Technical Features & Performance Advantages
High-Current Precision Control: Utilizing a reinforced IGBT inverter system, the 3150-2 achieves surgical arc precision even at high amperages, preventing undercutting in large-diameter applications.
100% Duty Cycle Performance: Engineered with an enhanced industrial-grade cooling tunnel, ensuring non-stop operation during the most grueling high-intensity welding shifts.
Dual-Operator Independence: The dual-core architecture ensures that two guns can operate at full capacity simultaneously, maintaining stable arc strike without any voltage drop between operators.
Military-Grade Durability: Features a vibration-dampened chassis and IP23-rated protection, allowing the machine to withstand the harsh vibrations and dust of heavy industrial sites.
Dynamic Pilot Arc Striking: Features an optimized pilot arc control that guarantees a 100% success rate on oxidized or rusty steel surfaces, significantly reducing prep time for bridge refurbishment.
Self-Diagnostic Logic: Built-in microprocessor-based monitoring that tracks internal temperatures and phase balance in real-time, providing instant error code feedback to prevent equipment damage.
High-Speed Railway
The professional choice for high-intensity railway infrastructure. Its dual-gun capability effectively doubles construction speed, providing consistent 3150A power for massive structural steel plates and rail base fixings.
Large-Scale Bridges
Rugged IP23 design, ideal for demanding bridge construction. Welds up to Φ32mm studs in single-gun mode with precision, while the dual-core system enables simultaneous welding to handle heavy-duty shear connectors efficiently.
High-rise Buildings
Optimized for skyscrapers and complex steel deck construction. Delivering a massive 120KW capacity, it ensures 100% duty cycle for rapid, continuous welding of large-scale embedded parts and composite floor structures.
Shipbuilding
Ultimate solution for heavy-duty shipbuilding and offshore platforms. Features H-class insulation and IP23 protection, allowing two operators to weld large-diameter connectors simultaneously on thick marine steel with absolute stability.
