BOC used to supply a welding guide (Publication TC 1430) with their
'PortaPak' welding equipment.

The lighting up procedure specified in the guide is, acetylene on first
adjusted 'until the flame just ceases to smoke'. Then slowly feed in
oxygen 'until the white cone of the flame is sharply defined with the
merest trace of acetylene haze.'

Shutting down is the reverse - shut off the acetylene completely and then
shut off the oxygen.

These were the instructions supplied about 30 years ago and as far as I
know they're still the same today.

Just in case nobody else has told you - don't use any oil on the gauges /
threads etc. It can be verydangerous.

Same as we do with O2/H2 welding kit.
