Problem Solutions
Excessive smoking from tank and
gun
1. Adjust the tank temperature controller according to
section 5.3 of this manual. Inadequate tank
temperature can affect the performance of your hot
melt system. If the tank has reached an
overtemperature condition, try turning the controller
down. A failure of the solid state relay (closed
position) can cause the tank to reach over
temperature. Check the relay’s continuity – failure of
the relay is rare. If problem persists, replace the
faulty component (controller or relay). On units with
Standby, make sure Standby switch is disengaged
and in the Run position.
2. Adjust the supply hose temperature controller
according to section 5.3 in this manual. Inadequate
supply hose heat can affect the performance of your
hot melt system. If problem persists, see Hose
Controller Replacement, section 8.2, and section 9
for hose temperature controller kits.
3. Adhesive formulations tend to be a factor in each
previously listed problems. Refer to Startup
Instructions (section 5.2), for cautionary notes.
System should be purged if formulation is incorrect.
