MFDC Retrofit & NF/MF Conversion Projects
Upgrade your welding technology without stopping your production line.
NF (50/60 Hz) frequency-based spot welding systems carry significant disadvantages in terms of energy consumption, weld quality, and equipment reliability compared to MFDC (1000 Hz medium-frequency) inverter technology. At ISI-Türkiye, we replace the control and power electronics components with MFDC technology while preserving the mechanical infrastructure of your existing system.
Conversion Scope:
• Assessment and technical analysis of existing NF welding machine
• MFDC inverter and control cabinet commissioning
• Robot/PLC integration and program optimization
• Reconfiguration of welding parameters
• Field tests and commissioning
• Training for operators and maintenance personnel
Achieved Benefits:
✓ 30–50% energy savings
✓ Shorter welding cycle, higher production speed
✓ Improved welding nugget quality and consistency
✓ Reduced electrode wear and maintenance cost
✓ Preservation of existing robot and equipment infrastructure
✓ High efficiency gains at low investment cost
