5. INITIAL SETUP A. Iron holder 1. Adjust the height of the iron holder to suit, as follows: i. Loosen the adjusting screws. ii. Set the iron holder to the desired height. iii. Tighten the screws. 2. Put the small cleaning sponge in one of the four holes in the iron holder base.
2. Set the iron in the iron holder . 3. Plug the power cord into a grounded wall socket. The Hakko 942 is protected against electrostatic discharge and must be grounded for full efficiency .
CAUTION: CAUTION: Place the iron in the iron holder when not in use. The Hakko 942 is preset at 350 °C. at the factory . Check the temperature setting by pressing the button. The set temperature will be displayed for two seconds.
Factory settings The Hakko 942 comes from the factory with the following values preset: Temperature scale Celsius Auto power shutoff disabled Low temperature alarm setting 150°C Resetting the supervisor/ operator control setting Set temperature 350°C Control card Each Hakko 942 comes with a small card, which inserts in the control slot in the front of the unit.
3. Entering the tens digit • Press the button to set the desired figure. Any value from 0 to 9 can Press the button. be selected. When the desired figure is displayed, press the button to enter . The units digit will begin to flash. 4.
The Hakko 942 has the ability to electronically compensate for the variations due to tip temperature offset. When a soldering tip is changed, the proper offset temperature value should be programmed into the 942.
8. PARAMETER SETTINGS Entering the parameters The Hakko 942 has the following four parameters: 1) °C or °F temperature display selection 2) Auto power shutoff 3) Low-temperature alarm tolerance setting 4) Resetting the supervisor/operator control setting Once the station enters parameter mode, set the parameters in the order shown below.

• If you enter a value exceeding the allowable buzzer will stop. The value is stored in the range shown to the left, you will be brought Hakko 942 as described in the example below: back to entering a value in the hundreds digit. EXAMPLE: If this occurs, re-enter a correct value.
Always clean the soldering tip before use, to remove any residual solder or flux adhering to it. Use a clean and moist cleaning sponge (provided with the Hakko 942) or the Hakko 599 tip cleaner . Contaminants on the tip have many deleterious effects, including reduced heat conductivity , which contribute to poor soldering performance.
Checking Procedure WARNING: Unless otherwise directed, carry out these procedures with the power switch OFF and the power UNPLUGGED. Check for a broken heater or 1. Check for a broken heater or sensor sensor Measure the resistance across this position. Verify the electrical integrity of the heater and sensor .
Low-temperature alarm tolerance Soldering iron error When the Hakko 909 or Hakko 91 1 soldering iron is connected to the Hakko 942 station, will be displayed. NOTE: Only the Hakko 912 iron is to be used with the Hakko 942 station.
11. TROUBLE SHOOTING GUIDE WARNING: • Before checking the inside of the Hakko 942 or replacing parts, be sure to disconnect the power plug. Failure to do so may result in electric shock. The unit does not CHECK : Is the power cord and/or the connection plug dis-...
