You can make yourself more
steady by resting the back of
your hand on the steel being cut
and rotate your wrist, but non-
flammable gloves are required.

or burning your feet with sparks
and drips of molten steel.

You can cut light gauge steel
without the cutting attachment.
Using a regular torch tip, you
can just melt your way through
beer can gauge steel.

For slightly larger gauge,
preheat with a regular flame,
then turn off the acetylene to
burn a cut with pure oxygen.
Sometimes you have to relight
the flame with acetylene to
continue the cut. Using this
technique, the only pre-heating
comes from the burning of steel
itself.

You can cut non-ferrous
metals with a cutting torch
also, but you will not have the
burning effect. To cut brass
or aluminum, use the pre-heating
flames to melt the metal, then
momentarily blast away the
liquid with cold oxygen. This
technique is slower because you
can cut only 1/4" at a time.
