Key Technological Innovations
- Multi-Process Welding Capability
- GTAW (TIG) / GMAW (MIG) Hybrid System – Switch between processes without equipment changes
- Pulsed Wave Control – Reduces heat input by 30% vs. conventional welding
- Boiler Code Compliance – ASME Section I, EN 12952, EN 13445 certified
- Proprietary Hot Wire System
- True Sine-Wave Output– Eliminates magnetic arc blow
- Performance Benefits:
- Deposition Rate: ↑40% vs. cold wire TIG
- Travel Speed: Up to 25 cm/min (narrow-gap welds)
- Defect Rate: <0.5% lack-of-fusion incidents
- Intelligent Arc Voltage Control (AVC)
- Real-Time Torch Height Adjustment (±0.1mm precision)
- Self-Correcting Algorithm – Compensates for:
- Tube ovality variations
- Joint misalignment
- Thermal distortion
- Adaptive Welding Software
- 200+ Preset Programs – Optimized for:
- Material Types (P91, T22, 304H, etc.)
- Joint Configs (Butt, socket, set-on)
- Self-Learning Function – Improves parameters after every 10 welds
