Max Φ36mm (Single)

Φ3-24mm (Dual Gun)

Dual Core Tech

Two Independent Systems

Double Efficiency

Construction Speed Up 30%

Large-Scale Bridges

Rugged IP23 design with H-class insulation for extreme bridge sites. It welds massive Φ36mm shear studs with absolute precision, while its dual-core technology enables simultaneous welding to meet the most demanding construction schedules.

High-rise Buildings

The ultimate power for skyscraper steel deck projects. Delivering a massive 150KW input capacity, it ensures stable, high-intensity performance for continuous welding of large-diameter embedded parts, significantly shortening the construction cycle per floor.

High-Speed Railway

Engineered for heavy-duty railway infrastructure requiring rapid output. Its dual-gun system effectively doubles productivity for massive structural plates, providing a consistent 4000A current that ensures perfect penetration and bond strength.

Shipbuilding & Offshore

A powerhouse for heavy-duty shipbuilding and offshore platforms. It allows two operators to weld large-diameter connectors simultaneously on thick marine steel, maintaining superior arc stability even in high-humidity environments.
