the production process. Lead free solder alloys require a working temperature of 30
℃
(54
℉
) higher than previous generation electrical soldering. The working temperature of solder is
detailed below and can vary from manufacture to manufacture.
Melting point 220
℃
(428
℉
)
Normal operation 300-360
℃
(572-680
℉
)
Production line operation 360-410
℃
(680-770
℉
)
When the soldering iron’s working temperature is set within the parameters suitable for the type of
soldering being used, a good joint assured. Too low of a temperature will slow the rate of solder flow
while a high temperature setting might burn the flux in the solder and emit a heavy, white smoke
resulting in a dry joint or permanent damage to the printed circuit board (P.C.B) and may also shorten
tip life.
IMPORTANT
: The temperature above 410
℃
(770
℉
) is not recommended for normal soldering
functions, but can be used for short periods of time when high temperatures are required.
DESOLDERING
Recommended tip working temperatures are detailed below and can vary from joint to point.
Operation for small joint 320
℃
- 360
℃
(608
℉
- 680
℉
)
Operation for larger joint 370
℃
- 400
℃
(698
℉
- 752
℉
)
Too low of a temperature will slow the flow rate of solder and may clog the tip. Too a high
temperature may burn the P.C.B.

2. Decrease temperature: By pressing“▼” key, the same procedure as above.
PARAMETER SETTING:
1. Press “SET” key and hold for at least 3 seconds until display shows“— — —”
sign then release the “SET” key. The sign “— — —” starts to flash and reminding the user to input
the mode lock password “010” (fixed). If the user inputs the same number as “010”, the unit will
enter the modes selection procedure, otherwise, the unit will be back from the current mode
automatically.
