Description
The Weldtron ARC250K uses a sturdy 5-PCB architecture and advanced 1+2 phase operation (compatible with 220V and 380V) to generate 250A of output. It offers steady arc performance for 2.5-6.0mm electrodes using four 45N120 IGBT modules, four 6030 diodes, and four 400V 680uF capacitors. Dual knobs provide accurate current/voltage regulation, and the potent 9238 high-CFM fan guarantees constant cooling. By reducing open-circuit voltage, VRDs (Voltage Reduction Devices) improve safety. With dimensions of 320x164x295mm and a weight of under 5.1 kg, it is perfect for professional welders who want dual-voltage capability.
Features
:- Both 220V single and 380V two-phase power sources are supported by the 1+2 phase input.
- 5-PCB modular architecture makes component replacement easier and increases reliability.
- Smooth high-frequency arc control is provided by four 45N120 IGBTs (1200V/45A).
- Efficient rectification with low heat is ensured by four 6030 high-current diodes.
- Stable filtering for ripple-free output is provided by four 400V 680uF capacitors.
- During prolonged operation, the high-performance 9238 axial fan keeps the temperature at its ideal level.
- Two control knobs allow for accurate voltage and amperage adjustment.
- For safer handling, the VRD safety switch lowers the open-circuit voltage.
- Arc ignition and electrode release are improved by hot-start and anti-stick features.
Applications
:- Structural framework welding and heavy steel fabrication.
- Equipment repair and maintenance for industrial plants.
- Substantial maritime fabrication and shipbuilding.
- Large-scale infrastructure building initiatives.
Usage
:- For maintenance, switch to 220V single phase; for production, switch to 380V two phase.
- Current knob: 190-250A (5.0-6.0mm electrodes), 110-170A (3.2-4.0mm).
- For safe handling, turn on the VRD switch; to weld, detach it.
- Keep the arc length between 3 and 5 mm; fine-tune the arc characteristics using the voltage knob.
