Operation
8. Check all connections for leaks. Leaks can not
be seen, therefore, use soapy water on all con-
nection points to insure there are no leaks.
9. Open the oxygen control knob on the torch han-
dle two full turns. No oxygen should flow at this
time because the oxygen flow is controlled by
the valve on the cutting head.
10. Insure oxygen flows by turning the control knob
on the cutting head a quarter of turn. Quickly
close the valve after confirming oxygen flow.
11. Press the oxygen cutting lever (1) briefly to con-
firm a stream of oxygen flows from the center
hole in the cutting tip.
12. Slowly open the acetylene tank valve. Open
slowly and not more then 1 turn.
13. Open the acetylene regulator until the regulator
reaches the desired working pressure.
Note: Working pressure charts ar e found on
page 9.
14. Briefly open the acetylene control knob on the
torch handle to confirm acetylene is flowing.
15. Check all connections for leaks using soapy wa-
ter.

Lighting the Torch
Prior to lighting the torch make sure the
hoses are behind the operator and that
there is no chance of them being hit by a
hot spark or slag.
At this point the operator should be wear-
ing appropriate protective clothing such as
gloves and goggles.
1. Open the acetylene control knob on the torch
handle just enough to let some gas flow about a
quarter turn.
2. Holding the striker close to the cutting tip
squeeze it a few times to create the sparks re-
quired to light the acetylene.
Note: A oxy-acetylene torch should NEVER be lit
with oxygen present in the mixture.
Adjusting the Flame
1. Open the oxygen valve on the cutting head.
2. Develop a neutral flame at the preheat holes
(Figure 4) that results in a cone about 1/8th inch
long. This is accomplished by alternately in-
creasing the flow of acetylene and then oxygen.
