Our MIG140/155/180G series IGBT inverter MIG welding machine combines MMA welding and MIG welding into one unit. Flux cored wire or solid wire is fed through the welding torch and then into the weld pool, joining the materials together. Materials combined are often carbon steel, ordinary low alloy steel and stainless steel.

The MIG welding machine features a high welding efficiency, energy conservation and great durability.

Features

• Both regular 2T and semi-automatic 4T modes are supported, accommodating different operating habits. In 2T mode, the operator will need to hold the switch down during the entire cutting process. Once the switch is released, cutting stops. In 4T mode, the operator simply needs to toggle the switch on, let go and then cut and toggle it off when finished.

• In MMA welding mode, a LIFT TIG contact type arc striking is used. The arc striking is done through direct contact between the tungsten electrode and the workpiece, resulting in a short circuit. As a result, the arc will be easily struck, resulting in a soft arc.

• The built-in thrust regulation system is able to prevent arc extinction during the welding process and make the welding current larger as the electrode moves closer towards the workpiece, thereby eliminating welding spatter.

• When the working voltage or current is too high or the welding machine is over heated, the overheat protection, overcurrent protection and low voltage protection features will be automatically used, thus ensuring operation safety.

• The MIG welding machine is designed to work with single phase power supply, making it more suitable to household DIY welding processes.
