what it requires.

3) Turn on and turn off the power switch of the welding.
4) The diode plug(180 )with 5 conjunctions is used to combine the hot irons

 

and the welding machine which are under the control of the sensor.

5) The

 

electric soldering irons frame, installed with protective equipment through 

toughing and sponge trays which can be drew out.

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
