This guide for the Gordak 952 (and variants like 952-V or 952-A) provides essential setup, maintenance, and basic troubleshooting steps based on official user manuals and repair resources. 1. Critical First-Time Setup Before plugging in your station for the first time, you perform this step to avoid damaging the unit: Remove Pump Screws : Locate and remove the three securing screws
on the bottom of the machine. These are for transport only; leaving them in will cause excessive vibration, noise, and potential pump failure. 2. Operating Instructions
: Connect the handle before turning on the power to prevent electric shock. Automatic Cooling
: When you turn off the hot air switch, the unit enters a "cooling program". Do unplug the machine until the temperature drops below
and the air pump stops automatically. This protects the heating element from heat-soak damage. ESD Safety
: Ensure the station is connected to a grounded outlet to prevent static discharge on sensitive components. 3. Maintenance: Replacing the Heating Element Gordak 952 Service Manual
If your hot air gun or soldering iron stops heating, the element likely needs replacement: Disassemble the Handle : Unscrew the securing screws (typically 3) on the handle. Remove the Tube
: Carefully slide off the steel pipe and mica heat insulator. Unplug the Element
: Release the ground connection and unplug the old heating element. Install New Element
: Insert the new element carefully, ensuring correct polarity of the sensor leads (4 leads total). Reassemble
: Reverse the steps, ensuring the quartz glass and insulation materials are replaced correctly. 4. Troubleshooting Common Issues Possible Cause No Display / Won't Power On Blown fuse or MCU power failure
Check the 5V supply on the microcontroller and the main fuse. Air Blows but No Heat Broken heating element or failed Triac
Check the heating element for continuity or inspect internal Triacs. Loud Vibration Transport screws still installed Remove the 3 screws from the bottom of the unit. Erratic Temperature Faulty sensor or PID control issue
Verify sensor lead connections in the handle or check control circuit board. Official Documentation & Schematics
The Gordak 952 Go to product viewer dialog for this item. is a popular, ESD-safe 2-in-1 soldering and hot air rework station commonly used in electronics repair. While a single, unified "Service Manual" in the traditional sense can be difficult to find, the technical community has extensively documented its internals and common fixes. Core Specifications & Features
Dual Functionality: Features independent soldering and hot air stations with separate LED digital displays.
ESD Safe Design: Designed for sensitive electronics assembly and rework.
Independent Operation: Both the soldering iron and the hot air blower can be used simultaneously without interference. Internal Schematic & Layout
For those looking to repair the unit, schematics are often provided as image files rather than formal PDFs.
Power Supply: The PSU typically uses half-wave rectification for +5V and -5V rails and full-wave for the Vacuum Fluorescent Display (VFD) drive voltage. Schematic Access : You can find circuit diagrams for the Gordak 952
on Elektrotanya, which hosts the station's electrical schematics.
Critical Safety Note: Repairing these units involves high-voltage components. Always ensure the device is unplugged before opening to avoid fatal electrical shock. Common Maintenance & Known Issues
Phantom Power Draw: A known design quirk is that even when turned "off," the internal pump and transformers may remain active. Users often perform a "power-off mod" to intercept the main power wires and truly shut the system down.
Cool-Down Cycle: The original design uses the air pump to cool the blower after it is turned off; disrupting this cycle prematurely can damage the heating element.
Component Longevity: The electrolytic capacitors used in some models are noted for having high failure rates. Replacing these with high-quality, branded caps (e.g., Nichicon or Panasonic) is a common reliability upgrade.
Disassembly: Step-by-step guides for taking apart the Gordak 952 are available for those needing to access the internal PCB. Repair Resources
Community Boards: For specific troubleshooting, the EEVblog forum offers expert discussions on failure modes.
Manual Repositories: Sites like Elektrotanya allow users to upload and download relevant repair information.
When performing any maintenance, it is essential to follow standard safety protocols for high-voltage electronics. This includes using insulated tools, wearing appropriate eye protection, and ensuring all capacitors are fully discharged before touching internal components.
For further guidance, consulting with a qualified electronics technician is recommended if the repair involves the main power circuitry or internal transformers.
Part 7: Where to Find Replacement Parts
Using your service manual’s bill of materials (BOM), order from these suppliers:
- Triac: BT136-600E (replace with BTA16 for higher durability).
- Optocoupler: MOC3021 (non-zero-crossing type – critical).
- Air pump membrane: Generic 24V diaphragm pump (size 55x45mm).
- Heating element (air): 220V 700W ceramic core (length 52mm, OD 14mm).
- Soldering iron heater: A1321 4-wire type (not A1322).
Avoid universal "Gordak 952 repair kits" on AliExpress – they often mismatch voltage.
Why Do You Need the Service Manual?
Unlike modern devices that are often "throw-away" technology, the Gordak 952 is repairable. However, opening the unit reveals a PCB that can be confusing without a map. A service manual provides:
- Exploded Views: Identifying part numbers for replacement handles, heating cores, and nozzles.
- Schematics: Essential for tracing why a heating element isn't getting power or why the temperature display is erratic.
- Calibration Procedures: If you’ve replaced a potentiometer or a sensor, you need to know how to recalibrate the temperature to ensure you aren't cooking your sensitive components.
Final Recommendation
If you own a Gordak 952, obtaining a service manual (even an unofficial one) is highly recommended. Pair it with basic tools (digital multimeter, soldering iron) to significantly extend the life of your rework station. For critical repairs, also check the heating element’s resistance (typically 50–100 ohms for the heater, 1–2 ohms for the sensor) and ensure proper grounding for ESD safety.
Note: Always disconnect mains power before opening the unit, and be aware that internal capacitors can retain dangerous voltage.

Temperature Control Loop
- 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.
Power Supply Section
- Transformer T1: Primary 110/220VAC; Secondary 24V (for iron/hot air heater via triac) + 12V (for fan/pump) + 5V (for logic via 7805 regulator).
- Common failure: Thermal fuse hidden inside the primary winding (opens – no display).
