8.11.9 DIP soldering module (multiwave) with induction pump: Solder pot
replacement (optional)
The solder pot replacement is carried out with hot, but solidified solder. Therefore,
the following safety instructions must be strictly followed:
DANGER
Severe or fatal injury from hot machine!
The entire machine is hot during operation and contains liquid metal!
a) Service on the hot machine may only be carried out by specially trained staff,
qualified for this type of work! For these types of work, a company internal oper-
ating procedure for protective clothing is to be issued!
b) You should always take into account the possibility for metal to spray out!
c) Special care is required when refilling the pot and working on the pot!
DANGER
Risk of death or serious injury due to liquid metal; danger of material damage!
When moving the hot solder pot, liquid metal may leak!
ü Before replacing the DIP solder pot:
ü The DIP solder pot can only be replaced by specifically trained personnel!
ü Shut off the work area with a red and white safety chain and a warning sign!
ü Remove any tripping areas.
ü Move both solder pots only when the solder has solidified completely!
a) Always seek the help of second worker to replace the DIP solder pot!
b) To transport the solder pot, always use the specific replacement rack and the spe-
cific lifting cart!
c) Under no circumstances can the replacement rack and the lifting cart be modified
or tampered with!
d) Always move the solder pot carefully when transporting it!
DANGER
Risk of death or serious injury due to liquid metal; danger of material damage!
After replacing the solder alloy, the correct value of the solder melting temperature
must always be set in the machine software!
ü After replacing the solder alloy:
ü Solder alloy can only be replaced by qualified personnel, specifically trained for
this job!
a) After replacing the solder alloy, the correct value of the melting temperature of
the solder alloy used must always be set in the machine software!

NOTE
Use suitable protective equipment!
When performing any work on a hot pot, protective clothing must be worn:
a) Safety shoes
b) Face protection
c) Heat resistant gloves
d) Heat resistant apron
WARNING
Death or severe injuries are possible with extended soldering module!
ü If the soldering module is on the replacement rack while it is hot:
a) Shut off the work area with a red and white safety chain and a warning sign.
b) Remove possible tripping areas!
Replacing the DIP solder pot
The procedure for replacing the DIP solder pot takes about 30 minutes (if the DIP
solder pot has cooled down to the set temperature and if the DIP solder pot has
been heated in the heating station and has reached the set temperature). The pro-
cedure involves the following seven steps:
– Preparation for solder pot replacement
– Mounting the traction aid on the machine
– Operating the lifting cart with the replacement rack
– Connecting the cold solder pot to the (optional) heating station and preheating
it
– Removing the cooled DIP solder pot from the machine
– Inserting the (optionally pre-heated) DIP solder pot into the machine
– Replacing solder in the automatic solder feeder (optional)
– Completing the DIP solder pot replacement process

8.11.9.1 Preparation for solder pot replacement
NOTE
Let the solder cool off before replacing the DIP solder pot
Let the solder cool off before replacing the DIP solder pot. To do so, it must be solidi-
fied. A safety switch prevents the extraction of the DIP solder pot in case the solder is
still too fluid or too hot.
ü Cool down the DIP solder pot to the necessary set temperature.
ü The machine is in the [Maintenance mode].
a) Open the start dialog.
b) Open the input dialog for the DIP soldering module.
c) Click on the button
.
ð The DIP soldering module is moved to the [Service] position.
d) Now, if necessary, remove the nozzle plate of the DIP soldering module. For
more information, please also read the relevant chapter DIP soldering module
(multiwave) with induction pump: Clean the solder pot [}386].
ð Use the support provided.
ð After removing the nozzle plate, and before replacing the solder pot, insert
the solder pot into the machine, as described.
e) In the [Solder pot], click on the button
to switch off the heating.
ð The button is then displayed in grey.
ð The heating is switched off, and the solder will slowly cool down.
f) To avoid any unnecessary delay in the solder pot replacement procedure,
check whether the cold solder pot is already connected to the optional heating
station, and whether it is preheated so that it can reach the required set tem-
perature. For more information, please also read the relevant chapter Connect-
ing the cold solder pot to the (optional) heating station and preheating it
[}425].
g) If the machine has the [Hold Down] option, remove the [Hold Down].
h) If the machine has the [Solderbar feeder] option, remove the [Solderbar
feeder] and place it in the storage compartment on the corresponding DIP
solder pot.
i) Wait until the solder of the DIP solder pot has cooled down to the required set
temperature.
ð The process has now been completed.
