Working Mechanism of the 220V MIG Welder
The 220V MIG welder operates on the principle of arc discharge. When the welder is powered on, a stable arc is formed between the welding gun and the workpiece, with a voltage of 220V. During this process, the wire electrode is continuously fed into the arc area, where it melts and fuses with the base material to form a solid weld. To prevent oxidation of the molten pool, the 220V MIG welder releases an inert gas, typically argon or a mixture of carbon dioxide, which covers the welding area and effectively isolates it from atmospheric oxygen, ensuring high-quality welding.

Range of Materials Suitable for 220V MIG Welders
The 220V MIG welder's versatility and flexibility make it capable of handling various metal materials. For common carbon steel, the 220V MIG welder can achieve high-quality welding results effortlessly. When dealing with specialized alloy materials like stainless steel, the 220V MIG welder performs exceptionally well, requiring only appropriate adjustments to welding parameters to achieve satisfactory outcomes. Additionally, for lightweight and easily oxidized aluminum materials, the 220V MIG welder is an ideal choice. By precisely controlling the welding current and wire feed speed, even challenging aluminum materials can be successfully welded.
