Excellent details achieve outstanding quality. High frequency magnetic ring transformer with enlarged and thickened copper wire winding for high-frequency voltage stabilization, welding output more stable, large capacity, and standard capacitance with strong resistance to grid fluctuations. Stable output ensures long-term stability of the machine. High power IGBT tube high-frequency inverter, stable output, high efficiency, energy saving, rapid heat dissipation, welding all day long. Strong heat dissipation fan+built-in enlarged and thickened heat sink dual fan heat dissipation, welding more stable
