Application
The operation is a little bit easy, and the heating time is somewhat short too, so
when using the welding machine , probably you won’t be so careful. But here we
have to warn you seriously. In order to guarantee the user’s safety and prevent the
welding machine from being damaged, please obey the safety hints and the
warning signs in this operation instructions, and obey the relating regulations.
Safety regulations
•the welding machine is only allowed to weld and unsolder the electrics and the
electrons
in the printing electrical circuit and the models; tin the circuitry and the
lead; connects the lead
•The welding machine is absolutely prohibited to be used to heat the liquid(water,
electrolyte and ?) or heat the plastics parts(it will form poisonous air and cause
fires).
•components.
Tin the new soldering mouth when using the machine at first time. To do this,
switch on the welding machine, then thaw a little soldering tin into a thin film
which can be affixed on the welding mouth when temperature reaches about
200
0
C.
The key to ensure the quality of welding point is the proper welding
temperature. The welding temperature of electric components is from 300
0
C to
380
0
C. Too low temperature will lead to cold welding point while too high
temperature will result in drop of the welding preparation and rupture of the
jointing slot. Moreover too high temperature will also possibly lead to damage of
circuitry (the plating layer of the lead) and components. Before welding, clean the
soldering mouth directly with the sponge so as to clean away the welding
preparation hangover which has not completely boiled away, the oxides and other
impurities and this can prevent them from dropping to the welding point. After
welding, the welding mouth has to be cleaned again and has to be filmed a little tin
before the electric iron is put again on the frame. It is very important to film the
welding mouth with solder, otherwise the welding mouth will be passivated after a
period of time and cannot absorb the welding preparation any more.
1. Heat to working temperature (the welding temperature regulated on the weld
machine), then put the welding mouth which is cleaned and equably filmed with
tin and the welding rod together on the welding point. The welding preparation
will melt first to clean the surface of the metal which needs welding. Then the
welding tin melts so as to create relating conductive connections. The welding of
electric components costs not more than 2 minutes.
The well-welded jointing point looks slick and lustrous after cooling. While
the welding point with bad quality and many mistakes looks lusterless, uneven and
easy to crack. The causes leading to such result are as following: the improper
solder is used or the welding temperature is regulated too high. Another familiar
used last time and the higher line will display current temperature of the electric
