Maintenance / Troubleshooting / Application Examples
|The tip is not heated sufficiently. Why?|
|Case 1:||The power cord and/or connection plug are disconnected.|
|Please check the connection point of power cord and/or connection plug.|
|Case 2:||2 possible causes are Blown-heating element/Blown-fuse or Broken PWB.|
|Cause 1||Blown-out heating element due to its lifespan/deterioration|
|Heating element is a consumable part.
It will deteriorate when it was used for a long period of time.
|As for blown-out checking, please follow the instruction manual.
(Please refer to the followings.)
|♦ Checking for heater burnout
Measure the resistance between the plug pins listed below.
If the values differ from those listed below, repalce the heating element.
|Cause 2||Blown-Heating element/Blown-fuse due to twisted lead wires being connected to the tip, or PWB being broken|
|Flux was accumulated inside the nipple so that the nipple and the tip were stuck. When you replace the tip (or loosen the nipple), the tip and nipple turn together, resulting in the lead wires being connected to the tip were twisted.|
|[Tip has twisted lead wires]
Please check if the lead wires are NOT twisted as a following picture.
|[Lead wires of Brand new tip]
The lead wires of a normal tip are straight as a following picture.
1. Please make sure that the nipple and tip do NOT turn together when you tighten the nipple (replace the tip).
2. Clean regularly the attached flux inside Handpiece such as inside the nipple, O-ring, etc. with rubbing alcohol.
|It's time for cleaning when you found that the tip turned along with the nipple.|
|In case of broken PWB, please send it for repair through a distributor.|
