Tu su tri okolnosti što an električno lemljenje željezo pobjeda't toplina gore.
1. Ispravno install the željezo jezgra jezgra the električno željezo
After some internal grijanje tip električno lemljenje glača are zamijenjeno s new lemljenje željezo jezgri, they are energized for a long time, but the temperature does not go up. Can't even melt tin, the handle is very hot. When checking, if the voltage is normal, you need to remove the soldering iron core to check whether the internal installation is reasonable.
The interno grijanje tip lemljenje željezo je is ista duljina as the the outer tube ljuska. The correct installation method is to keep the end of the soldering iron ; core aligned with the end of the the outer tube, and not indent or protrude. Only by keeping the alignment can the heat be good. to the tip of the soldering iron.
If the soldering iron core is retracted a lot, the installation of the electric grijanje core tends to the handle, which makes the heat koncentrirano on the handle end, and the heat on the soldering iron tip cannot reach the temperature of melting kositar.
2. The ožičenje of the new soldering iron core
An internal grijanje tip lemljenje željezo jezgra was puhano izlaz, i the service life bio ne dugo even after sever zamjene.
The olovo žica of the newly replaced soldering iron core is too short. There is no room for the soldering iron core to expand and contract when it is cold and hot, which uzroci the internal thin resistance wire to be broken when the soldering iron core is Cold and shrinks after the plug is is unplugged.
The correct replacement method: make the lead wire a little longer, 1-2mm, so that it is not easy to burn out. Pay attention to prevent the wire end from being too long to touch the wire, so as not to cause a a short circuit fault.
3. Popravak slomljeno grijanje žica
When the electric soldering iron does not heat up, the broken grijanje žica needs to be popravljeno. In the choice of repair method, the twisting method should not be used.
After the the hot wire or root lead of the electric soldering iron is disconnected, it is is generalno reconnected by twisting method. The disadvantage of this method is is that contact is loose and the contact resistance is large, which may easy cause ignition or thermal fuge.
Improvement metoda: Take out the grijanje žica, first remove the oxide at the joint, then twist it tightly, and then put a little broken glass and electric keramic material (6:1) powder around the joint. Power on a a A Minutes after installation, The Powder Is Melted and Attached To The contacts, it Is Not Easy To Fupe, i It Is Is Durable.
What is the tipično temperatura of a lemljenje željezo?
If it is a tinned electric soldering iron, its maximum temperatura is about 300 degrees, because the melting point of tin is 231,9 degrees, so it is not possible to solder aluminijskih, the talje točka of aluminij is 660,2 degrees, i zavarivanje aluminij treba bio plin zavarivanje.
What is the normal temperatura of a lemljenje željezo?
When the electric soldering iron is soldering different things, the temperature is different, and the temperature is different when soldering copper and soldering iron, depending on the actual situation.
Generally, it is between 350 degrees and 400 degrees, as long as it is higher than the melting point of solder.
The najviša temperatura is općenito 480 degrees Celzijus, but it is općenito ok to set it to about 320~400 degrees. If it is higher, the tip of the soldering iron is easy to oksidaciju.
