500A Portable HF Pulse Inverter TIG MMA Welding Machine - High Duty Cycle from China Suppliers & Factory
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.

Frequently Asked Questions
What are the primary benefits of Argon protection in welding?
Argon protection isolates the adverse effects of oxygen, nitrogen, and hydrogen in the air from the arc and molten pool. This reduces the burning loss of alloy elements, resulting in dense, spatter-free, and high-quality welded joints.
Which metals can be welded using these machines?
Argon arc welding can weld almost all metals. It is particularly effective for refractory metals and easily oxidized metals, including magnesium, titanium, molybdenum, zirconium, aluminum, and their alloys.
What is the difference between WSM-400 and WSM-500 models?
The WSM-400 has a current range of 20-400A and weighs 27.5Kg, whereas the WSM-500 has a current range of 20-500A and weighs 38.5Kg. The WSM-500 also has a larger cabinet structure and higher rated input capacity to handle heavier duty cycles.
What are the electrical requirements for installation?
The machines require a 380V AC±10% (50/60Hz) input voltage, an input cable size of ≥6 mm², an output cable size of 50mm² (with a welding gun length ≤10m), and a dedicated 63A power switch.
What conditions are optimal for operating the welding machine safely?
The machine operates best in ambient temperatures between -10℃ and +40℃. It requires good ventilation conditions and should be kept away from excessive dust, moisture, and direct water exposure.
