如何檢查發熱元件和組裝電線破損
拔出插頭，測試連接插頭的腳與腳之
間的電阻值如下:
如果“a”與“b”之間的電阻值有異
於上表電阻值，需更換發熱元件（傳
感器）和/或電線。請按照程序1和2進
行。如果“c”電阻值大於上表電阻
值，則要用砂紙或鋼絨輕輕擦除下圖
所示部位的氧化層。
a. 第4腳與第5腳之間(發熱元件)
2.5-3.5歐姆(正常)
b. 第1腳與第2腳之間(傳感器)
43-58歐姆(正常)
c. 第3腳與焊鐵頭之間
2歐姆以下

。
2. 向反時針方向扭開套頭
④
，從焊鐵中拉出套頭。
3. 從手柄

中取出發熱元件
⑥
和電線
⑪
（向著焊鐵頭方向
拉出）。
4. 從D形套中拉出接地彈簧
⑤
。
當發熱元件回復到室溫時測量:
1. 發熱元件電阻值（紅色）2.5-3.5歐姆
2. 傳感器電阻值（藍色）43-58歐姆
如果電阻值反常，更換發熱元件。
關於更換程序，請參閱更換部件內的說明書。
更換發熱元件後，請進行以下事項。
1. 測量第4腳和第1或第2腳之間，第5腳和第1或第2腳之間
電阻值。如果不是∞，則是發熱元件和傳感器受觸及，
這將會損壞印刷電路板。
2. 測量“a”“b”“c”電阻值以確定引線未被扭曲，而接
地彈簧也連接妥當。

Tip Care and Use
D. Turn on the Power Switch.
The heater lamp blinks on and off when the tip
temperature reaches the set temperature. The unit is
now ready to perform soldering work.
For greater convenience, and soldering efficiency, two
stations can be securely stacked as shown.
CAUTION
The soldering iron must be placed in the iron holder
when not in use.
Tip Temperature ----------
Cleaning ---------------------
When Not in Use ----------
After Use --------------------
High soldering temperatures can degrade the tip.
Use the lowest possible soldering temperature.
The excellent thermal recovery characteristics ensure efficient and effective
soldering even at low temperatures.
This also protects the soldered items from thermal damage.
Clean the tip regularly with a cleaning sponge, as oxides and carbides from the
solder and flux can form impurities on the tip.
These impurities can result in defective joints or reduce the tipʼs heat conductivity.
When using the soldering iron continuously, be sure to loosen the tip and remove
all oxides at least once a week.
This helps prevent seizure and reduction of the tip temperature.
Never leave the soldering iron sitting at high temperature for long periods of time,
as the tipʼs solder plating will become covered with oxide, which can greatly reduce
the tipʼs heat conductivity.
Wipe the tip clean and coat the tip with fresh solder.
This helps prevent tip oxidation.
Maintenance
Inspect and Clean the Tip
CAUTION
Never file the Tip to remove oxide.
1. Set the temperature to 250°C (482°F).
2. When the temperature stabilizes, clean the tip with the
cleaning sponge and check the condition of the tip.
3. If there is black oxide on the solder-plated portion of the
tip, apply new solder (containing flux) and wipe the tip on
the cleaning sponge. Repeat until the oxide is completely
removed. Coat with new solder.
4. If the tip is deformed or heavily eroded, replace it with a new
one.
Calibrating the Iron Temperature
The soldering iron should be recalibrated after
changing the iron, or replacing the heating
element or tip.
1) Connect the cord assembly plug to the receptacle on the
station.
2) Set the temperature control knob to 400°C (750°F).
3) Turn the power switch to ʻONʼ and wait until the temperature
stabilizes. Remove the CAL pot plug.
4) When the temperature stabilizes, use a straight-edge (-)
screwdriver or small plus (+) screwdriver to adjust the
screw (market CAL at the station) until the tip thermometer
indicates a temperature of 400°C (750°F). Turn the screw
clockwise to increase the temperature and counterclockwise
to reduce the temperature. Replace the CAL pot plug.
* We recommend the HAKKO 191/192 thermometer for measuring the tip
temperature.
