What temperature range is standardized for thermostatic soldering irons?
I. Steps for use:
1. Make sure asbestos is damp.
2. Remove the impurities on the surface of the heating tube. 3.
3. Make sure the soldering iron screws are not loosened.
4. Make sure the 220V power socket is plugged in. 5.
5. Switch the power switch to ON position. 6.
6. Adjust the temperature setting knob to 300℃, wait for the heating indicator light to turn off, use a thermometer to measure the temperature of the iron head is 300℃±10℃ or less; then heat up to the required working temperature. 7. If the temperature exceeds the range, it must be stopped.
7. If the temperature exceeds the range must stop using, and send to the maintenance.
8. Start to use.
. End of use steps:
1. Clean and wipe the soldering iron head and add a little tin wire to protect it. 2.
2. Adjust the temperature setting knob to the lowest temperature that can be set. 3.
3. Turn the power switch to OFF position. 4.
4. Unplug the power cord.

Optimum Working Temperature
If the temperature is too low during the soldering process, it will affect the smoothness of the solder. If the temperature is too high it will harm the copper foil of the circuit board with incomplete and unattractive soldering. If there is white smoke or white powder on the surface of the uneven surface without luster is the use of too high a temperature. Both of the above situations may cause cold soldering or cladding. In order to avoid the above situations, it is necessary to choose the appropriate and correct working temperature in addition to using the wires carefully.
The following are the appropriate operating temperatures for various types of soldering work.
The melting point of solder wire is 183℃～215℃ (about 361℉～419℉).
Normal working temperature 270℃～320℃ (about 518℉～608℉)
Production line operating temperature 300℃～380℃(about 572℉～716℉)
Suction working temperature (small solder joint) 315℃ (about 600℉)
Suction working temperature (large solder joints) 400℃ (approx. 752℉)
Note: In the red zone, i.e., temperatures exceeding 400°C (752°F), do not use the product frequently or continuously; occasionally, when it is required to be used for large soldering joints or very fast soldering, it should be used only for a short period of time.
