IGBT Inverter vs SiC MOSFET Inverter
IGBT is the industry standard for welding inverters, offering reliability and cost-effectiveness. SiC MOSFET (Silicon Carbide) is newer technology with higher efficiency and switching speed, used in our industrial MIG series.
Overview
IGBT is the industry standard for welding inverters, offering reliability and cost-effectiveness. SiC MOSFET (Silicon Carbide) is newer technology with higher efficiency and switching speed, used in our industrial MIG series.
Advantages Comparison
IGBT
- Proven reliability
- Lower cost
- Widely supported
- Good for most welding applications
SiC MOSFET
- Higher efficiency (less heat)
- Faster switching
- Better arc stability
- Used in industrial MIG for premium performance
Applications
- ✓IGBT: all MMA, standard MIG, TIG welders — covers 90% of welding needs
- ✓SiC MOSFET: industrial MIG series (NBC-350SIC, NBC-500SIC) for high-volume production welding
FAQ
For most welding applications, IGBT is the better choice due to reliability and cost. SiC MOSFET is superior for high-power industrial applications where efficiency matters most.
Both are reliable when properly designed. IGBT has a longer track record in welding. SiC MOSFET is newer but shows excellent longevity in our industrial MIG models.
