OPERATION
5.1.CONNECTING THE TORCH
• Connect the torch 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 fluid.
5.2.LIGHTNING AND REGULATING OF THE CUTTING TORCH
NOTE: This torch operates on the nozzle-mixing principle. The instructions below
should therefore be followed carefully.
1. Fit an appropriate cutting nozzle (see cutting table - Appendix 1).
2. Close the heating-oxygen valve (5) and the fuel-gas valve (4). If the lever for
cutting oxygen is locked in open position, release it by loosening the locking
button (7).
3. Set recommended working pressures by means of the adjusting screw on the
regulators.
4. Purge the hose briefly with gas by opening the heating-oxygen valve (5). Long
hoses and/or small cutting nozzles require somewhat longer purges.
5.
Close the heating-oxygen valve (5).
6. Open the fuel-gas valve (4) and purge as above. Maintain sufficient fuel-gas flow
for proper purging.
7. Close the fuel-gas valve (4).
8. Open the heating-oxygen valve (5) and open little bit more valve for fuel gas (4).
9.
Light the flame in front of the nozzle .
10. Open the cutting-oxygen by depressing the lever (6). Lock the lever in open
position by pushing the button (7). Adjust the oxygen pressure by means of the
adjusting screw on the regulator or the supply point.
11. Once the cutting oxygen is flowing, the heating flames can be adjusted by
means of the heating-oxygen valve (5) and the fuel-gas valve (4).
12.
The torch can now be used for cutting.
5.3. EXTINGUISHING THE FLAME
1.
Release the lever of the valve (6) for the cutting oxygen.
2. Slowly close the valve for fuel gas (4) and after that valve for heating oxygen (5).
