Technical Features & Performance Advantages
Ultimate Power Penetration: Specifically tuned for large-diameter shear connectors, ensuring a consistent heat-affected zone (HAZ) and maximum bond strength on marine-grade steel.
Intelligent Load Balancing: Features an advanced digital control algorithm that automatically balances power distribution, protecting internal components from thermal overload during peak usage.
Advanced Surge Protection: Equipped with a high-capacity EMC filter, reducing electromagnetic interference and protecting sensitive electronics on the same site power grid.
Reinforced Transformer Design: The internal high-frequency transformer is built with H-class insulation, providing superior heat resistance for continuous 24/7 fabrication environments.
Heavy-Duty Arc Stabilization: Optimized for Φ36mm studs, the control system maintains a “dead-stable” arc column, preventing magnetic blow-out commonly found in deep-groove welding.
Dual-Fan Forced Cooling: Equipped with a high-volume twin-fan system that creates a directional airflow path, ensuring the most heat-sensitive power modules remain at optimal temperatures.
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.
