ZX7-630DH Inverter DC Arc Welding Machine:
ZX7-630DH Inverter DC Arc Welding Machine Introduction
Advance inverter technology is employed with imported IGBT module. Quick dynamic response, excellent performance and high reliability. Make it meet all quality welding requirements.
Dual IGBT module technology make the performance better and more stable. Higher duty cycle can be gotten to save the energy.
Compare to the traditional machine, No-load loss is less than 100W, saving 50% electricity.
Suitable for low carbon steel, medium steel, alloy steel and other ferrous steel. Available for the carbon arc air gouging and reinforcement bar joints.
It is widely used in the welding and field operations of petroleum pipeline, chemical industry, shipbuilding, electric construction, nuclear power, and war industry, industrial installation, bridge construction and other industries.
Light weight, small size, high efficiency, and energy saving.
Suitable for 8-32mm reinforcement bar joint.
