Cutting Tip Data
IMPORTANT:Use proper type seat cutting tips for each type of torch and fuel gas.
Use proper type tips for fuel gases or acetylene.See manufacture's chart for proper tip
selection. Use proper tip size, pressures and flamesize to avoid backfire and flashback.

* The approx. Oxygen consumption ration for various gasses is as follows:
1 oxygen to 1 acetylene
2 oxygen to 1 Mapp®/Natural gas
4 oxygen to 1 propane/propylene
Gas consumption data is merely for estimating purposes. It will vary due to the material,
skill of the operator and working conditions
**Use same pressures for fuel gas for brazing and one size or larger tip. Pressures are
approximate for hose lenght up to 25ft, increase for longer lengths about 3 psi for every
25ft, increase working pressure 2-3 psi for check valves.NOTE: Oxy-acetylene must
be used to produce satisfactory welds in steel.
Acetylene cylinder gas withdrawal should not exceed 1/7 (15%) of cylinders contents per
hour. Do not allow gas cylinders (especially oxygen) to empty in use - this can cause
unbalanced pressures and reverse flow of gasses. An adequate cylinder of manifold system
should be provided for large gas usage operations with 3/8" hose for larger size
tips. Approximate heat output B.T.U./HR. per cubic foot: acetylene 1470, propane 2498,
Mapp® 2406 propylene 2371, natural gas 1000.

* Use 3/8" hose on large tips for more gas flow.
** Type 12 for fule gas only (Not Acetylene)
***IMPORTANT:Use maximum pressure on large heating tips to avoid backfire and
flashback conditions from low gas flows. Fuel gas flame must have excessive smoking
cleared to provide adequate gas flow increase fuel regulator pressure enough to clear
smoke from flame.
