 | ◉ Dual welding stations Provides two welding positions from one power source. ◉ 30–630 A output range Adjust the current to suit the electrode size and welding job. ◉ 60% duty cycle at 40°C Supports longer work periods at the specified duty-cycle current. |
◉ Carbon arc gouging capability Adds metal removal for weld repair and joint preparation. ◉ Arc force Helps maintain the arc when the electrode is close to the workpiece. ◉ Acid-coated and basic-coated electrode compatibility Choose from a wider range of electrodes to suit the job. |  |
 | ◉ Overheat and overcurrent protection Helps protect internal components from overheating and excessive current. ◉ Two electrode cable sets and a ground cable included Provides connections for the two welding stations. |
Q1. What is this dual-station MMA welder used for? A1. It is designed for heavy-duty MMA stick welding in fabrication shops, structural steel erection, construction sites, and industrial maintenance – with two independent workstations to boost productivity. Q2. What input voltage does it require? A2. It requires 380V three-phase power – standard in industrial workshops and job sites. Q3. What is the output current range? A3. The output current is adjustable from 60A to 630A, covering light repair to heavy structural welding. Q4. What electrode sizes are supported? A4. It supports 4.0mm, 5.0mm, and 6.0mm electrodes – designed for heavy-gauge welding tasks. Q5. What welding thickness can it handle? A5. The recommended welding thickness range is 0.8mm to 30mm – from thin sheet metal to heavy plate. Q6. What does "dual-station" mean? A6. Two independent welding stations can operate simultaneously from one power source. This allows two welders to work at the same time, effectively doubling workshop productivity without doubling power consumption or floor space. Q7. What is the duty cycle? A7. The rated duty cycle is 60% at 630A, allowing continuous welding for 6 minutes in a 10-minute cycle at maximum output – built for long production runs and heavy repair jobs. Q8. What technology does it use? A8. It uses IGBT module technology with 85% efficiency, delivering stable arc performance, reduced power consumption, and consistent output for industrial applications. Q9. How heavy is the machine? A9. The net weight is 28.8kg, and the package weight is approximately 31.4kg – a robust industrial-grade build. Q10. Do you offer OEM or private label services? What is the MOQ? A10. Yes, OEM and ODM services are available for distributors, contractors, and industrial buyers. MOQ is negotiable – please contact us to discuss your requirements. |
