5.6 Gouging.
The Everlast Power Series Plasma func-
tion is able to perform light to medium
gouging, depending upon the type of
metal with the standard cutting tip and
electrode. To gouge, simply lower the air
pressure until the air pressure light sig-
nals low pressure. Allow the air pressure
to stabilize and increase the air pressure
5-10 pounds above the warning light
threshold.
Lean the torch at a 30-35 degree angle to
the work piece and begin to gouge. If you
experience problems, experiment with the
air pressure to accomplish the desired
type of gouge. For certain applications, a
special gouging tip may be required. For
this special need, contact Everlast in ad-
vance of the expected time of need to de-
termine availability of special gouging
electrodes.
5.7 Piercing.
Occasionally, the need will arise to pierce
directly down into a piece of metal to initi-
ate a cut with out the benefit of starting on
the edge of the material. This is known as
piercing. To pierce, simply start the torch
with a 1/8 inch stand-off at the desired
spot. If possible, lean the torch at a slight
angle so that blowback does not become
a problem and will not foul the tip. Make
sure that you tilt the torch away from the
piece being cut out to prevent marring.
Allow the torch to slowly burn its way
through the metal. As the torch plasma
stream burns down through the plate,
straighten the torch into the cutting posi-
tion. As sparks begin to exit the bottom,
you may shorten the stand-off and begin
your cut. Excessive use of piercing will
significantly reduce consumable life, par-
ticularly with an inexperienced operator.
Do not attempt to pierce an object that is
thicker than 50-60% of the rated cut ca-
pacity to ensure long torch life.
Note : Piercing can produce a lot of
blowback of molten metal. Protective
gear is absolutely required, especially
face shields and fire proof clothing.
