the unit will enter automatically the power off suspend status. It means the heater
power will be cut off and the LED displays “— — —” and flashes. You can wake
it up by pressing “▼” key when you reuse the iron or turn off the main switch and
re-switch on.
7. Fahrenheit and Centigrade (Celsius) temperature selection
When temperature display window shows "F-4" and blinking, press the "SET"
button, at this time ,the system enters the degrees Fahrenheit and Centigrade
temperature selection function, indicating the temperature of the window shows
the current status. Press "▲" or "▼" key to change the temperature selection
status. It expressed as degrees Celsius temperature value if set to “℃”; it shows
as degrees Fahrenheit temperature if set to ℉
WORKING TEMPERATURE
SOLDERING
To meet RoHS requirements, the common 60/40 lead solder alloys are not allowed in
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.
