7. Maintenance
CAUTION: Do not file oxidation attached on the tip. This will shorten the tip lifespan.
Inspection
-
Soldering tip inspection
Measure the resistance between the heating element and sensor, and if the measured value is abnormal, replace the tip. The normal resistance values are as follows:
T39: 5.7 Ω ±10% (at room temperature) T50: 8.0 Ω ±10% (at room temperature)
For the measurement location, see "8. Troubleshooting"
-
Ground line inspection
Unplug the iron connection cord from the station.
Disconnect the power plug from the power outlet and measure the following resistance.
(1) Power cord
(2) Resistance between the tip and the plug (Pin 13) of the iron connection cord
For both, the normal resistance is <2 Ω (at room temperature). If the resistance is abnormal, replace the power cord or the iron connection cord.

Daily maintenance
| Setting temperature | Using the product at a temperature that is higher than necessary can accelerate tip deterioration and damage parts that are susceptible to heat. Use the lowest temperature whenever possible. |
| Before beginning work | Perform a visual check of the tip. Replace it if it is bent or considerably worn. Use the cleaning sponge to wipe off any oxidation or old solder from the tip. Impurities on a circuit board can result in poor soldering. |
| When pausing work | Use sleep mode instead of leaving the handpiece set to a high temperature for a long period of time. This prevents tip oxidation which helps to maintain workability, which can extend the tip lifetime. Turn off the power switch when not using the product for a long period of time. (See "■ Pausing work (sleep mode)" in "4-3. Operation") |
| After finishing work | Thoroughly clean the tip with the cleaning sponge and then coat it with new solder. Doing so can prevent oxidation of the tip. |
Periodic maintenance
-
Tip
Wear and tear on the tip will vary due to the operating temperature as well as the quality and amount of solder/flux used. Maintenance should be performed based on what suits your usage.
(3) Turn the power ON.
(4) Set the temperature to 250ºC (482ºF)
(5) Once the temperature is stable, use the cleaning sponge to wipe the tip.
(6) If there is any black oxidation on the solder plating, apply new solder containing flux and then wipe it off with the cleaning sponge. Repeat this process until the oxidation is removed. Afterward, coat it with new solder.
(7) Turn the power off and remove the tip once it has cooled. If you find flux, debris, and other particulates on anything other than the end of the tip, wipe it off with industrial alcohol. -
Handpiece
Remove flux, debris, and other particulates adhering to
the nipple. It may cause contact failure inside the handpiece
-
Iron Holder
Press down the release button and remove the iron holder base, then clean the collected solder waste from the iron holder.
Rotate the cleaning wire as need to a clean side where solder is not accumulated
8. Troubleshooting

| [C - E] is displayed |
Is an incompatible soldering iron connected? Has the handpiece plug been removed? |
| [H - E] is displayed |
Is the heat capacity of the tip too small for the object to be soldered? Is the set value for the low temp alarm too small? |
| [H S E] is displayed |
Is the tip an applicable genuine tip? Turn off the power switch, insert an applicable genuine tip, and turn on the power switch again. If the problem persists, replace the tip |
| [S - E] is displayed |
Is the tip fully inserted? Is the heating element/sensor disconnected? |
| [- - -] is displayed |
Is there a strong noise source around the soldering iron? Move the soldering iron away from the noise source, or use other circuit for the power. |
| Cannot get solder on the tip |
Is the tip setting temperature too high or too low? Is there any oxidation on the tip? |
| The tip temperature is too high/low |
Is the offset value entered correct? Measure and adjust the value. (See "■ Tip temperature correction (offset)" in "4-3. Operation") |
