OPERATING INSTRUCTIONS
Connecting the torch
Connect the torch to the cylinder regulators
or with a central gas supply to the supply
points with the approved hose. Secure the
connection with hose clamps. If leakage is
suspected, check using soapy water.
Lighting and regulating the torches
(using the valves on the torch)
A) Welding, brazing, heating, etc.
1. Attach an appropriate welding or heating
mixer into the shank of the torch. Check
that the sealing O-Ring at the end of the
mixer is intact.
2. Close both valves (4 and 5) on the shank.
3. If regulator is tted with a needle
valve this should be opened. Using the
regulator’s pressure adjusting screw set
to the recommended working pressure.
The same applies to supply points if a gas
pipeline is used.
4. Open the oxygen valve (4) on the shank
and allow the gas to purge the hoses
for a short time. Long hoses and small
welding nozzles require a longer purge
time. Maintain a small gas ow.
5. Open the torch fuel gas valve (5) on the
shank and allow the gas to ow for a
short time. Purge as above.
6. Light the torch.
7. Regulate the size and type of ame with
the valves (4 and 5) on the shank. The
torch is now ready for use.
B) Cutting
1. Attach the cutting attachment to the
shank. Provide with a suitable cutting
nozzle.
2. Open the oxygen valve (4) completely
and close the fuel gas valve (5). Close
the cutting attachment’s heating oxygen
valve (8)
3. With the help of the adjusting screw
on the regulator set the recommended
working pressure.
4. Open the heating oxygen valve (8) and
allow the gas to purge the hose for a
short time. Long hoses and/or small
cutting nozzles require a longer purge
time. Maintain a small gas ow.
5. Open the torch fuel gas valve on the
shank (5) and allow the gas (acetylene
or propane) to ow. Purge as above.
6. Light the ame.
7. Open the cutting oxygen valve by
pressing down on the lever (9). Adjust
to correct oxygen pressure with the
adjusting screw on the regulator or
supply point.
8. With the cutting oxygen owing, adjust
the heating ames using the fuel gas
valve (5) on the shank and the cutting
attachment’s heating oxygen valve (8).
The torch is now ready for use.
Extinquishing the ame
A) Welding, brazing, heating, etc.
First close the fuel gas valve (5) on the shank
and then the oxygen valve (4).
B) Cutting
Release the cutting oxygen lever (9). Close
the fuel gas valve (5) on the shank and then
the cutting attachment’s heating oxygen
valve (8).
MAINTENANCE
Keep the torch clean. Do not grease any parts.
Oil or grase can be explosive when in contact
with oxygen.
When necessary clean the holes of the
welding and cutting nozzles with appropriate
cleaning needles. Push these carefully in and
out without twisting. Spiral drills steel wires,
etc. scratch and spoil the nozzle channels.
If the outlet end of the welding or cutting
nozzle is damaged, it may be repaired by
polishing perpendicularly with a ne emery
cloth laid on a at surface. Obtain help from a
sevice engineer if repairs are necessary.
