Q1. What input voltage does this MMA welder require?

A1. It requires 380V three-phase input power, making it suitable for industrial workshops, fabrication facilities, and construction sites.

Q2. Is this welder suitable for heavy-duty industrial welding?

A2. Yes. With up to 300A output, support for 5.0mm electrodes, and a 60% duty cycle, it is designed for demanding industrial welding applications.

Q3. What welding process does it support?

A3. It supports MMA (stick) welding with flux-coated electrodes, making it ideal for fabrication, structural steel work, maintenance, and repair.

Q4. What electrode sizes are supported?

A4. The machine supports 2.0mm to 5.0mm electrodes, covering common requirements for industrial maintenance and structural welding.

Q5. What welding thickness can it handle?

A5. The recommended welding thickness range is 5mm to 20mm, making it suitable for thick steel components and heavy-duty fabrication work.

Q6. What is the duty cycle?

A6. The rated duty cycle is 60% at 300A, allowing continuous welding for up to 6 minutes in a 10-minute cycle at maximum output.

Q7. Does it require shielding gas?

A7. No. MMA stick welding uses flux-coated electrodes and does not require an external shielding gas supply.

Q8. What technology does it use?

A8. The machine features advanced IGBT module technology, delivering stable arc performance, improved efficiency, and consistent welding results.

Q9. What applications is this welder suitable for?

A9. Typical applications include steel structure fabrication, heavy equipment repair, industrial maintenance, construction projects, and manufacturing operations.

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.
