Pouring solder in again
WARNING
Risk of death or severe injuries due to hot machine!
a) When manually topping up solder, liquid metal can splash out of the solder pot!
Solder manual top-up should always be carried out by trained personnel!
b) Wear safety shoes, face protection, protective gloves, safety apron!
ü Pour in the skimmed solder again until the desired solder level is reached.
ü The skimmed solder is cooled and completely solidified.
a) Very slowly place the solidified solder pieces into the solder bath one after the
other.
ð Risk of accident! Touching the hot solder surface is also forbidden with
protective gloves!
ð Always place only a small part of solid solder into the solder bath. Only
place the next small part into the bath when the previous part has com-
pletely melted.
ð Repeat the process until the desired solder level is reached.
ð The process has now been completed.

Fig.158: Assemble the nozzle plate. Always hold bolted removing tools by the upper toggle (A)!
ü To assemble the nozzle plate:
ü Both removing tools are mounted on the nozzle plate and locked.
ü The top edge of the pressure chamber is completely covered with solder and
free from oxides and solder dross.
ü The bayonet catches were aligned in such a way that the slots of the screws
run parallel to the edges of the nozzle plate.
a) Risk of accident! Check the locks for tightness again!
b) Lift the nozzle plate holding it with both hands by the upper toggles (A).
ð Risk of accident! Always hold bolted removing tools by the upper toggle
(A)!
c) Place the nozzle plate very slowly on the solder surface and position it carefully
using the coding keys (X).
ð If the machine has the [Setup control] option:
d) Insert the RFID chips into the chip reader.

e) Move the screws of the bayonet catches one after the other with a suitable
tool. While doing so, press the nozzle plate slightly downwards.
ð As a result, the nozzle plate is completely lowered onto the pressure cham-
ber.
f) Turn the rotary switch (D) on the control console clockwise.
ð This will turn on the solder wave. Do not operate the pump unnecessarily
long without nitrogen gassing. Otherwise, an unnecessarily large amount
of solder dross is generated.
g) Wait for approximately 10 minutes until the nozzle plate has warmed up and
the solder has reached its target temperature again.
h) Remove the removing tools.
i) Secure the nozzle plate using the socket spanner as shown.
j) When fixing the nozzle plate, always start at zero point (C) and proceed accord-
ing to the numbering shown.
k) Clean all inlet holes with a circular brush.
l) Visual inspection of the solder wave height:
ð Nozzles must be uniformly filled with solder; the wave height must be the
same for each nozzle.
ð The process has now been completed.
