Tips
The tip temperature will vary according to the shape of the tip. The preferred method of adjustment uses a tip
thermometer. (See “Calibrating the Iron Temperature” on page 3.)
A less accurate method involves adjusting the temperature control knob according to the adjustment value for each tip.
Example: When using a 900M-T-H tip at 400°C (750°F), the difference between this tip and
a 900M-T-B tip is -20°C (-36°F).
Set the temperature control knob to 420°C (786°F).
Refer to the chart for the correct adjustment values on page 15.
Troubleshooting Guide
WARNING
* Disconnect the power plug before servicing. Failure to do so may result in electric shock.
* If the power cord is damaged, it must be replaced by the manufacturer, its service agent or similarity qualified
person in order to avoid personal injury or damage to the unit.
Problem 1.
The heater lamp does not light up.
Check 1. Is the power cord and/or connecting plug disconnected ?
• Connect it.
Check 2. Is the fuse blown?
• Determine why the fuse blew and eliminate the cause, then replace
the fuse.
a. Is the inside of the iron short-circuited?
b. Is the grounding spring touching the heating element?
c. Is the heating element lead twisted and short-circuited?
Problem 2.
The heater lamp lights up but the tip does
not heat up.
Check 3. Is the soldering iron cord broken?
• Refer to ʻChecking for breakage in the cord assembly.ʼ
Check 4. Is the Heating Element broken?
• Refer to ʻChecking for breakage in the heating element.
Problem 3.
The tip heats up intermittently.

Check 3
Problem 4.
The tip is not wet.
Check 5. Is the tip temperature too high?
• Set an appropriate temperature.
Check 6. Is the tip clean?
• Refer to “Tip Care and Use”.
Problem 5.
The tip temperature is too low.
Check 7. Is the tip coated with oxide?
• Refer to “Inspect and clean the tip”.
Check 8. Is the iron calibrated correctly?
• Recalibrate.
Problem 6.
The tip can not be pulled off.
Check 9. Is the tip seized?
Is the tip swollen because of deterioration?
• Replace the tip and the heating element.
Problem 7.
The tip doesnʼt hold the desired tempera-
ture.

確定保險絲燒斷原因後進行修理，並更換新保險絲。
a.焊鐵內部是否短路?
b.接地彈簧是否觸及發熱元件?
c.發熱元件引線是否扭曲和短路?
故障2: 發熱器指示燈雖亮，但焊鐵頭
不昇溫。
檢查3. 焊鐵電線是否破損?
請參閱“組裝電線破損檢查法”。
檢查4.發熱元件是否破損
請參閱“發熱元件破損檢查法”。
故障3: 焊鐵頭斷斷續續地昇溫時。
→檢查3.
故障4: 焊鐵頭霑不上銲錫。
檢查5. 焊鐵頭溫度是否過高?
重新設定適當溫度。
檢查6. 焊鐵頭是否清理乾淨?
請參閱“焊鐵頭維護和使用”。
故障5: 焊鐵頭溫度太低。
檢查7. 焊鐵頭是否衍生氧化物?
請參閱“檢查和清理焊鐵頭”。
檢查8. 焊鐵是否正確校準?
重新校準。
故障6: 焊鐵頭拆不開。
檢查9. 焊鐵頭是否被緊夾?焊鐵頭是否因鏽污而膨脹?
更換新的焊鐵頭及發熱元件。
故障7: 焊鐵頭未昇溫達所需溫度。
→檢查8.
焊鐵頭
不同款型焊鐵頭的溫度可能有所不同。調節的最理想方法是使用測量焊鐵頭溫度計。（參照第10頁
“校準焊鐵頭溫度”）
除了以上的調節方法外，也可以採用下述方法調節。
利用控溫旋鈕按照各款型焊鐵頭溫度調節。
例如:
當使用900M-T-H型溫度在於攝氏400度（華氏750度）時，與900M-T-B型焊鐵頭
相差20度。因此必須調節控溫旋鈕為攝氏420度（華氏786度）。
請參閱（第15頁正確）溫度調節表:
排除故障指南
警告:
*進行維修之前應關掉電源，否則可能發生觸電事故。
*若電線損壞，應請廠家或其維修服務代理商或類似之合格人士修理，以免發生傷害身體或損壞電
焊臺。
