How do you get the tin on the new electric iron?
Buy a new electric soldering iron head if it is ordinary red copper, tin after treatment: first to the surface oxidation layer of iron head with sandpaper polishes suitably, to expose the copper color, and the mixture is ready for some rosin solder. Then, the electric heating of the wire is made. When the surface of the iron head becomes yellow red, the iron head is inserted into the mixture of the rosin and the solder rapidly, and a little friction is made, so that the soldering tin is coated with the front end of the iron head.If you buy a new type of advanced iron head, you do not need to pass the tin processing, you can use normally.It should be noted that when soldering tin on the new soldering iron, do not use solder oil or solder paste, nor do you use zinc chloride solution.
Iron did not heat began to melt after the rosin rosin Jiao, Jiao full, and then use the iron head rub until hung tin. Note: the iron head heat through to Jiao rosin late, the head is oxidized.
Buy a new electric iron can take a knife hanging iron head (because of oxide) then insert power plug power be hot temperature is very highAs the temperature up to soldering iron head point point rosin solderPlace the solder on the point where the solder needs to be solderedThen welding in the welding components, attention to speed, or the temperature is too high, easy to burn componentsWhen the electric iron without the iron head above the point (to prevent dry burning solder iron) flux as far as possible the use of rosin solder paste will have little because of corrosion
