Contact your local chemical supplier for recommended cleaning solvents applicable to the metals used in this product. Always use cleaning solvents in accordance with the manufacturer’s instructions.
WARNING
DO NOT allow nonmetal components (Seat, O-Rings, Dust Seal, Gaskets) to contact cleaning solvents! Cleaning solvents cause elastomeric and plastic parts to swell and stress crack. If these parts require cleaning, use a mild soap solution, followed by a thorough rinsing in water. Dry these parts completely before installing. REPLACE NONMETAL PARTS THAT HAVE COME IN CONTACT WITH OIL, GREASE OR ANY OTHER PETROLEUM-BASED SUBSTANCE! Petroleum-based substances become dangerously flammable in the presence of oxygen.

SECTION 4: TEST PROCEDURES
4.01 RECOMMENDED TOOLS & SUPPLIES FOR TEST PROCEDURES
Oil-free air or dry nitrogen supplies 2-3-101 Cutting tip Oxygen and acetylene gas supplies Small water tank
4.02 LEAK TEST THE GAS REGULATOR
1. Close the Cylinder Valves.
2. Turn the Pressure Adjusting Screws one turn counterclockwise. If the High Pressure Gauge reading drops, there is a leak in the Cylinder Valve, Inlet Fitting, or High Pressure Gauge. If the Low Pressure Gauge drops, there is a leak in the Torch Handle Valve, Hose, Hose Fitting, Outlet Fitting, or Low Pressure Gauge. If the High Pressure Gauge drops, and at the same time the Low Pressure Gauge rises, there is a leak in the Regulator Seat. Have a qualied repair technician repair the Regulator.
5/8”, 9/16”, 11/16”, and 1/2” Open-End Wrenches
1” Box-End Wrench
3. Use an approved leak detector solution to check for leaks.
4.03 LEAK TESTING THE TORCH
1. Connect the Torch to oil-free air or dry nitrogen supply lines with matching type regulator.
2. Insert a plugged cutting tip into Torch.
3. Pressurize the hoses to 50+/-5 PSIG.
4. Completely submerse the Torch in water.
5. Open the Valve Stem Assemblies. Check for leaks around all external connections. Observe the Valve Stem Assemblies. If bubbles
are escaping from around the Valve Stem Assembly packing, tighten the Packing Nut until it takes 1-1/4 to 2 in-Ibs of torque to adjust the Valve Stem Assembly knobs.
6. Close the Valve Stem Assembly knobs to a torque of 7-8 in-Ibs.
7. Remove the Plugged Cutting Tip from the torch. Observe the Torch Head. If bubbles appear at the Torch Head, one or both of the
Valve Stem Assemblies is leaking. Ream the Valve Seating surface using RT-33 reseating tool. Repeat steps 2 through 7.
4.04 FLAME TESTING THE TORCH
1. Remove the Torch from the water. Open the Valve Stem Assemblies for 10 seconds. Once all the water has been removed from the Torch, disconnect the hoses from the oil-free air or dry nitrogen supply. Attach them to oxygen and acetylene gas supplies.
2. Install a 2-3-101 cutting tip in the head. Tighten the Tip Nut to 10-15 ft-Ibs of torque.
3. Adjust the oxygen to deliver 40+/-5 PSIG. Adjust the acetylene to deliver 8+/-3 PSIG.
4. Open the Oxygen Valve and purge the oxygen line for ve seconds. Then, close the Oxygen Valve. Open the Fuel Valve and purge the fuel line for ve seconds.
5. Open the Fuel Valve Stem Assembly about 1/8 of a turn.
10˚
10˚
Ignite the gas with a spark lighter. Continue opening the Fuel Valve until the flame stops smoking.
6. Open the Oxygen Valve until a bright neutral flame appears.
7. Place the Tip on a re brick at approximately 10° from the vertical (see Figure). Depress the Cutting Oxygen Lever.
Rock the Torch from side to side for 5-8 seconds. The Torch will “pop” during this operation.
Fire Brick
!
WARNING
If you experience a backfire or backflash (flame disappears suddenly and/or a hissing sound IS heard when the flame is burning inside the torch), IMMEDIATELY turn OFF first the Oxygen Valve and then the Fuel Valve. Allow the Torch to cool before reusing it. If the trouble reoccurs, disassemble the Torch. Replace any damaged parts.
8. After testing is completed, release the Cutting Oxygen Lever. Close the Oxygen Valve and the Fuel Valve.
9. Close the Cylinder Valve or Gas Supply.
10. Open the Oxygen Valve. Release the oxygen from the system. Once all the oxygen is released from the system, close the Oxygen Valve.
11. Open the Fuel Valve. Release the fuel gas from the system. Once all the fuel gas is released from the system, close the Fuel Valve.
12. Remove the Hoses from the Torch.
