The front panel of the HAKKO FX-301B soldering 

pot has the following controls:

  -  Increases the value in the appropriate display 

window.

  -  decreases the value in the appropriate display 

window.

  -  Holding down the button for one second or 

more will enter into the temperature setting 

mode. If the button is otherwise pressed for 

only less than one second, the current set 

temperature will remain displayed. In the input 

mode, establish the entered value and exist 

the data input mode.

  -  Holding down the button for one second or 

more will enter into the offset input mode. If 

the button is otherwise pressed for only less 

than one second, the current offset value will 

remain displayed.

Operation

1. Turn the power switch ON.

2. The temperature set at factory is displayed.

*The temperature was set to 350℃ at factory.

3. The temperature control is started, causing the 

temperature to increase.

NOTE:

The display blinks when the power is turned 

ON or when settings are changed. This 

blinking occurs because the temperature 

control is in progress. The current temperature 

will be displayed in a short time.

6. PARAMETER SETTINGS

2) Setting a solder type

3) Setting the solder pot type

4) Setting the timer

Once you enter the parameter setting mode, the 

setting sequence will start in the following order. 

After all the parameters have been set, the
