Gordak 952 Service Manual

The Gordak 952 is a widely used dual-function SMD rework station. It combines a hot air gun and a soldering iron into one analog-controlled bench unit. This service manual provides technical specifications, circuit explanations, troubleshooting steps, and repair guidelines for technicians. Technical Specifications and System Overview

If you buy a generic 858D handle, repin according to this table.

Test the front panel air volume potentiometer. Check for a shorted BT136 TRIAC on the pump control line.

Wait for the temperature to stabilize, then measure the real temperature at the nozzle/tip. Gordak 952 Service Manual

Identifies all resistors, capacitors, diodes, transistors, triacs (e.g., BT136), optocouplers (e.g., MOC3021), and the heating element specs. This aids in identifying burnt or failed parts.

The Gordak 952 utilizes a dual-board or single mainboard layout depending on the manufacturing year. The circuit can be broken down into four primary blocks:

Check all internal silicone tubing connections for tight seals and clear pathways. Calibration Procedure The Gordak 952 is a widely used dual-function

: Critical: You must remove the pump securing screws (shipping bolts) on the bottom of the machine before use to prevent severe mechanical damage.
