soda washing soda may be substituted for the sodium
carbonate. Thoroughly scrub all surfaces of the parts.
If immersion treatment is used, continuously stir the
parts in the solution for at least 10 minutes.
After washing, thoroughly rinse the parts with clear
water. Repack the valve with valve packing approved
for oxygen service.
C. MIXER DISK
If necessary, the torch mixer disk can be removed for
cleaning as follows: Remove the two hex nuts and cap
screws used to bolt the preheat mixer body to the cut-
ting oxygen block. Using a wrench, unscrew the mixer
tube connecting nut. Remove the mixer body and in-
vert it. The mixer disk will then fall out.
To clean the mixer disk center orifice, use a No. 5 drill.
To clean the outer orifices use a No. 51 drill. Other
cleaning tools tend to enlarge or bell-mouth the ori-
fices, and should not be used.
If the mixer disk is distorted or the seating surfaces
marred or scratched, it should be replaced with a new
one. In reassembling the mixer disk and mixer tube in
the torch, make sure that the seating surfaces are
clean.

**Preheat oxygen flow is given as 50% of natural gas flow for a 1.5 oxygen to 1.0 natural gas ratio. This oxygen/natural gas ratio produces a long
inner cone flame length which is used for most heavy cutting operations.
