Q:One of my earphones is broken. I want to weld myself,One problem with me is that the melted tin does not stick to the copper wire when soldering. The soldering tin is stuck on the iron head and the copper wire is not melted

If the new electric iron, need to use sandpaper to wipe off the iron, and then put the hot iron head full of rosin or eat on the tin, soldering paste, until the iron tin eat so far. Then, the welding wire net sand, with a hot iron wire to pressure or soldering paste on rosin. At this time, the wires were filled with tin, and finally the welding was successful. If the wire was on good tin, iron mill two, is good

Q:Can spring be welded with electric iron?

Yes, it's better not to use electric irons to weld batteries and so forth. That requires special spot welders.

Q:How do you make 12V electric irons for direct current?

Find a detachable core, open it, count the power and resistance, find the right electric wire, turn it around and restore it

Q:Can the electric iron of the school solder aluminium products?

This problem should be like this if you want to belong to the welding of aluminum foil, aluminum and other small pieces of fine and thin pieces, can be used for welding or soldering iron, hot air gun, but low wire materials need to use M51 with M51-F welding flux, video can search "Weiouding copper and aluminum wire welding with welding" if is large, you need to use special WE53 liquefied gas as a heat source using porous spray gun

Q:Turn the button on the handle to the left or right, and turn the temperature up

Turn the knob to the right to raise the temperature. When it is used, don't turn the temperature up so as not to burn out the temperature regulating circuit

Q:First iron...... Duoduosuosuo welding after the touch element, scared ~ I suspect this goods fast run...... Will it be broken?

If it takes a long time, it will be bad.The simplest way is to hold the tube with a Tweezer (between the solder joint and the component), and when it is welded, the heat is transferred to the tweezers. This ensures that it will not overheat.

Q:How much is the electric iron???? I want to buy a welding thing.

There are entry-level, ordinary and so on, generally 10 to block, it is better to tile number 450, a good point

Q:How can the shell be welded with an electric iron?

Yes, but note that the power of the soldering iron must be above 50W, because the bullet shell is larger, the heat is easy to drain, the power is small, the solder is difficult, and the specific method of welding1, the need to clean up the welding part, first coated with rosin flux or solder joints, and then use the soldering iron head covered with solder joints to gently rub, the solder can be uniformly adhesion in the solder joints, two parts to be welded are disposed after splicing them with iron head with hot melt, after cooling good welding. I wish you success

Q:HAKKO 936 constant temperature electric iron temperature not constant, how should I do?

Change Luo close try.. The regular regular core is 5--8 yuan

Q:When the welding is done, where is the head of the soldering iron, where the original pin is attached to the circuit board or on the original pin? Then the tin bar is placed on the head of the soldering iron. After melting, he rolls onto the circuit board Total sense of mastery skills

The iron head put the position of the connection in the original pin and circuit board and solder wire (preferably used) is placed on the iron head waiting for him to melt after rolling to the circuit board, because solder wire inside rosin flux, solder joint welding end so smoothly, and then cut off the excess pin can be. Two question: how to suck the tin of the interface? Put on tin suctioner ready to use electric iron? Or reverse the order? Should be the one hand iron hand ready to see the soldering tin suctioner, tin suctioner immediately sucked out of solder, both the first of which one will make the solder cooling wash off or suction is not clean
