direction of cut.  When cutting with
power, the operator must use a
protective lens shade #10 or higher to
protect from arc flash.

FIGURE 3 Cutting With Power

Hole Piercing

Most piercing operations should be
done without power.  To pierce a
hole, ignite the cutting rod as
explained in the cutting-without-
Power section.  Move the burning rod
to the pierce point and with the rod
angled away from the operator, begin
piercing the hole.  Once the hole is
under way, bring the cutting rod
perpendicular to the surface of the
workpiece.  Keep the cutting rod deep
enough in the hole to feel slight
resistance from the non-molten
material at the base of the hole.
While the hole is being pierced, use a
slight circular motion to keep the rod
free of molten material coming out of
the hole.  During the piercing
operation, the rod should be moved in
and out of the hole occasionally to
maintain an open path for the molten
material.

During a piercing operation the
molten material will be coming back
up the rod.  Wear proper clothing for
protection from the molten spray.
The torch should be held at arm's
length to keep the operator as far
away from the molten material as
possible.  To protect the operator and

torch, an optional 6" collet extension
and extension shield are available for
the SLICE cutting torch.

Piercing in the flat position is more
difficult than piercing horizontally.
Progression while piercing flat will
also be slower. (Example: Piercing a
hole in a floor is more difficult and
slower than piercing a hole in a wall.)

Cutting Copper and Copper
Alloys

Because of the very rapid heat
absorption of copper and its alloys, all
cutting on these materials should be
done with power.  The maximum
amperage to use with copper is 300
amperes.  Copper quickly absorbs
the heat created from the exothermic
reaction, reducing the effectiveness
of the cutting process.  The heat is
stronger when cutting with power,
making it possible to cut some copper
pieces.  The larger the size of the part
the more difficult it is to cut.  A sawing
motion into the cut kerf will speed
cutting.

Piercing Copper and Copper
Alloys

When piercing copper and its alloys,
use power.  Using power to pierce
copper will cause extremely fast rod
consumption.  The higher the copper
content of the part the harder the
material is to cut.  Brass, bronze and
other alloys are slightly easier to cut,
but these alloys should be cut using
power, if possible.

EQUIPMENT SELECTION

SLICE Torch and Striker

The SLICE Torch is a gun shaped
tool that provides a means of gripping
the rod and supplying the oxygen and
power to the cutting rod. The basic
torch comes complete with 10 feet of

TORCH
