Note: Always disconnect mains power before opening the unit, and be aware that internal capacitors can retain dangerous voltage.
Driven by a separate operational amplifier circuit (commonly utilizing an LM358 or similar op-amp) to read the iron's thermocouple feedback and pulse a 24V line to the iron tip. 4.

The Gordak 952 is a versatile and popular tool, but like all electronic equipment, it requires a service manual for proper maintenance and repair. This document is a deep dive into the station's design, providing circuit diagrams, component lists, and systematic troubleshooting guides. Whether you are diagnosing a power failure on a 952V, weak airflow on a base model, or simply need to calibrate the temperature on your 952A, the service manual is your most valuable resource. By understanding its contents and knowing where to find it, you can significantly extend the life of your Gordak 952 and ensure it continues to perform at its best.
Open chassis, inspect the rubber diaphragms for tears. Verify the shipping bolts were removed from pump base. Maintenance: Replacing the Heating Element
The op-amp compares the reference voltage with the amplified thermocouple voltage. If the actual temperature is lower than the setpoint, the op-amp outputs a signal to trigger an optocoupler (e.g., MOC3041). The optocoupler fires the main power TRIAC (typically a BTA12 or BTA16), which sends AC power to the heating element. Once the voltages match, the TRIAC gates off, cycling rapidly to maintain a stable temperature. 3. Soldering Iron Control Loop
Check continuity of the thin thermocouple wires inside the handle cable. Replace heating element core. Faulty speed potentiometer or shorted pump TRIAC.
: Ensure the station is connected to a grounded outlet to prevent static discharge on sensitive components. 3. Maintenance: Replacing the Heating Element
