The use and maintenance of the soldering iron tip.
(A) caused by the soldering iron tip does not stain the tin, the main reasons are the following points, please avoid as far as possible.
(1) The temperature is too high, more than 400 ℃ easy to make the tin surface oxidation.
(2) The use of the tin surface is not all tin. www.dgjs123.com
(3) Too little flux when soldering; or use active flux, will make the surface oxidize quickly; water-soluble flux at high temperature corrosive will also damage the soldering iron head.
(4) The sponge used to wipe the soldering iron head is too high in sulfur, too dry or too dirty.
(5) Contact with organic matter such as plastic; lubricating oil or other compounds.
(6) Tin impurity or tin content is too low.
(B) the use of the soldering iron head should be noted and maintenance methods.
(1)Remove the residual oxides, dirt or flux on the iron head before sending power to the iron head every day; and clear out the impurities in the heat generating body to prevent the iron head from jamming with the heat generating body or sleeve. Lock the iron head at any time to ensure that it is in the appropriate position.
(2) When using the temperature first set up in the first 200 ℃ preheating, when the temperature reaches and then set to 300 ℃, to reach 300 ℃ must be real-time addition of tin in the soldering iron head before the end of the tin part, once stabilized for 3 ~ 5 minutes, that is, in order to test the temperature whether the standard, and then set to the required working temperature.
(3) When soldering, do not pick or squeeze the soldering iron tip to be soldered objects, do not use friction welding, so it does not help the heat conduction, and there is a risk of damage to the soldering iron tip.
(4) Do not rub the iron tip with rough surface objects.
(5) Do not use chlorine or acid flux.
(6) Do not add any compounds to the tinned surface. Electrician's World
(7)When not in use for a long time, lower the temperature to below 200℃, and add tin to protect the tip of the soldering iron, do not wipe; only when soldering can be wiped on a wet sponge, and then dabbed with new tin on the tip part.
(8) After the day's work, no welding will be wiped clean and re-dip the tip of the iron on the tip part, and will be stored in the iron on the shelf and the power off.
(9) If the tin surface has been oxidized can not be tin, or due to flux caused by the oxidized film becomes black, with a sponge can not be removed, can be used to 600 ~ 800 mesh sandpaper gently wipe, and then use the inside of the flux of the tin wire around the tin surface of the wiped, to be warmed up and then re-tinned after the tin contact melting.
