APPLICATIONS AND CHARACTERISTICS
General cutting operations, medium preheat.
Dirty, heavily coated metals. Rugged use (scrapping, heavy construction).
Used where excessive reflected heat is present.
Dirty, coated metal. Heavy preheat for faster starts.
CAUTION: Manifolding may be necessary for large tips with acetylene.
Coated metals. Heavy preheat for faster starts. Excellent for scrapping operations.
General cutting operations, medium preheat.

TIP CHART INFORMATION
PRESSURE AND FLOW DATA: Cutting data charts are intended
as a guide for quality cutting. The data was gathered under ideal shop
conditions and on new, clean steel using three-hose machine cutting
torches mounted on a portable cutting machine. All pressure settings are
flowing pressures. Unless noted otherwise data is based on 25’ (7.6m)
of
1
/
4
” (6mm) I.D. hose. Pressure must be increased if longer or smaller
I.D. hose is used. Preheat flow will normally yield 4-6 second edge starts
and 15-20 second pierce starts on 1” (25.4mm) material for SC series
cutting tips, and on
1
/
2
” (13mm) material for MC series tips.
HOSES: Do not use excessively long hoses or hoses with many hose
unions, either will restrict gas flow and pressure causing lower cutting
efficiency and possibly leading to dangerous operating conditions.
MANIFOLDING CYLINDERS: When required flows (cubic feet
per hour - SCFH) exceed the recommended withdrawal rate from
one cylinder then additional cylinders must be manifolded to provide
safe and efficient operation. Acetylene must not be withdrawn at more
than
1
/
7
of the cylinder capacity (47 SCFH for a 330 cu. ft. cylinder).
Consult your gas supplier for manifolding instructions for the gases and
cylinders supplied to you.
AVAILABILITY: Some tips included in Technical Data may no longer be
available. Non-current tips have been included in this section for cross
reference purposes.
CAUTION: When using liquid oxygen, tips may require greater
gas volume than a single cylinder is capable of producing. External evaporators or manifolding multiple
cylinders may be necessary to supply sufficient gas flows.
