Other Components That May Be Required For Mechanically
Operated Welders (continued)
Filter-regulator-lubricator (frl) assembly (If furnished—See enclosed
manual KSL-208)
The filter cleans air that goes to the solenoid air valve (and air cylinder, if furnished). The regulator and gauge are used
to adjust air pressure. The lubricator keeps the solenoid air valve or the air cylinder (if required) properly lubricated.
The filter-regulator unit with one threaded pipe plug, lubricator, gauge, mounting bracket, and a connector or nipple
are shipped together.

Lubricator Assembly
Part No. RCL-043
The air filter must be kept clean at all times. Never operate the machine unless the air filter is clean.
The lubricator must not be filled while under pressure.
Regulate the air pressure high enough to develop sufficient pull (or push) to operate the welder mechanically.
Never apply more than 145 PSI.
Bring shop air supply to the welder. Connect the air supply at the threaded opening, indicated as In by the
direction arrow on the filter-regulator. Maintain minimum
Important—Blow air line clear of all dirt, scale, etc., before connecting filter. Drain water out of
filter bowl when filled. If bowl fills with water in a short period of time, install a larger filter in
your main air supply line leading to the welder.
It is recommended that a manual shut-off valve be installed in the main line ahead of the
filter-regulator-lubricator assembly and close to the welder for convenience and lockout.

SECTION 2—INSTALLATION OF COMPONENTS
Unpack the filter-regulator unit and install the connector between the filter-regulator-
lubricator (see arrow for air flow direction). Tighten this assembly and position the two
units with both bowls in alignment. Be sure to check air flow direction and the location
of the valve to avoid excessive piping.
Choose an appropriate location on the machine for mounting this assembly. If possible,
it should be accessible from floor level.
Install the pressure gauge in the threaded port opposite the mounting surface and plug
the unused port. Attach the mounting bracket to the machine and then mount the FRL
assembly using the lock nut supplied.
The length of the air line run is not critical; however, the port and pipe sizes should be
maintained.
Fill the lubricator with a good quality lubricant (see OEM's specifications) to the level
indicated by the maximum fill line on the transparent reservoir. Do not overfill. When
the machine is cycled, the lubricator drip rate may be adjusted according to the
instruction manual. Please check the machine owner's manual for proper specifications
for oil, if required. Some clutch and brake assemblies do not require lubrication.
