3.03 Post Installation
The installation should allow for integration to the controlling
device and air input supply lines. If these items are subject
to welding spatter or other detrimental surroundings, they
should be protected by adequate means.
After the installation is complete, the mister should be set in
the following manner:
STEP 1 Fill reservoir with anti-spatter compound. A minimum
of 3 oz (87ml) 3/4” must be in the reservoir.
STEP 2 Air supply needs to be at a constant regulated
pressure between 80-120 PSI.
STEP 3 Set nozzle cap in accordance with amount of anti-
spatter compound required.
STEP 4 Monitor the welding process to verify the proper
amount of anti-spatter being applied to prevent weld
slag buildup on the nozzle, diffuser and contact tip
area.
These steps will provide sufficient anti-spatter compound
for most applications. To increase the amount of anti-spatter
applied, turn nozzle cap counter-clockwise or increase the
amount of time the anti-spatter sprayer is on.
