Figure 29: Vacuum Pick-Up System
Interchangeable vacuum tips (1), which may
or may not have a silicone vacuum cup (2),
are screwed into the vacuum stem (3) with
#10-32 threads. The vacuum transfer tube
(4) pipes the vacuum from the tubing (5) to
through the lower heater housing (6) to the
stem. A vacuum generator (Item 2, Fig. 30),
generates the vacuum pressure. A leak
anywhere in this system may cause weak
vacuum at the tip.
