7. Allow post/after flow cooling to occur.
Post flow will continue for
up to a half a minute after
the cut is completed. If ad-
ditional cooling is required
because of heavy cutting or
extended cutting, switch
the post flow switch to
“Test” to start manual cooling of the torch.
After the torch is sufficiently cooled, return
the switch to cutting mode to discontinue
the post/after flow cooling cycle.
5.4 Helpful Hints for cutting.
1. Make several practice cuts first. Adjust
the amperage and air pressure throughout
the range to see the effects it has on the
cut. Each machine will have a slightly dif-
ferent range or “sweet spot”.
2. Use a substantial flat piece of metal to
make a long, clean cut. Attempting to cut
odd objects or make short cuts cannot
really train proper technique. It will also be
difficult to ascertain the quality of the cut.

Settings.
3. Keep torch straight in cut. Do not lean
or tilt the torch. The ergonomic design of
Everlast’s torches eases this problem.
However, fatigue is a common cause for
poor, uneven cuts.
4. Keep consumables checked for wear.
Tip wear can decrease cutting capacity and
cut quality at an imperceptible rate until
cutting ability is significantly affected.
4. Continue cutting following the desired
path of cut. Make sure
that the sparks are exiting
the piece of metal at a 10-
15 degree angle. If the
sparks are exiting straight
down, then the cutting
speed is too slow. In-
crease cutting speed until
a change of the spark an-
gle is observed. If exces-
sive slag is building up on the bottom of the
metal (more than 1/8 inch) then either in-
crease amperage, travel speed or air pres-
sure. Sometimes excessive slag build up on
the bottom of the cut occurs because the
machine has reached its severance limit.
Occasionally excessive slag can be caused
by rusty or contaminated metal. Note that
cutting thicknesses posted in the specifica-
tion page are specifically for mild carbon
steel under ideal circumstances. Stainless,
Aluminum and other metals have reduced
cut ratings. Cutting capacity of these met-
als are generally 10-20% less than mild
steel.
5. Exit the cut by pausing briefly to allow
the spark stream to catch
up and to be directed
straight down. This is usu-
ally the most challenging
part of the cut because the
bottom of the cut needs to
be even with the top before
exiting or the cut piece will
remain stuck to the parent
piece of metal. Carefully work the plasma
stream to the very edge of the cut.
6.Release the trigger to break the arc in
the Standard mode setting.
In the Automatic mode set-
ting, repress the trigger
and release to discontinue
the arc.
Caution! Breaking the
arc in the auto mode by lifting the arc away
will not satisfactorily terminate the arc and
may restart the pilot arc. Precautions must
be taken in this mode or serious injury can
occur.
