Technical Advantages
- Advanced IGBT Soft-Switching Full-Bridge Inverter Technologywith UC3846-based double closed-loop current control.
- Precise Droplet Transition & Waveform Control Technology (electronic inductance simulation) enabling freely adjustable arc characteristics for diverse welding requirements.
- High-Frequency Power Conversion: Main transformer utilizes ultra-fine grain iron core, enabling inverter frequencies up to 20 kHz.
- Efficient Input Stage: Passive Power Factor Correction (PFC) ensures high power factor with a wide input voltage range (320V-450V).
- Optimized Arc Performance: Features slow wire feed arc starting and anti-sticking functions. Delivers high arc starting success rate, minimal spatter, and fast ignition.
- Robust Wire Feeding: High-torque wire feed motor system ensures stable feeding even under high resistance or with long cables (up to 50m with optional split feeder)
- Enhanced Usability: Selectable self-locking / non-self-locking trigger function facilitates extended welding operations
- Comprehensive Protection & Monitoring: Integrated over-current and over-temperature protection. Full digital display for real-time current and voltage monitoring
- Versatile Application: Triple-function design supports gas-shielded welding, manual electrode (MMA), and specialized turbine maintenance welding (Models 500/630).
