3.5 Soldering
System
The CIG compact automatic soldering machine is fitted with two standard waves, the epm
hollow wave and the epm full wave. Both the solder waves are located in the same solder-
ing crucible. This ensures that both the waves have the same solder temperature. Each of
the two solder waves has its own pump system. The pumps are driven by tacho-DC mo-
tors, which are fitted with electronic stabilization against mains voltage fluctuations and me-
chanical load changes as well as with electronic short-circuit circuit breakers, and whose
power can be monitored and regulated independently of one another.
All the functions of the soldering system are regulated by microprocessors under closed-
loop control. The soldering temperature is freely programmable, under closed-loop control,
with digital display of the set and actual temperature. The large volume of the molten solder
and its intensive circulation through the solder pumps guarantee the smallest possible tem-
perature variation of the solder.
The soldering systems of the epm automatic soldering machine consist of the following
elements:
3.5.1 Solder
Bath
The soldering crucible consists of an insulated, double-walled stainless steel trough. There
is insulating material between the double walls. On one side of the crucible, there is a drain
cock for draining the fluid solder into a suitable tank. On the rear side of the crucible are the
electrical connections for:
•
Heating elements
•
Temperature sensor
•
Anti-explosion heaters / auxiliary heating
•
Solder level monitoring
•
Solder pump motors
The complete solder tank can be moved out of the automatic soldering machine by means
of a crank. The move-out path is limited. The bath is locked as soon as the solder tank
comes in contact with the stopper that is located at the end of the bath rail. In addition, a
move-out extension can be mounted. This extends the move-out path of the solder bath in
such a way that there is free access to all the elements
.
This construction makes optimum
service possible. After pushing in the bath, the inserted crank can be removed.
