Test Procedures for Victor Cutting Torches

Important Notes

  1. Test with oil-free air or dry nitrogen only.
  2. Always wear eye protection while testing.
  1. Attach the hoses to the cutting torch.

  2. Figure 1Install a plugged cutting tip in the head. Tighten the tip nut to 15-20 ft. lbs. of torque assuring the test gas cannot pass from the fuel side to the oxygen side in the torch head.

  3. Close the control valves and pressurize the oxygen and fuel side of the torch to the appropriate pressure.
  1. 80 PSIG - HCl500C
  2. 45 PSIG - All other torches.
  1. Submerse the torch in water.

  2. Open the cutting oxygen and fuel control valves.
  1. Check around all connections for leaks.
  2. There should be zero leakage past the packing in the valve stem assembly in five (5) seconds.
  1. Close the cutting oxygen and fuel control valves. Use 7 to 8 in. lbs. of torque.

  2. Remove the cutting torch head plug. There should be zero leakage through the control valves in five (5) seconds. If there is a leak, bubbles will come through the head.

  3. Release the air pressure from both sides of the torch.

  4. Figure 2Install a plugged cutting tip in the head with the small seating surface removed. Testing gas must be permitted to pass from the fuel side to the oxygen side in the head.

  5. Open the fuel control valve.

  6. Remove the fuel hose from the pressure source.

  7. Apply 2 PSIG to the oxygen valve.

  8. Open the oxygen control valve.  Hold the loose end of the hose under water for ten seconds.  If the check valve leaks, bubbles will come from the open end of the hose.

  9. Turn off the pressure to the oxygen side.

  10. Remove the oxygen hose from the regulator.

  11. Attach the fuel hose to the pressure source.

  12. Apply 2 PSIG to the fuel valve.

  13. With the oxygen control valve still open, hold the oxygen lever down.  Hold the loose end of the hose under water for ten (10) seconds.  If the check valve leaks, bubbles will come from the open end of the hose.

  14. Release the pressure from the fuel side.

  15. Close both control valves.

  16. Remove the cutting torch head plug or tip blank.

  17. Attach the torch handle to oxygen and fuel gas sources.

  18. Install a tip in the head and tighten the tip nut to 15-20 ft. lbs. of torque.

  19. Light the tip and adjust to a neutral flame.

  20. Open the cutting oxygen valve.  Some adjustment will be necessary to maintain the neutral flame.
    Figure 3
  21. Position the tip 10 degrees from vertical and rotate it against a fire brick for 5-8 seconds.  The torch should make a popping sound.  If the flame goes out and the torch makes a whistling sound immediately turn off the oxygen then the fuel.  This is caused by a back-burn or flashback.  If this occurs, repeat steps 24-26.  If this occurs more than twice, disassemble and examine the torch and replace any damaged parts.

  22. Turn off the oxygen and acetylene gas supply.

  23. Bleed the pressure from the torch and hoses.

  24. Close the control valves.
