INSTALLATION AND OPERATION
3.01 Starting Installation
The QRM-3 Anti-Spatter Sprayer was primarily designed
to be mounted at the right side of the Tweco ® Robotics
QRC TM -2000 Nozzle Cleaning Station. It can also be
mounted in a variety of other convenient locations. For
best results, the sprayer should be installed within the weld
cell at a convenient location where the welding torch can
easily access. The QRC TM -2000 Nozzle Cleaning Station
has all the necessary mounting holes needed to install the
QRM-3 anti-spatter sprayer.
1. Attach the mounting block (#5) to the right side of the
QRC-2000 using two (2) 1/4-20 x 1.25” screws (#1)
(use Loctite).
2. Assemble the mister/valve sub-assembly (#8) onto
the mounting block with two (2) No.6-32x1.5” screws
(#7) (use Loctite).
3. Install 10-32 x1/2 screw (#10) with lock washer into
mister/valve sub assembly.
4. Screw the air fitting (#4) into the air intake port on the
QRC TM -2000.
5. Press one end of the 1/4” tubing (#9) into the air
fitting (#4) and the other end in to the bottom of the
sprayer/valve sub-assembly (#8).
6. Remove the red plug in the side of the sprayer/valve
sub-assembly. Place the cover (#6) over the sub-
assembly as shown and screw the exhaust port (#3)
into the hole on the side of the cover. Attach the cover
with (2) 10-32 x 11⁄2” counter-sunk screws. (#11).
