Description
With its industrial-grade 5-PCB architecture and 1+2+3 phase compatibility (220V/380V/415V), the Weldtron ARC400K is the ultimate multi-phase inverter. With six 400V 560uF capacitors, four 40N120 IGBT modules, and four 8040 high-power diodes, it provides a reliable 400A output for even the most demanding electrodes up to 10mm in diameter. During production runs, the enormous 12038 fan guarantees constant cooling. This welder, which weighs 9 kg and has a roomy 425x215x375mm chassis, is used for major infrastructure projects, bridge construction, and shipbuilding.
Features
:- On construction sites, universal 1+2+3 phase operation removes power source constraints.
- With component-level serviceability, the industrial 5-PCB layout optimizes uptime.
- Unmatched arc force and penetration are provided by four 40N120 IGBTs (1200V/40A).
- Continuous high-current rectification is handled by four 8040 industrial diodes.
- There is complete ripple suppression thanks to six 400V 560uF capacitors.
- The heavy-duty 12038 axial fan maximizes airflow while rejecting workshop dust.
- 10mm electrode welding is supported by Extreme Duty Cycle without thermal shutdown.
- Sticking on heavy mill scale is prevented by advanced arc force adjustment.
- Phase imbalance and overloads are prevented by a complete protection package.
Applications
:- Construction of maritime structures and hull plating for ships.
- Construction of high-rise structural steel bridges.
- Fabrication of boilers and heavy pressure vessels.
- Repair of earthmoving equipment and mining draglines.
Usage
:- Choose the best phase configuration: 415V for production, 380V for fabrication, and 220V for repair.
- Present configurations: 320-400A (8-10mm electrodes) and 200-280A (5-6mm).
- For optimal deposition rates, keep the arc length between 5 and 8 mm at a 75° angle.
- Use an industrial fan to run continuously without experiencing thermal cycling.
