BACKFIRE:
When the flame goes out with a loud “pop,” it is
called a
backfire.
Backfire can be caused by:
a. Operating the Torch at lower pressures
than required for the Tip used.
b. Touching the Tip against the workpiece.
c. Overheating the Tip.
d. An obstruction in the Tip.
If backfire occurs, close the Torch Handle Valves
(oxygen first, then acetylene) and after
remedying the cause, relight the torch.
9.
FLASHBACK:
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, then acetylene) IMMEdIATELy!
Flashback generally indicates a problem that should
be repaired before proceeding with the job at hand.
A clogged Tip, improper functioning of the Valves,
or incorrect acetylene/oxygen pressure could lead
to flashback. Find and correct the cause before
relighting the Torch.
If the cause is not found, have the kit serviced by a
qualified technician before returning to your project.
10.
Beware of leaking gas.
If you notice the odor of acetylene during use,
close the Torch Handle Valves
(oxygen first, then acetylene) IMMEdIATELy!
Extinguish all open flames and carefully check all
hoses and connections for leaks using soapy water.
NEVER check for leaks using a flame.
If the odor continues do not use the Torch.
Call acetylene supplier for assistance.
11.
Read and understand all instructions and safety
precautions as outlined in the manufacturer’s
manual for the material you will weld or cut.
12.
After use, bleed lines and store all
components out of reach of children and
other untrained persons.
Torches are
dangerous in the hands of untrained users.
