1250A Automatic Submerged Arc Welder With Welding Tractor For Stainless Steel Description:
The MZ-1250D 1250A Automatic Submerged Arc Welder is a heavy-duty Submerged Arc Welding Machine engineered for high-deposition welding and demanding industrial fabrication applications. Combining Submerged Arc Welding (SAW), MMA Stick Welding, and Carbon Arc Gouging functions into one powerful system, this Submerged Arc Welder delivers exceptional welding efficiency, deep penetration, and superior weld quality for thick steel structures and large-scale manufacturing projects.
Powered by advanced IGBT inverter technology, the MZ-1250D Submerged Arc Welder provides stable arc performance, precise welding parameter control, and reliable operation under continuous heavy-duty workloads. The integrated digital display allows operators to monitor welding current and voltage in real time, ensuring accurate parameter settings and consistent welding results.
Equipped with welding current and voltage preset functions, the machine simplifies setup and improves production efficiency. The package includes an automatic welding tractor, connecting cables, and a 25kg standard wire spool, enabling efficient automatic welding for long seams and large workpieces.
This Automatic Submerged Arc Welding Machine is suitable for welding mild steel, alloy steel, stainless steel, and heat-resistant steel. It is widely used in steel structure fabrication, shipbuilding, bridge construction, pressure vessel manufacturing, wind tower production, pipeline engineering, and heavy industrial fabrication industries.
