ing equipmnet, a medium-size tip,
on your torch. Set the regulators
to 5 psi, and light the flame.
Heat a point on the top of the
steel tube, about 1" from the
right-hand edge. Your torch tip
should be about 1/4" to 3/8" away
from the tube. The flame should be
hitting it at an angle of about 45
degrees. Watch as the steel turns
red. Continue to watch as the
steel starts to "sweat." See it
start to melt. Keep watching as
the puddle expands, until finally,
under its own weight, the puddle
collapses and where it was, there
is now a hole.
This demonstrates the extreme.
You must know how far you can go.
Melt a couple more holes.
