argon arc welding can weld almost all metals, especially some refractory metals and easily oxidized metals, such as magnesium, titanium, molybdenum, zirconium, aluminum, etc. and their alloys;
- It is not limited by the position of the weldment, and can be welded in all positions.
