MMA-400/550/600 Portable IGBT Inverter Welding Machine with Digital Display Heavy Duty and High Quality, 220V

Advanced IGBT inverter technology: The welding machine adopts advanced IGBT inverter technology and high-frequency inverter technology, which can weld low carbon steel, welding steel, stainless steel and cast iron. The unique control mode of the IGBT power supply unit improves the reliability of the welding machine.

High-definition digital display: the current digital display screen display is more intuitive, LED digital display, make the current intensity more intuitive, improve work efficiency, knob adjustment, welding current automatic matching.

High-frequency magnetic ring transformer: high frequency stability, saving energy consumption, reducing output voltage ripple, high load rate, strong oxidation resistance.

Sufficient capacitance capacity: strong resistance to electrical fluctuations, strong power storage capacity, to ensure stable current output, more stable current waveform, more stable welding, increase vertical reactance, stable output, reduce welding sparks.

Industrial grade heat deceler: built-in high thermal conductivity metal fins, serrated design, thickened material heat dissipation effect, external silent large fan, double heat dissipation, protect the machine, improve the service life.

Safety: There is a protective device inside to prevent overheating, overcurrent, overload and ensure safe operation.

Portable: This welder has an easy-to-carry handle, compact design, and a body weight of about 1.45KG, so you can carry and store it easier by bringing the welder to work.
