produces a cut of this type. The combustion
and melting of the steel always follows the

oxygen pressure causes undue expansion of
the gas as it leaves the torch tip. This results
in excessive turbulence which gives the

thick and sticks to the surface. Top portion of
cut is undercut. Slag is stuck to the bottom of
the cut. A cut such as this also must be
machined or ground to make it suitable for
welding.
