Product Description
Product Overview
The NBC-500X / NBC-500A / NBC-500 is an industrial-grade CO₂ gas-shielded welding machine built on a proven IGBT inverter platform with a classic analogue big-board control circuit. Designed for demanding fabrication environments, it delivers stable, reliable performance with comprehensive protection and multi-process capability.
Models covered: NBC-500X | NBC-500A | NBC-500
Key Features
- IGBT inverter with proven analogue control circuit for stable, reliable operation
- Complete under-voltage, over-voltage and over-current protection for safe, reliable operation
- Classic analogue big-board technology: good welding performance and high reliability
- High-voltage slow wire feed arc starting: no wire burn-back at start, no ball at arc end
- Constant-voltage / constant-current output: MIG/CO₂ welding plus multi-process capability
- Crater-fill (burn-back) mode greatly reduces operator fatigue
- Optional extension control cable for welding in narrow or elevated positions
- User-friendly, modern appearance for easier and more comfortable operation
