ISQ Series - Inverter Power Supply

The ISQ Series - Inverter Power Supply is designed to be used in combination with mechanical, pneumatical or motorised weld heads. It offers process control monitoring with MG3 and with the AWS3 Active Welding System. The AWS3 integrates the process control of all mechanical and electrical parameters, static and dynamic process monitoring, quality analysis with advanced SPC feature and datalogging.

Key features ISQ Series - Inverter Power Supply

  • Compact design for optimal system integration
  • Integrated process monitoring allows for quality control
  • Short cycle times thanks to high output current
  • Up to 20 kHz feedback for fast reaction to fluctuations in the weld process
  • Optimum feedback thanks to current, voltage and power mode controls
  • Additional force control via proportional valve
