. a decisive precondition for succeeding with gas
cutting
, irrespec- tive of which fuel gas and nozzle type are being used, is for the fuel gas, heating oxygen and
cutting
oxygen to be present in suf- ficient volumes and with the correct pressure at the
cutting
nozzle. if any of these are absent, a good
cutting
result can never be achieved. for good
cutting
results, read the

table. modern

for both acetylene and propane often have the heating

nozzles
differ from acetylene
nozzles
as the heating
flame
ducts are recessed in relation to the outer nozzle. the extent of the recess varies somewhat according to the type of nozzle, and is normally 0.7 to 1.5 mm. see illustration below. propane has a low burning speed and the recess is necessary to stabi- lise the heating

so that it does not blow out when starting

must be marked in accordance with the standards en 874 for mechanised
