• Compact design for optimal system integration.
• Integrated process monitoring for quality control.
• Short cycle times due to high output current.
• Feedback up to 20 kHz for fast reaction to weld process fluctuations.
• Optimum feedback with current, voltage, and power mode controls.
• Additional force control via proportional valve.

The MIYACHI PECO ISQ inverter series is available in four performance versions: ISQ20-3k, ISQ20-6k, ISQ20-10k, and ISQ20-20k. These models offer controlled DC inverter current and can be configured with AC or DC inverters. They feature integrated power-on buttons, performance and control electronics, and optional displays.

• Control Modes: Current, voltage, or power feedback control, independently adjustable for each pulse.
• Programmable Weld Schedules: 99 at single axis; 49 per head at dual axis.
• Weld Pulse Control: Includes up slope, weld-time, down-slope, break time, and impulse cycle.
• Current and Voltage Measurement: Integrated and external options available.
• Limit Values: Display with limit exceeding notifications and adjustable tolerance windows.
• Operation: One-button toggle wheel with optional colored AWS3 Display, Profibus, or Ethernet IP.
• EU Certification: CE Compliant.

• Supply Voltage: 3x 400 VAC, ± 10%, PE; optional 3x 230 V.
• Mains Frequency: 50 - 60 Hz.
• Fusing: Delayed fusing options depending on voltage.
• Protection Class: IP30.

• Connected Load: Ranges from 11 kVA to 85 kVA depending on model.
• Switching Frequency: Maximum 20 kHz for ISQ20K-3 and ISQ20K-6; varies for other models.
• Output Frequency: Ranges from 1 to 40 kHz depending on model and configuration.

Resistance welding applications such as stranded wire to coil motor fusing and stranded wire to terminal connections.
