7. Insert the cutting tip into the cutting attachment and tighten securely with a wrench.
8. Open the oxygen control valve on the torch handle completely.
9. Open the oxygen control valve on the cutting attachment and depress the oxygen cutting
lever. Adjust the oxygen regulator to a delivery pressure suitable for the tip type and
size. See Cutting Tip Chart in Section 6.
10. Release the oxygen cutting lever and close the oxygen control valve on the cutting
attachment.
11. Open the fuel control valve on the handle completely.
12. Open the fuel control valve on the cutting attachment. Adjust the fuel gas regulator to a
delivery pressure suitable for the tip type and size. See Cutting Tip Chart in Section 6.
13. Close the fuel control valve.
14. Check for leaks. See Section 5.3
15. Light the torch. See Section 5.4
5.3 Check for Leaks
Follow the below procedures before each use of the torch.
1. Close the cylinder valves.
2. Turn the pressure adjusting screw counterclockwise by one turn. Observe the high
pressure gauge. If there is a drop in pressure, a leak exists in the cylinder valve, inlet
fitting or high pressure gauge. Observe the low pressure gauge. If there is a drop in
pressure, a leak exists in the torch handle valve, hose, hose fitting, outlet fitting or low
pressure gauge. If both gauges drop in pressure, there is a leak in the regulator. DO
NOT use if a leak exists in the regulator. Replace or have a qualified repair technician fix
the regulator.
3. Use an approved leak detector solution to determine where the leak exists.
5.4 Lighting the Torch
For the Welding Procedure, follow steps 1 through 7. For the Cutting Procedure follow steps 1
through 11. See Figure 4
1. Wear appropriate safety gear.
2. Ensure system has been appropriately purged. See Section 4.3
3. Point the torch tip away from people, cylinders and flammable materials. Open the fuel
gas valve about 1/8 turn. Ignite the gas with a striker. The resulting flame is a “Pure
Acetylene Flame.”
4. Adjust the fuel valve until all smoke and soot are removed from the flame. If smoke
persists, adjust the pressure on the acetylene regulator. DO NOT exceed 15 psig on the
acetylene regulator.
