SET UP AND OPERATING GUIDE
1. Secure cylinders. (As noted in safety precautions.)
2. While standing to one side, “crack” each cylinder valve. (fig. 2)
“Cracking” is to quickly open and close the valve, allowing
gas to escape and clearing the valve of any foreign
material.
If oil or grease is found, discontinue use of
cylinder immediately and contact your supplier.

Cylinders are highly pressurized. Handle
with extreme care. Never allow cylinders to be knocked over,
dropped, or subjected to excessive heat.

f. Turn on the acetylene torch valve slowly until smoke
subsides and the flame jumps away from the end of the
tip slightly. (fig. 11)

flame is reached. (fig. 12) (If the flame has a smooth
inner cone the flame is neutral)

Adjusting Flame
Neutral Flame
Flame setting is increased by opening the
torch control valves or increasing the operating pressure.
Never
reduce
the flame setting. This will cause the tip or nozzle to
overheat which will result in flashback.
If less heat is required,
use a smaller tip or nozzle
.
