OXYGEN AND ACETYLENE SET UP AND INSTRUCTIONS
ATTACHING THE REGULATORS
Open cylinder valve slightly to blow out dirt, then close. Attach regulators, tighten the
connections firmly, attach the hoses to the regulators, and tighten.
NOTE: The acetylene hose connections are left hand threads, and the oxygen
connections are right hand threads.
ATTACHING THE TORCH
Attach acetylene hose (RED) to torch valve marked “AC”, note the left hand
thread. Attach oxygen “OX”, note right hand thread. Shut both valves on torch
before opening cylinders.
OPENING THE VALVES
Be sure adjusting keys of regulators are free, that is, turned counter clockwise until
loose. Open oxygen tank valve and acetylene tank valve slowly.
ADJUSTING PRESSURE
Screw the adjusting key on each regulator until the desired working pressure for each
gas is reached. This is shown on the low pressure (left) gauge on each regulator. The
high pressure (right) gauge indicates how much pressure is in the cylinder. Proper
pressures are shown on the tip charts on page 11.
INSTALLING THE CUTTING TIP
Remove tip nut from cutting attachment. Place tip into the nut and then wind nut firmly
into place using a wrench.
TO LIGHT THE TORCH
Open the torch fuel valve approximately one half turn and ignite the acetylene. Keep
opening the torch fuel valve until the flame stops smoking excessively and leaves the
end of the tip about 1/8”, then reduce slightly to bring flame back to tip. Open the
torch oxygen valve until a bright inner cone appears on the flame. The point at which
the feathery edges of the flame disappear and a sharp inner cone is visible is called
the “Neutral Flame”.
