5. INSTRUCTIONS OF USE
EN
5.1. Choose the appropriate lance to the thickness to be welded (see table 7); follow the
PT
CONNECTION instructions (Section 2) and the use of the CS-300 handle.
5.2. The CS-300 torch works on the INJECTOR principle and the following method of lighting
EN
& closing should therefore be adopted.
5.3. Check that both oxygen & gas valves of the shank as well as the regulator adjusting
valves are closed. SLOWLY open the gas cylinder valves.
5.4. Set on the oxygen & gas regulators the recommended working pressure for each
thickness (see table 8).
5.5. Open one turn, first the oxygen valve on the shank & wait that oxygen flows out; it will
produce a noise in the flexible hose. Follow same procedure for the fuel gas valve of the
torch.
5.6. Light the flame preferably with special gas lighter.
5.7. Adjust with both valves on the shank until obtaining the suitable heating flame. Watch
the flame variation pushing on the oxy-cutting lever, while adjusting with the valves if
necessary. Check on regulators that preset pressures remain the same. On the
contrary, adjust till the recommended values are reached.
5.8. Adjust the torch by cutting with pre-heating flame on the side of the sheet metal till
reaching the suitable heat. Fully open the valve for cutting oxygen & push on at
suitable speed to oxy-cut.
5.9. To extinguish the flame, first close the gas valve & then the oxygen one on the shank.
6. MAINTENANCE
6.1. Protect the torch from damage (check visually at regular intervals).
6.2. Clean the torch at regular intervals to avoid presence of grease or dirtiness. When
necessary, clean the holes of the cutting nozzles with the cleaning needles supplied (art
Cod. 2305203.
6.3. Check that flexible hoses are in good condition & remove parts that are damaged.
