Checking and setting the nitrogen flow
ü To check the nitrogen flow for monitoring the solder level:
a) For each soldering module, a flow meter is available. The flowmeters (2) are
located above the soldering modules on the right side, behind the cover plate.
b) On the adjustment knob (1), set a value of at least 0.15 l/min.
c) Repeat the procedure with all available flow meters.
ð The process has now been completed.
