Description
With two 75A/1200V IGBT modules, the Weldtron ARC-400M's industrial-grade modular IGBT architecture is optimized for 3-phase 415V operation, providing 400A continuous output. This welder uses a large 12038 cooling fan, five 8040 high-power diodes, and a 200uF 800V CBB capacitor to power 6.0–10.0mm electrodes in production settings. While VRD safety lowers open-circuit voltage, the double digital display offers accurate amperage/voltage monitoring. Secure high-current connections are guaranteed by LUG connectors. It is designed for major infrastructure projects, shipyards, and structural steel production. It weighs 17.3 kg and is 525 x 265 x 475 mm.
Features
:- Unmatched arc force and penetration control are offered by dual 75A 1200V IGBT modules.
- Continuous high-amperage rectification is handled by five 8040 industrial diodes.
- A 200uF 800V CBB capacitor produces a steady arc with little ripple.
- The massive 12038 high-volume fan maximizes airflow while rejecting industrial dust.
- Current and voltage characteristics are displayed in real time on a double digital display.
- The Voltage Reduction Device (VRD) switch improves operator safety when handling.
- Cable loosening during vibration is prevented with heavy-duty LUG connections.
- Replacing individual components without completely disassembling is made possible by modular design.
- 10mm electrode production welding is supported by the extreme duty cycle.
Applications
:- Welding structural members and heavy plates for shipbuilding.
- Manufacture of oil rigs and offshore platforms.
- High-rise beam welding and heavy bridge girder.
- Repairing boiler and power production turbine components.
Usage
:- For a secure connection, use LUG terminals to connect to a 415V three-phase supply.
- Turn the VRD switch on for safe handling and upkeep and off for welding.
- Set current: 380-400A maximum (10mm electrodes), 250-350A (6-8mm).
- During operation, keep an eye on the dual display; for thick sections, keep the arc length between 6 and 10 mm.
