3.1.6. Connect the correct hose to each regulator.
BLUE
to
OXYGEN
and
RED
to
ACETYLENE
. Tighten nuts securely with wrench. If any
sign of oil or grease is found, discontinue use immediately.
3.1.7. Blowing out hoses. Perform this on one hose at a time and in a well ventilated area, otherwise you may create conditions for fire or explosion.
a.Turn the oxygen regulator adjusting screw to allow 5psi to pass through hose.
b.Allow oxygen to flow approximately 10 seconds to purge the hose.
c. Repeat the above steps for acetylene hose.
Note: New hoses contain a preservative powder which must be blown out before use.
3.1.8. Connect the two hoses to the respective connections on the torch handle.
p
WARNING!
If traces of oil or grease are found,
DO NOT
use. Contact your gas supplier immediately.
3.1.9. Always use reverse flow check valves on torch handles.
3.1.10. Always connect welding tip or cutting attachment to torch handle. Always check seal, coupling nut and torch head for damage or oil.
If either is found, discontinue use and contact your supplier.
p
WARNING!
The teflon seal on the torch inlet must not be damaged or missing, otherwise gases will mix inside the torch and result in
flashbacks or backfires.
3.1.11. Check connections for leaks. Adjust the regulators to normal operating pressure and, using an approved leak detection solution, check for
leaks at hose and check valve connections. If a leak is found, tighten nut more securely. If leak persists, discontinue use and call your supplier.
p
WARNING!
Never set acetylene regulator at a delivery pressure above 15psi (1 bar).
3.1.12. Neutral flame adjusting
a.Refer to welding tip or cutting nozzle chart to determine the proper regulator pressures.
b.Open oxygen valve on the torch handle (and preheat oxygen valve on cutting attachment). Adjust the oxygen regulator to the desired
working pressure, and then close the oxygen valve.
c. Open acetylene valve on the torch handle, adjust the acetylene regulator to the desired working pressure. Then close the acetylene valve.
d.Hold torch in one hand and spark lighter in the other.
e.Open the acetylene torch valve about 1/4 turn and ignite the acetylene gas coming out of the tip.
p
WARNING!
Always point torch away from person when lighting.
f. Turn on the acetylene torch valve slowly until smoke subsides and the flame jumps away from the end of the tip slightly.
g.Slowly open the oxygen valve until a brilliant neutral flame is reached.
p
WARNING!
Always use goggles or eye protection when welding or cutting.
3.2.
Shutting down and leaving safe
3.2.1. Turn off the acetylene valve on the torch and
then
turn off the oxygen valve on the torch.
Note: Reversal of this procedure can cause damage to the torch.
3.2.2. Close both cylinder valves.
3.2.3. Drain gas from oxygen regulator by opening the oxygen valve on the torch handle. Similarly drain gas from the acetylene regulator.
3.2.4. Release adjusting screws on regulators. This is done by turning them anti-clockwise.
