Gordak 952

The is a dual-function SMD rework station combining a hot air gun and a soldering iron. This guide consolidates technical service information, troubleshooting steps, and essential maintenance based on official documentation and community repair consensus. 1. Vital Setup: The Transit Screws

  • Sensor: K-type thermocouple (hot air) / A1321 thermistor (iron).
  • Op-amp LM324: Compares setpoint voltage (from front panel pot) to actual sensor voltage.
  • Output: Drives optocoupler (MOC3021) → Triac (BT136) → Heater.
  • Fix: Replace heating element ($3 part) or resolder relay joints.

    Final Recommendation

    • Measure resistance across the heater element. It should read between 40Ω and 120Ω (depending on voltage). Open loop (infinite)? Heater is dead.
    • Measure the thermocouple/Sensor. It should read 1Ω to 3Ω (short). If it reads open, the station will overheat or not heat at all.
  • Recalibrate every 6 months if used daily.

    • Automatic Cooling

    : When turned off, the pump continues to run until the temperature drops below 100°C (or 50°C on some models). Do not unplug the machine while the cooling cycle is active to prevent damage to the heating element. Maintenance & Repair Gordak 952 The is a dual-function SMD rework

    : Release the ground connection and unplug the old heating element. Install New Element Sensor: K-type thermocouple (hot air) / A1321 thermistor
