Our 120GDps series IGBT inverter digital MMA welding machine is designed with a digital control panel, optimizing control accuracy. With a self-designed elliptical structure that is beautiful and innovative in appearance, the IGBT welding machine is small and easy to carry around. It is widely applied in household DIY welding projects to join carbon steel, regular low alloy steel and stainless steel.

• For our 120GDps series IGBT inverter MMA welding machine, contact-type arc ignition method is applied. Using this method, an arc will be easily established as soon as the tungsten electrode is brought into direct contact with the workpiece to form short circuit.
• The built-in thrust regulation system will prevent welding current from changing as the arc length varies, ensuring stable welding current and it will also eliminate arc extinction during the welding process. As a result, the closer the electrode is to the workpiece, the larger the welding current is and the smaller the welding spatter is.
• In case of excessively high voltage or current, the MMA welding machine will automatically stop running, thereby ensuring safety during the welding process.
• VRD (voltage reduction device) featured with electric shock protection will contribute to low open circuit voltage, making the welding equipment more applicable for household welding process.
