5. OPERATION
5.1. CONNECTING THE SHANK
• Connect the shank to the cylinder regulators or with a central gas supply to
the supply points with approved hoses. Secure the connection with hose
clamps.
• Check the gas tightness by soapy water or detection fl uid.
5.2. LIGHTNING AND REGULATING OF THE WELDING, HEATING
AND CUTTING ATTACHMENTS
5.2.1. WELDING, BRAZING AND HEATING
NOTE: This torch operates on the injector principle. The instructions below
should therefore be followed carefully.
1. Check the sealing washer (7) on the inlet connection of the attachment for
damage.
2. Fit an appropriate welding or heating attachment with a nozzle into the
shank.
3. Close the oxygen valve (4) and the fuel-gas valve (3).
4. Set recommended working pressures by means of the adjusting screw on
the regulators.
5. Purge the hose briefl y with gas by opening the oxygen valve (4). Long hos-
es and/or small cutting nozzles require somewhat longer purges. Close the
oxygen valve (4).
6. Open the fuel-gas valve (3) and purge as above. Maintain suffi cient fuel-gas
fl ow for proper purging. Close the fuel-gas valve (3).
7. Open valve for oxygen (4) a little and than for the fuel-gas valve (3) a little bit
more.
8. Light the gas mixture in front of the welding or heating nozzle.
9. The heating fl ame can be adjusted by means of the oxygen valve (4) and the
fuel-gas valve (3).
10. The device is now ready for use.

1. Check the sealing washer (7) on the inlet connection of the attachment for
damage.
2. Fit a cutting attachment into the shank.
3. Fit an appropriate cutting nozzle
4. Close the oxygen valve (4) and the fuel-gas valve (3). Release the lever or
close the cutting oxygen valve (14).
5. Fully open valve for heating oxygen on the cutting attachment (13).
6. Set recommended working pressures by means of the adjusting screw on
the regulators.
7. Purge the hose briefl y with gas by opening the oxygen valve (4). Long
hoses and/or small cutting nozzles require somewhat longer purges. Close
the oxygen valve (4) and the heating oxygen valve (13).
