Flow Control
Flow control of adhesive with your new 3M™ Hot Melt Applicator
PG II is easy. An operator familiar with the control devices should
be able to adjust the applicator for desired flow. To adjust adhesive
flow, a combination of these control methods can be used.
The four control devices are:
1. Speed of 3M Hot Melt Applicator PG II movement.
2. The trigger.
3. The nozzle tip.
4. Air pressure.
The trigger of the applicator is uniquely designed to allow for
variable control. By pulling the trigger slowly to the rear, you can
observe the start of adhesive flow. As you continue to pull the
trigger rearward, increasing amounts of adhesive are dispensed.
Two nozzle tips were supplied with your 3M Hot Melt Applicator
PG II: a .093" (9921) fluted tip and a .072" (9946) brass extension
tip. The applicator was shipped with the .093" (9921) tip on the
applicator. This tip will provide maximum flow for all 3M™ Hot
Melt Adhesives except 3746 and 3783. The brass extension tip
(9946) will allow for maximum control of all the adhesives and
substantially eliminate initial surge. This is accomplished at a
decrease in flow rate. Speed of movement is the preferred means
to control flow. In the event that this is inappropriate for your
operation, additional accessory tips are available.
NOTE: DO NOT REDUCE AIR PRESSURE BELOW 40 PSI (275 kPa).
If low adhesive flow occurs when operating at reduced air
pressure, return to maximum (80 psi) (551 kPa) and run at least
one stick of adhesive through the applicator and then return to
the lower pressure.
