The 3M™ Scotch-Weld™ Hot Melt Applicator PG II
LT is designed to be a simple, reliable tool for
dispensing 3M™ Scotch-Weld™ Hot Melt LM
Adhesive Sticks.
It is self-contained and hand held, designed for multi-
station or intermittent manual adhesive application.
The 3M Scotch-Weld Hot Melt Applicator PG II LT
uses electric heat to melt the adhesive, and air
pressure to deliver the adhesive. Adhesive
temperature is automatically maintained by a fixed
thermostat on the heat block. The system is further
protected by a thermal cutout (TCO), which acts as a
thermal fuse.
Please take time to properly fill out and return
your 3M Scotch-Weld Hot Melt Applicator PG II
LT Warranty Card.

Use 3M Scotch-Weld Hot Melt LM Adhesives only.
Use of other adhesives may damage the applicator or
result in hazardous conditions.
READ INSTRUCTIONS THOROUGHLY BEFORE OPERATING OR PERFORMING ANY
MAINTENANCE ON 3M™ SCOTCH-WELD™ HOT MELT APPLICATOR PG II LT.

Important
When trigger (1) is pulled, the variable regulator (2)
allows air pressure into rear of the Speedloader stick
feed (3). Air pushes the piston (4), which advances
adhesive stick through applicator. As adhesive
advances, it passes through hard plastic insulating
sleeve (5) which acts as thermal barrier to keep
molten adhesive and heat in forward portion of the
applicator. The rest of the applicator stays cool.
As adhesive advances into the heat block, it is melted
and liquefied. With pressure from the solid adhesive
sticks and the piston, the liquid adhesive is forced out
of the applicator through the nozzle tip (6). When the
trigger is released, air pressure is released from the
rear of the loading chamber. Pressure on the molten
adhesive in the front of the applicator is then also
relieved. Spring tension in the nozzle valve retracts
the valve, neatly cutting off the adhesive flow.
The delivery rate of molten adhesive for the 3M
Scotch-Weld Hot Melt Applicator PG II LT is
approximately six pounds per hour with 3M™
Scotch-Weld™ Hot Melt Adhesive 3762-LM utilizing
the standard tip 9921. Adhesive flow rates will vary
with the different 3M adhesives in the line and the
nozzle tip you choose.
