Main Features

• Proprietary penetration control technology allows adjustment of penetration depth withoutchanging current(except ZD7-630HA pro)

• Uses synchronous phase-shifting parallel technology (except ZD7-630HA pro),with outputfrequency of 80kHz,low ripple coefficients for current and voltage,ensuring more uniformwelds and cut seams

• Large margin IGBT and other key components operate at lower temperatures,ensuringreliable continuous operation

• Upgraded from the originalZD7-HAto reduce footprint and improve welding performance

• 100%(40℃ high-duty cycle,ideal for heavy-duty industrial applications

• Features flat or descending characteristic selection

• Multi-functional power supply suitable for submerged arc welding,flux-cored welding,manual welding,carbon arc gouging,and electroslag welding

• IP23S protection rating

• Overheat and undervoltage protection functions
