8. Proper cylinder care. Secure cylinders to a cart, wall, or post, to prevent them
from falling. All cylinders should be used and stored in an upright position.
Never drop or strike a cylinder. Do not use cylinders that have been dented.
Cylinder caps should be used when moving or storing cylinders. Empty cylinders
should be kept in specified areas and clearly marked “empty”.
9. never use oil or grease on any inlet connector, outlet connector, or cylinder
valves.
10. Always use reverse-flow check valves on the torch and regulator. This
greatly reduces the possibility of mixing gases in the regulator or hose.
11. Working pressure on the Acetylene Regulator should nEVER be set above
15 PSI.
12. There must be TWO O-Rings (c24, c25) on the connector (c23) end. The
absence of either O-Ring can lead to flashback within the Torch Handle or Cutting
Attachment.
13. for the cutting Attachment, inspect the tapered seating surfaces on the
Tip and in the Torch Head. Have a qualified technician resurface the seat area
if it has dents, burrs, or is burned. A poor seating surface may result in backfire
or flashback.
14. Backfire and flashback. When the flame goes out with a loud “pop”, it is called
a backfire. Backfire can be caused by (1) operating the Torch at lower pressures
than required for the Tip used, (2) touching the Tip against the workpiece, (3)
overheating the Tip, or (4) an obstruction in the Tip. If backfire occurs, shut off
the Torch Handle Valves (oxygen first) and after remedying the cause, relight the
Torch. A flashback is a condition that results when the flame flashes back into
the Torch and burns inside with a shrill hissing or squealing noise. If flashback
occurs, close the Torch Handle Valves (oxygen first), IMMEDIATELY. Flashback
generally indicates a problem that should be repaired. A clogged Tip, improper
functioning of the Valves, or incorrect acetylene/oxygen pressure could lead to
flashback. Make sure to find the cause before relighting the Torch.
