Temperature regulating
2 Put the power supply switch to location 1 and the weld machine is being connected.
At that time the lower line on the screen will display a set temperature
2 (up+ switch) or decrease (down- switch) by 1
0
C every time you press the switch
momently. If you press the switch without move, regulating will go on
3 by10
0
C every grade till the demanded temperature is displayed.
4 It is also can push(200•, 300•, 400•)button to set the value directly.
5 When the welding temperature is regulated to a wanted number, the factual working
temperature will approach the set temperature gradually.
Instructions:
. When the weld machine is turned off, the regulated temperature will be kept
automatically. And when you turn on the machine next time, this set temperature will
be displayed automatically.
. Once any malfunction happens for example the temperature sensor is damaged, or
the connecting lead between the electric iron and the weld machine is disconnected,
the display will show malfunction. Further, the piezoelectricity sensor inside will give
out sound of alarm. In that situation, shut down the machine immediately, s witch off
the power supply and look up possible cause resulting in malfunction.
Operation:
To make welding work perfect, you have to use the proper welding rod and operate the
weld machine accurately. Electric welding rod with colophony is advised to use. Any
welding preparation with halogen is forbidden. The welding preparation on the rod can
clear away the impurities and oxides on the welding point that will do harm to welding and
prevent new oxides from being created in the course of welding. In practice, alloy solder L-
SN60PbCu2•German Industry Standard 8516•with 60% tin•60/40 solder• is mostly
used. This solder has many welding rod standards and 1mm welding rod is advised to use
in electric
•only the operation safety of the weld machine is guaranteed, can we use the weld
machine. In the following circumstances, the operation safety may not available:
•If there are damages which can be seen with our eyes, (for example, insulation has
problems, the crust crazes );
•the weld machine can not operate

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
