Introducing MZS-5 Double-Arc Double-Wire Welding Tractor
Introducing MZS-5 Double-Arc Double-Wire Welding Tractor
The all-new MZS-5 Medium Double-Arc Double-Wire Submerged Arc Welding Tractor sets a new benchmark for automated welding in heavy fabrication. Engineered for superior performance, this tractor combines stable operation, excellent weld appearance, and user-centric innovations to meet the toughest demands of steel structure, bridge, shipbuilding, boiler, and industrial furnace applications.

Outstanding Features for Real-World Welding
The MZS-5 is designed for easy mobility without compromising stability. Its low center of gravity ensures rock-solid performance even on uneven surfaces, while the small track and steel walking wheels guarantee smooth, reliable travel. The flexible welding head can be adjusted quickly and covers a wide range of positions, making it highly adaptable to complex joints.
A key highlight is the dual-drive wire feeding mechanism, which delivers exceptionally smooth wire feeding with high thrust – eliminating stalls or interruptions during long seams. The digital control technology provides rapid response and precise adjustment of welding parameters. Operators will appreciate the manual wire retraction/feeding button on the controller, plus an automatic stop function that activates when the welding contact touches the workpiece, enhancing both safety and ease of use.
Wide Application Scope
The MZS-5 excels at welding carbon steel, alloy steel, stainless steel, and other metal materials. It is already being adopted for steel structure construction, bridge girders, locomotive frames, ship hulls, pressure vessels, boilers, and industrial furnaces. Whether in shop fabrication or on-site assembly, this tractor boosts productivity while delivering consistent, high-quality welds.
