焊鐵頭的維護和使用

D.  按開開關掣

當焊鐵頭升溫至所設定溫度時,發熱器指示燈
即會閃亮,指示可以進行焊接工作。
為了更方便工作和取得更高焊接效率,可以將
兩臺電焊臺重疊如圖示。

注意:

當不使用時,應將焊鐵放置在焊鐵架上。

溫度過高會減弱焊鐵頭功能,因此應選擇盡可能低之溫度。此焊鐵頭的
溫度回復力優良,較低的溫度也可充分的焊接,可保護對於溫度敏感之
元件。
應定期使用清潔海綿清理焊鐵頭。焊接後,焊鐵頭的殘餘焊劑所衍生的
氧化物和碳化物會損害焊鐵頭,造成焊接差誤,或者使焊鐵頭導熱功能
減退。
長時間連續使用焊鐵時,應每周一次拆開焊鐵頭清除氧化物,防止焊鐵
頭受損而減低溫度。

不使用焊鐵時,不可讓焊鐵長時間處在高溫狀態,會使焊鐵頭上的焊劑
轉化為氧化物,致使焊鐵頭導熱功能大為減退。

使用後,應抹淨焊鐵頭,鍍上新錫層,以防止焊鐵頭引起氧化作用。

保養

檢查和清理焊鐵頭

注意:

切勿用銼刀剔除焊鐵頭上的氧化物。

1.  設定溫度為攝氏250度(華氏482度)。
2.  溫度穩定後,以清潔海綿清理焊鐵頭,並檢查焊鐵

頭狀況。

3.  如果焊鐵頭的鍍錫部份含有黑色氧化物,可鍍上新

錫層,再用清潔海綿抹淨焊鐵頭。如此重複清理,
直到徹底除去氧化物為止,然後再鍍上新錫層。

4.  如果焊鐵頭變形或衍生重秀鏽,必須替換新的。

校準焊鐵溫度

每當更換焊鐵,或替換發熱器、焊鐵頭
後,應重新校準焊鐵溫度。

1.  將電線裝置的插頭插入電焊臺插座。
2.  控溫旋鈕攝定為攝氏400度(華氏750度)。
3.  按開電源,等待溫度穩定後,移去校準計筒狀插

頭。

4.  溫度穩定後,以“-”字或小“+”字螺絲起子旋轉螺

絲(電焊臺誌有CAL字樣的螺絲),直到溫度計顯示
攝氏400度(華氏750度)為止。順時針方向旋轉是昇
溫,反時針方向是降溫。接上校準計CAL筒狀插頭。

* 我廠建議您採用 HAKKO 191/192 溫度計測試焊鐵頭溫度。

Checking for breakage of the heating element and cord assembly

Disconnect the plug and measure the 

resistance value between the connecting 

plug pins as follows.

If the values of ʻaʼ and ʻbʼ are outside the 

above value, replace the heating element 

(sensor) and /or cord assembly. Refer to 

Procedures 1 and 2.

If the value of ʻcʼ is over the above value, 

remove the oxidization film by lightly 

rubbing with sand-paper or steel wool the 

point as shown.

a. Between pins 4 & 5 (Heating Element) 2.5 – 3.5 Ω (Normal)

b. Between pins 1 & 2 (Sensor)

43 – 58 Ω (Normal)

c. Between pins 3 & Tip

Under 2 Ω

1. Broken Heating Element

Disassembling the 907/908

Heating Element (Red) Sensor (Blue)

1.  Turn the nut (1) counterclockwise and remove the tip enclosure 

(2), the tip (3).

2.  Turn the nipple (4) counterclockwise and remove it from the 

iron.

3.  Pull both the heating element (6) and the cord assembly (11) 

out of the handle (12). (Toward the tip of the iron.)

4.  Pull the grounding spring (5) out of the D-sleeve.

Measure when the heating element is at room temperature.

1.  Resistance value of heating element (RED) 2.5 – 3.5 Ω

2.  Resistance value of sensor (BLUE) 43 – 58 Ω

If the resistance value is not normal, replace the heating 

element.

(Refer to the instructions included with the replacement part.)

After replacing the heating element.

1.  Measure the resistance value between 1) pins 4 & 1 or 2 2) 

pins 5 & 1 or 2. If it is not ∞, the heating element and sensor are 

touching. This will damage the P.W.B.

2.  Measure the resistance value ʻaʼ, ʻbʼ, and ʻcʼ to confirm that the 

leads are not twisted and that the grounding spring is properly 

connected.
