6. Connect proper hose to regulator. (Green to oxygen and
red to acetylene.) Tighten nuts securely with wrench. (fig. 6)
If any sign of oil or grease is found, discon-
tinue use immediately.
7. Blowing out hoses: Do this to one regulator at a time and in
a well ventilated area to avoid creating conditions for fires
or explosions.
a. Turn oxygen regulator adjusting screw to allow 5 PSIG
to pass through hose.
b. Allow oxygen to flow approximately 10 seconds to purge
the hose.
c. Repeat these steps for acetylene regulator.
Note: New hose contains a preservative talc which must be
blown out before using.

8. Connect hoses to the
check valve that is installed
on the
torch handle. (Oxygen is right-handed and fuel gas is
left-handed.) (fig 7)
If any traces of oil or grease are found, do
not use. Contact your supplier immediately.

9. Connect cutting attachment, welding or heating nozzle to
the torch handle. (fig 9)
There must be two(2) “o” rings on the cone
end in an undamaged condition. The absence of either “o” ring
creates a condition that allows pre-mixing of oxygen and fuel
gases. This can lead to flashback within the torch handle or
cutting attachment. (fig 8)
Always check cone end coupling nut and torch head for
damage or oil presence. If either are found contact your
supplier.
