Temperature control/constant temperature soldering iron operation method and instructions
Temperature control/constant temperature soldering iron operation method and instructions 1. Use steps: 1. Confirm that the asbestos is wet. 2. Steps to end use: 3. The most suitable working temperature Using too low a temperature during the soldering process will affect the fluency of soldering tin. If the temperature is too high, it will damage the copper foil of the circuit board and the welding is not complete and unsightly. If there is white smoke or white powder on the surface, uneven and dull, the temperature is too high. Both of the above two situations may cause cold welding or overwrapping. In order to avoid the occurrence of the above situation, in addition to cautious use of tin wire, it is necessary to select an appropriate and correct working temperature. General tin wire melting point 183℃～215℃ (about 361℉～419℉) Note: In the red zone, when the temperature exceeds 400°C (752°F), do not use it frequently or continuously; occasionally use it in large solder joints or very fast soldering, only for a short time. 4. How to use and maintain the soldering iron tip: (1) The temperature is too high, and it is easy to oxidize the tin surface when it exceeds 400℃. (1) Remove the residual oxides, dirt or flux on the soldering iron tip every day before powering on the soldering iron tip; remove impurities from the heating body to prevent the soldering iron tip from jamming with the heating element or sleeve. Lock the tip of the soldering iron at any time to ensure that it is in place. 5.

2. Remove impurities on the surface of the heating tube.
3. Confirm that the soldering iron screws are not loose.
4. Confirm that the 220V power socket is plugged in.
5. Turn the power switch to the ON position.
6. Adjust the temperature setting knob to 300℃. After the heating indicator light goes out, use a thermometer to measure whether the temperature of the soldering iron tip is within 300℃±10℃; then heat to the required working temperature.
7. If the temperature exceeds the range, you must stop using it and send it for repair.
8. Get started.
1. Clean and wipe the tip of the soldering iron and add a little tin wire to protect it.
2. Adjust the temperature setting knob to the lowest temperature that can be set.
3. Switch the power switch to the OFF position.
4. Unplug the power plug.
The following are the appropriate operating temperatures for various soldering work:
Normal working temperature: 270℃～320℃ (approximately 518℉～608℉)
The operating temperature of the production line is 300℃～380℃ (approximately 572℉～716℉)
Tin suction working temperature (small solder joints) 315℃ (about 600℉)
Tin suction working temperature (large solder joints) 400℃ (approximately 752℉)
(1) The main reasons for the soldering iron tip not sticking to the tin are as follows, please avoid as much as possible:
(2) When using, the tin surface is not completely tinned.
(3) There is too little flux during soldering; or the use of active flux will quickly oxidize the surface; the water-soluble flux is corrosive at high temperatures and will damage the soldering iron tip.
(4) The sulphur content of the sponge used for wiping the soldering iron tip is too high, too dry or too dirty.
(5) Contact with organics such as plastics; lubricants or other compounds.
(6) The tin is impure or the tin content is too low.
(2) Precautions and maintenance methods for the use of soldering iron tips:
(2) When using, first set the temperature to about 200°C for preheating, and then set it to 300°C when the temperature reaches 300°C. When it reaches 300°C, add tin to the soldering part of the tip of the soldering iron in real time, until it is stable 3～ After 5 minutes, test whether the temperature is standard, and then set it to the required working temperature.
(3) During soldering, do not force the soldering iron tip or squeeze the object to be welded, and friction welding cannot be used. This will not help heat conduction and may damage the soldering iron tip.
(4) Do not rub the tip of the soldering iron with objects with rough surfaces.
(5) Do not use chlorine or acid flux.
(6) Do not add any compound to the tin surface.
(7) When not in use for a long time, lower the temperature to below 200℃, and protect the tip of the soldering iron with tin. Do not wipe; wipe it on a wet sponge only when soldering, and re-dip new tin on the tip Copies.
(8) After working on the same day, when not soldering, wipe the tip of the soldering iron clean and re-dip the tip with new tin, store it on the soldering iron stand and turn off the power.
(9) If the dipping surface is oxidized and cannot be stained, or the oxide film becomes black due to flux and cannot be removed with a sponge, wipe it lightly with 600-800 mesh sandpaper, and then use a solder wire with flux inside. On the wiped tin surface, heat it up and tin again after the tin touches and melts.
(1) When changing a new soldering iron tip, please make sure that the heating element is cold, so as not to burn your hands.
(2) Turn the nut counterclockwise by hand to remove the sleeve. If it is too tight, clamp it with pliers and rotate it gently.
(3) Remove the debris from the heating body and replace it with a new soldering iron tip. The heating method can be carried out in accordance with the second sub-item (2) of the sixth major item.
(4) If the soldering iron tip is stuck, do not pull it out forcefully to avoid injury to the heating element. At this time, you can spray the stuck part with rust remover and turn it gently with pliers.
(5) If the stuck situation is serious, please return it to the dealer for processing.
Six. General maintenance:
(1) The plastic shell or metal part can be wiped with a scouring oil in the cooling state. Do not intrude into any liquid or allow any liquid to penetrate into the machine.
(3) Do not knock or strike the soldering iron to avoid breaking or damaging the heating tube.
(4) If there is oxide on the soldering iron tip during operation, it must be cleaned and wiped with asbestos immediately.
(5) Asbestos must be kept damp and must be cleaned every 4 hours.
(6) If the soldering iron tip is oxidized, apply 600~800 fine sandpaper to remove impurities, and then warm it with tin; if this method still cannot eliminate the oxidation phenomenon, the soldering iron tip should be replaced immediately.
