[TheForge] learning to use a cutting torch properly

Wed May 28 22:04:01 2003

I have never seen a good torch reference.

two things are key

1 the flame must be neutral

2 size your flame for your material bigger is not better unless you have 2
or 3" thick steel.

Neutral flame adjustment

Set your regulators to 7 PSI acetylene and 15 PSI oxygen.  Some people will
tell yopu thats high on the gas side but thats what we use in the shop and
it works the best.

For thin material 1/8 or less, open the aceytlene and strike a flame adjust
it so that the flame is about 8 to 9 incehs long, then turn on the ogygen
till the flame turns blue.   Next depress the cutting lever and while
holding it down adjust the flame till all of the light blue cones turn to a
bright blue, play with this a few times if you have not already, as a
hissing or oxidizing flame leaves a messy cut.

Chances are also that much of the torch work you see is now plasma cut,
while you can get fancy with a toirck, the cleanup end of things is always
more time consuming.
