Manual [work]: Gordak 952 Service

Adhering to a regular maintenance checklist prevents unexpected downtime and extends the operational life of the station's consumables.

Check thermocouple continuity inside the handle. Replace element if open loop. Burnt hot air heating element or blown triac.

For those looking to repair the unit, schematics are often provided as image files rather than formal PDFs. Gordak 952 Service Manual

The is a widely used dual-function rework station that combines a hot air gun and a soldering iron . Over years of heavy use, components like heating elements, thermal sensors, and triacs can wear out.

Unbolt the pump and drop in a matching 220V/110V universal diaphragm replacement pump. 5. Temperature Calibration Guide Burnt hot air heating element or blown triac

Desolder and test the primary triac (e.g., BTA16) for a collector-to-emitter short. Blown fuse, dead pump coil, or faulty potentiometer.

Turn on the hot air gun and set the digital display to . Let the airflow stabilize for two full minutes. Over years of heavy use, components like heating

The 24V AC secondary wind of the transformer is rectified via a diode bridge and smoothed by an electrolytic capacitor to establish a stable DC voltage rail (typically +12V DC via a linear regulator like the LM7812 or LM7805) to supply the operational amplifiers and display logic. Temperature Feedback Loops

The AC voltage driving the hot air heating element is gated by a Triac (often a BTA12 or BTA16 ), isolated via an optocoupler (like the MOC3041 or MOC3021 ).

Turn the trimmer gently until the external thermometer reads exactly 300°C. Hot Air Calibration Set air flow to medium and temperature to 350°C.

Using a non-conductive ceramic adjustment tool, slowly turn the internal trimmer potentiometer:
