SAFETY PRECAUTIONS
DESCRIPTION
WARNING
ELECTRIC SHOCK
can kill.
•
Do not touch electrically live parts
or electrode with skin or wet
clothing.
•
Insulate yourself from work and
ground.
•
Always wear dry insulating
gloves.
The machine is constant current,continuous control
plasma cutting power source. It provides superior
and reliable starting characteristics, cutting visibility
and arc stability. The control system has a safety
mechanism to insure that the nozzle and electrode
are in place before cutting. This is extremely
important due to the high voltages involved.
The machine comes standard with an air regulator
and pressure gauge. The machine also comes with
an input power cord, Hand-held torch with a 4m
cable length. Consumables are included with each
machine purchase so that cutting can begin right
FUMES AND GASES
can be dangerous.
•
Keep your head out of fumes.
•
Use ventilation or exhaust to
remove fumes from breathing
zone.
CUTTING SPARKS
can cause fire or explosion
•
Keep flammable material away.
•
Do not weld, cut or gouge on
containers that have held combustibles.
ARC RAYS
can burn.
•
Wear eye, ear and body
protection.
PLASMA ARC
can injure
•
Keep your body away from nozzle
and plasma arc.
•
Operate the pilot arc with caution. The
pilot arc is capable of burning the
operator, others or even piercing
safety clothing.
out of the box. Consumables can also be ordered as
individual packages.
The machine initiates the plasma arc with a simple,
yet reliable, touch start mechanism. This system
eliminates many of the failure problems associated
with hi-frequency start systems.
PREHEAT TEMPERATURE FOR
PLASMA CUTTING
Preheat temperature control is not necessary in most
applications when plasma arc cutting. Preheat
temperature control may be necessary on high carbon
alloy steels and heat treated aluminum for crack
resistance and hardness control. Job conditions, pre-
vailing codes, alloy level, and other considerations may
also require preheat temperature control. The following
minimum preheat temperature is recommended as a
starting point. Higher temperatures may be used as
required by the job conditions and/or prevailing codes.
If cracking or excessive hardness occurs on the cut
face, higher preheat temperature may be required. The
recommended minimum preheat temperature for plate
thickness up to 1/2" (12.7mm) is 70°F (21.1°C).
Observe additional Safety Guidelines detailed in
the beginning of this manual.
