220V Electric Welding Machine Portable MMA-550 IGBT Technology Digital Display Inverter Welding Machine-Heavy Duty and High Quality

•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.

•IGBT power supply device with unique control mode improves the reliability of welding machine.

•HD digital display: current digital display screen display is more intuitive, LED digital display makes current intensity more intuitive, improves work efficiency, knob adjustment, welding current automatic matching.

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

•Sufficient capacitance: strong resistance to electric fluctuation, strong power storage capacity, ensuring stable current output, more stable current waveform, more stable welding, increasing vertical reactance, stable output, and reducing welding spark splash.

•Industrial heat exchanger: built-in high thermal conductivity metal fin, serrated design, thickened material with good heat dissipation effect, external silent large fan, dual heat dissipation, protect the machine, and improve the service life.

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