Main Features
100 % duty‑cycle rating (at ambient temperature of 40 °C)
Polarity selection and parameter setting via front‑panel controls enables easy switching among four welding processes.
Adopts square‑wave control technology to deliver high arc‑starting success rate and stable arc combustion.
Three AC output parameters including frequency, waveform balance and DC offset can be adjusted independently.
Power source parallel‑control technology allows the output capacity to be multiplied.
Multi‑unit power‑source AC phase‑control technology reduces mutual arc interference during multi‑wire and multi‑arc welding.
Product Applications
Primarily applied to submerged‑arc welding processes such as single‑arc‑single‑wire, dual‑arc‑dual‑wire and multi‑arc‑multi‑wire welding.
Satisfies high‑current, high‑efficiency welding requirements for thick plates of various steel grades.

Widely used in steel‑structure construction, heavy‑duty pressure‑vessel fabrication, spiral‑steel‑pipe manufacturing, power‑generation equipment, locomotive & shipbuilding, and large cast‑forged components.
