This comprehensive service guide provides technical specifications, operational theory, common failure modes, schematic breakdowns, and step-by-step repair procedures. Technical Specifications & Overview

If your station is acting up, check these common fault areas. A. Soldering Iron Not Heating

Disassemble the soldering iron handle and check the continuity of the heating element. If it's open-circuit, it needs replacement. Sensor Issue: The thermocouple sensor may be faulty. Set the temperature to 250ºC, clean the tip

Place the tip of the iron or the nozzle of the hot air gun (positioned 5mm away) onto your thermal calibration probe.

When turning off the hot air switch, let the system automatically run its cool-down cycle. The pump will keep blowing air until the element drops below 100°C. Switching the main power switch off prematurely traps residual heat, which instantly melts the plastic handle casing and destroys the element.

Without the service manual, even simple repairs can become a time-consuming guessing game, potentially causing further damage to the station. the control board

This subsystem operates similarly to the hot air loop but runs entirely on isolated low-voltage power. The 24V AC from the transformer passes through a secondary TRIAC (e.g., BT137). An op-amp monitors the resistance change or millivolt output of the soldering iron's internal sensor, cycling the TRIAC to regulate the iron tip's temperature.

If the tester reads 285°C (15°C too low), slowly turn the respective trimpot with your screwdriver until the external thermometer climbs to exactly 300°C.

The Gordak 952 relies on an analog-driven feedback loop rather than complex microprocessors. This makes it highly repairable. Opening the chassis reveals three main modules: the main power board, the control board, and the diaphragm air pump. 1. The Main Power & Control Circuit

The Gordak 952 is a staple dual-function rework station found on the benches of electronics hobbyists, repair technicians, and hardware engineers worldwide. Combining a temperature-controlled soldering iron and a diaphragm-pump-driven hot air gun into a single chassis, it delivers reliable performance at an accessible price point.
