Theory of Operation
Gun Triggered (Fluid Spraying)
Purge rod (31) moves back, opening impingement ports
(IP). Components A and B combine in mix module (39).
Fluid sprays from CeramTip (40).
Cleanoff air flows whether gun is triggered or detrig-
gered. See page 13 to adjust.
Gun Detriggered (Mechanical Purging)
Purge rod (31) moves forward, closing impingement
ports (IP) and shutting off fluid flow. Rod pushes through
mix module (39) and bottoms on CeramTip (40), forcing
out excess fluid and restoring proper orifice diameter.
Cleanoff air flows whether gun is triggered or detrig-
gered. See page 13 to adjust.
