MAINTENANCE INSTRUCTIONS
For all repairs other than those covered below, send the appara-
tus to the nearest ESAB distributor or to ESAB Remanufacturing
Center, 411 S. Ebenezer Road, Florence, SC 29501. Improperly
repaired apparatus is hazardous.
Preheat Valves: Leakage around either throttle valve can usually
be corrected by tightening packing nut slightly. If this does not
stop the leakage, replace the valve assembly.
If either preheat valve fails to shut off completely, remove the valve
assembly from the torch. With clean cloth, wipe the ball in the end
of the stem. Then reinsert valve assembly and tighten it several
times with maximum force. If this does not eliminate leakage, try a
new valve assembly. If then the valve does not shut off completely,
send the torch to a repair station for reseating of the body.
After installing a new throttle valve assembly, tighten the packing
nut until the valve can be turned only with great difficulty, and set
the unit aside, for three or four hours at least, to set the packing.
Then back off the packing nut until the valve turns readily.
Cutting Valve: If leakage is detected between the cutting valve
stem cap and the valve, or if the cutting valve fails to shut off
completely, remove cutting valve lever and then unscrew the
valve assembly (08M05), You may either replace the entire valve
assembly or disassemble the valve assembly to replace valve
stem (19216), seat (19215), and O-ring (14K11). If the latter,
unscrew the valve stem from the cap (824). Using the new valve
stem, seat, and O-ring, reassemble the valve as follows:
1. Place the new O-ring and retaining washer (10K23) in
the valve nut (19217).
2. Insert the valve spring (23K07) behind the retaining
washer and hold in place firmly while inserting new
seat, and then new valve stem through the valve nut
and O-ring.
3. Screw the valve stem into the valve stem cap firmly.
4. Replace O-ring (14K07) about the seat of the valve
nut if O-ring appears distorted.
5. Screw the entire assembly into the torch body and
tighten firmly with a wrench. Reassemble the cutting
valve lever to the torch body.
Cleaning Cutting Nozzles: Cutting nozzle orifices should be
cleaned by hand using OXWELD tip cleaners, whenever a flame
distortion is noticed. Maintaining clean orifices is highly recom-
mended for reducing any incidence of flashbacks. If you do not
have tip cleaners, twist drills of the correct sizes (see table on pg.
4) may be used. Insert the drill carefully, and push it back and forth.
DO NOT TWIST THE DRILL.
To clean the preheat slots on internal nozzles, remove the external
sleeve and use a soft bristled brush (750F99).
