1.0 Safety Warnings
WARNING
1.1 General Precautions
Whereas plasma cutting has been used
safely for years, it does require certain
precautions to ensure the safety of the
operator and other people around the
equipment. The following safety information
must be provided to each person who will
operate, observe, perform maintenance, or
work in close proximity to this piece of
equipment. Always wear appropriate
personal protective equipment (PPE).
Installation, operation, and repairs made to
this System should only be performed by
qualified personnel. The System makes use
of both A.C. and D.C. circuitry for operation.
Fatal shock hazard does exist. Exercise
extreme caution while working on the
System.
1.2 California Proposition 65
This product, when used for welding or
cutting, produces fumes or gases which
contain chemicals known to the State of
California to cause birth defects and, in
some cases, cancer. (California Health &
Safety Code § 25249.5 et seq.)
WARNING: Cancer and Reproductive Harm
www.p65warnings.ca.gov
1.3 Ultraviolet Radiation
Protection
Plasma cutting produces
ultraviolet radiation similar to
a welding arc. This ultraviolet
radiation can cause skin and
eye burns. For this reason, it
is essential that proper protection be worn.
The eyes are best protected by using safety
glasses or a welding helmet with an AWS
No. 12 shade or ISO 4850 No. 13 shade,
which provides protection up to 400
amperes. All exposed skin areas should be
covered with flame-retardant clothing. The
cutting area should also be prepared in
such a way that ultraviolet light does not
reflect. Walls and other surfaces should be
painted with dark colors to reduce reflected
light. Protective screens or curtains should
be installed to protect additional workers in
the area from ultraviolet radiation.
1.4 Fire Prevention
When using this System, it is
necessary to exercise good
judgment. While cutting, the
arc produces sparks that
could cause a fire if they fall
on flammable materials. Make sure that all
flammable materials are a suitable distance
away from the cutting area. All flammable
liquids should be at least 40 feet away from
the cutting area, preferably stored in a
metal cabinet. Plasma cutting should never
be attempted on containers that contain
flammable materials. Make sure that fire
extinguishers are readily accessible in the
cutting area.
Make sure that the cutting area is properly
ventilated when using oxygen as a cutting
gas.

Page 6 of 132
WARNING
1.5 Noise Protection
The System generates high
noise levels while cutting.
Depending on the size of the
cutting area, distance from the
cutting torch, and arc current
cutting level, acceptable noise levels may
be exceeded. Proper ear protection should
be used as defined by local or national
codes. Refer to Section 2.12 for noise
emission levels.
1.6 Toxic Fume Prevention
Care should be taken to
ensure adequate ventilation
in the cutting area. Some
materials give off toxic
fumes that can be harmful
or fatal to people in the vicinity of the cutting
area. Also, some solvents decompose and
form harmful gases when exposed to
ultraviolet radiation. These solvents should
be removed from the area prior to cutting.
Galvanized metal can produce harmful
gases during the cutting process. Ensure
proper ventilation and use breathing
equipment when cutting these materials.
Certain metals coated with or containing
lead, cadmium, zinc, beryllium, and
mercury produce harmful toxins. Do not cut
these metals unless all people subjected to
the fumes wear proper air breathing
equipment.
1.7 Health Support Equipment
The System creates electric
and magnetic fields that
may interfere with certain
types of health support
equipment, such as
pacemakers. Any person
who uses a pacemaker or similar item
should consult a doctor before operating,
observing, maintaining, or servicing the
System. Observe the following guidelines to
minimize exposure to these electric and
magnetic fields:
•Stay as far away from the Power Supply,
torch, torch leads, and arc start console
as possible.
•Route the torch leads as close as possible
to the work ground cable.
•Never place your body between the torch
leads and work ground cable. Keep the
work ground cable and the torch leads on
the same side of your body.
•Never stand in the center of a coiled up
set of torch leads or work ground cable.

WARNING
1.8 Electric Shock Prevention
The System uses high open
circuit voltages that can be
fatal. Extreme care should be
used when operating or
performing maintenance on the
System. Only qualified personnel should
service the System. Observe the following
guidelines to protect against electric shock:
•A wall-mounted disconnect switch should
be installed and fused according to local
and national electrical codes. The
disconnect switch should be located as
close as possible to the Power Supply so
it can be turned off in case of an
emergency.
•The primary power cord should have a
600 volt minimum rating in order to protect
the operator. In addition, it should be
sized according to local and national
electrical codes. Inspect the primary
power cord frequently. Never operate the
System if the power cord is damaged in
any way.
•Make sure the primary power ground wire
is connected to the input power ground
stud on the Power Supply. Make sure the
connection is securely tightened.
•Make sure the positive output (work
ground) of the Power Supply is connected
to a bare metal area on the cutting table.
A driven ground rod should be placed no
further than five feet from this connection.
Make sure this ground point on the cutting
table is used as the star ground point for
all other ground connections.
•Inspect the torch leads frequently. Never
use the System if the leads are damaged
in any way.
•Do not stand in wet, damp areas when
operating or performing maintenance on
the System.
•Wear insulated gloves and shoes while
operating or performing maintenance on
the System.
•Make sure the System is switched off at
the wall disconnect before servicing the
Power Supply or torch.
•Never change torch consumable parts
unless the System is switched off at the
wall disconnect.
•Do not attempt to remove any parts from
beneath the torch when cutting.
Remember that the workpiece forms the
current path back to the Power Supply.
•Never bypass the safety interlock devices.
•Before removing any of the covers, switch
the System off at the wall disconnect.
Wait at least five (5) minutes before
removing any cover. This will give the
capacitors inside the unit time to
discharge.
•Never operate the System without all of
the covers in place.
•Preventive maintenance should be
performed daily to avoid possible safety
hazards.

•Never operate the System in the presence
of explosive gases or other explosive
materials.
•Never cut pressurized cylinders or any
closed container.
•When using a water table and cutting
aluminum under water or with water
touching the underside of the aluminum
plate, hydrogen gas is produced. This
hydrogen gas may collect under the plate
and explode during the cutting process.
Make sure the water table is properly
aerated to help prevent the accumulation
of hydrogen gas.
•Handle all gas cylinders in accordance
with safety standards published by the
U.S. Compressed Gas Association
(CGA), American Welding Society (AWS),
Canadian Standards Association (CSA),
or other local or national codes.
•Compressed gas cylinders should be
maintained properly. Never attempt to use
a cylinder that is leaking, cracked, or has
other signs of physical damage.
•All gas cylinders should be secured to a
wall or rack to prevent accidental knock
over.
•If a compressed gas cylinder is not being
used, replace the protective valve cover.
•Never attempt to repair compressed gas
cylinders.
•Keep compressed gas cylinders away
from intense heat, sparks, or flames.
•Clear the compressed gas cylinder
connection point by opening the valve
momentarily prior to installing a regulator.
•Never lubricate compressed gas cylinder
valves or pressure regulators with any
type of oil or grease.
•Never use a compressed gas cylinder or
pressure regulator for any purpose other
than which it is intended.
•Never use a pressure regulator for any
gas other than which it is intended.
•Never use a pressure regulator that is
leaking or has other signs of physical

2.5 Cooling System and Torch Coolant
Cooling System (located inside the Power Supply):
Discharge pressure....................................................175 psi (12.07 bar)
Flow rate ........................................................ 1.5 gal/min (5.7 liters/min)
Coolant fluid..................................................... Propylene glycol solution
Reservoir capacity .................................................... 5.0 gal (18.9 liters)
Maximum coolant temperature .......................................... 149°F (65°C)
The torch coolant solution consists of 25% industrial grade propylene glycol and
provides freeze protection down to 9º F (-13º C). Torch coolant can be ordered in
1.0 gallon (3.8 liter) containers, part number BK500695.
DO NOT USE automotive or other commercial anti-freeze that contains rust
inhibitors or leak stoppers. These coolants will damage the pump and block the
small internal passageways in the heat exchanger, affecting cooling performance.
To avoid freeze damage and fluid leakage during shipment, the Power Supply is
delivered with very little coolant in the reservoir. DO NOT OPERATE the System
until it has been filled with coolant.
After the initial filling and after coolant flushes, additional coolant will be required
because the coolant hoses and torch leads will also fill with coolant. Longer runs
require more coolant than shorter runs.
Refer to the Safety Data Sheet (SDS) supplied with the torch coolant for complete
information regarding first aid, handling, storage, transportation and proper disposal.

Oxygen and nitrogen should be supplied with a purity of at least 99.5%. H17 purity
should be at least 99.995%. Argon purity should be at least 99.99%. All should be
clean, dry and oil-free.
A potential fire hazard exists when cutting with oxygen. It is recommended that an
exhaust ventilation system be used when cutting with oxygen. Flashback arrestors
must be supplied (unless they are not available for the chosen gases and pressures)
to prevent a possible fire from propagating back to the gas supplies.
Ensure that oxygen lines remain free from contaminants such as oil and grease. The
mixture of such contaminants with oxygen presents an additional fire hazard.
Compressed air must be clean, dry, and oil-free and may be supplied from
compressed cylinders or from an air compressor. Be aware that shop air systems
are prone to oil and moisture contamination. If shop air is used, it must be cleaned to
ISO 8573.1: Class 1.4.1. Specify dry air when using compressed cylinders.
Breathing quality air contains moisture and must not be used.
3/8” (inside diameter) hoses are required for all inlet gas connections. Mating
connectors are available as an option. Quick-connect fittings must not be used.
