GENERAL INFORMATION

1.01 Notes, Cautions and Warnings

Throughout this manual, notes, cautions, and warnings
are used to highlight important information. These high­lights are categorized as follows:

NOTE

An operation, procedure, or background informa­tion which requires additional emphasis or is help­ful in efficient operation of the system.

CAUTION

A procedure which, if not properly followed, may
cause damage to the equipment.

WARNING

A procedure which, if not properly followed, may
cause injury to the operator or others in the oper­ating area.

1.02 Important Safety Precautions

WARNINGS

OPERATION AND MAINTENANCE OF
PLASMA ARC EQUIPMENT CAN BE DAN­GEROUS AND HAZARDOUS TO YOUR
HEALTH.

Plasma arc cutting produces intense electric and
magnetic emissions that may interfere with the
proper function of cardiac pacemakers, hearing aids,
or other electronic health equipment. Persons who
work near plasma arc cutting applications should
consult their medical health professional and the
manufacturer of the health equipment to determine
whether a hazard exists.

To prevent possible injury, read, understand and
follow all warnings, safety precautions and instruc­tions before using the equipment. Call 1-603-298­5711 or your local distributor if you have any ques­tions.

GASES AND FUMES

Gases and fumes produced during the plasma cutting
process can be dangerous and hazardous to your health.

• Keep all fumes and gases from the breathing area.
Keep your head out of the welding fume plume.

• Use an air-supplied respirator if ventilation is not
adequate to remove all fumes and gases.

• The kinds of fumes and gases from the plasma arc
depend on the kind of metal being used, coatings
on the metal, and the different processes. You must
be very careful when cutting or welding any met­als which may contain one or more of the follow­ing:

Antimony Chromium Mercury
Arsenic Cobalt Nickel
Barium Copper Selenium
Beryllium Lead Silver
Cadmium Manganese Vanadium

• Always read the Material Safety Data Sheets
(MSDS) that should be supplied with the material
you are using. These MSDSs will give you the in­formation regarding the kind and amount of fumes
and gases that may be dangerous to your health.

• For information on how to test for fumes and gases
in your workplace, refer to item 1 in Subsection 1.03,
Publications in this manual.

• Use special equipment, such as water or down draft
cutting tables, to capture fumes and gases.

• Do not use the plasma torch in an area where com­bustible or explosive gases or materials are located.

• Phosgene, a toxic gas, is generated from the vapors
of chlorinated solvents and cleansers. Remove all
sources of these vapors.

• 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 Sec. 25249.5 et seq.)

ELECTRIC SHOCK

Electric Shock can injure or kill. The plasma arc process
uses and produces high voltage electrical energy. This
electric energy can cause severe or fatal shock to the op­erator or others in the workplace.

• Never touch any parts that are electrically “live” or
“hot.”

October 5, 2006 1-1 GENERAL INFORMATION

• Wear dry gloves and clothing. Insulate yourself
from the work piece or other parts of the welding
circuit.

• Repair or replace all worn or damaged parts.

• Extra care must be taken when the workplace is
moist or damp.

• Install and maintain equipment according to NEC
code, refer to item 9 in Subsection 1.03, Publications.

• Disconnect power source before performing any ser­vice or repairs.

• Read and follow all the instructions in the Operat­ing Manual.

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag, sparks, or
the plasma arc.

• Be sure there is no combustible or flammable mate­rial in the workplace. Any material that cannot be
removed must be protected.

• Ventilate all flammable or explosive vapors from
the workplace.

• Do not cut or weld on containers that may have held
combustibles.

• Provide a fire watch when working in an area where
fire hazards may exist.

• Hydrogen gas may be formed and trapped under
aluminum workpieces when they are cut underwa­ter or while using a water table. DO NOT cut alu-
minum alloys underwater or on a water table un­less the hydrogen gas can be eliminated or
dissipated. Trapped hydrogen gas that is ignited
will cause an explosion.

NOISE

Noise can cause permanent hearing loss. Plasma arc pro­cesses can cause noise levels to exceed safe limits. You
must protect your ears from loud noise to prevent per­manent loss of hearing.

• To protect your hearing from loud noise, wear pro­tective ear plugs and/or ear muffs. Protect others
in the workplace.

• Noise levels should be measured to be sure the deci­bels (sound) do not exceed safe levels.

• For information on how to test for noise, see item 1
in Subsection 1.03, Publications, in this manual.

PLASMA ARC RAYS

Plasma Arc Rays can injure your eyes and burn your skin.
The plasma arc process produces very bright ultra violet
and infra red light. These arc rays will damage your eyes
and burn your skin if you are not properly protected.

• To protect your eyes, always wear a welding hel­met or shield. Also always wear safety glasses with
side shields, goggles or other protective eye wear.

• Wear welding gloves and suitable clothing to pro­tect your skin from the arc rays and sparks.

• Keep helmet and safety glasses in good condition.
Replace lenses when cracked, chipped or dirty.

• Protect others in the work area from the arc rays.
Use protective booths, screens or shields.

• Use the shade of lens as suggested in the following
per ANSI/ASC Z49.1:

Minimum Protective Suggested

Arc Current Shade No. Shade No.

Less Than 300* 8 9

300 - 400* 9 12

400 - 800* 10 14

* These values apply where the actual arc is clearly
seen. Experience has shown that lighter filters may
be used when the arc is hidden by the workpiece.

Art # A-04256

I. Cutting Operation

Refer to the manual supplied with the torch for details on cutting operation, cutting speeds, parts selection and replacement,
etc.

When the torch leaves the workpiece during cutting operations with the RUN / Rapid Auto Restart / SET switch in the RUN
(up) position, there is a brief delay in restarting the pilot arc. With the switch in the 'Rapid Auto Restart' (middle) position,
when the torch leaves the workpiece the pilot arc restarts instantly, and the cutting arc restarts instantly when the pilot arc
contacts the workpiece. Use the 'Rapid Auto Restart' position when cutting expanded metal or gratings, or in gouging or
trimming operations when an uninterrupted restart is desired.

NOTE

When the shield cup is properly installed, there is a slight gap between the shield cup and the torch handle. Gas
vents through this gap as part of normal operation. Do not attempt to force the shield cup to close this gap. Forcing
the shield cup against the torch head or torch handle can damage components.

J. Typical Cutting Speeds

Cutting speeds vary according to torch output amperage, the type of material being cut, and operator skill. Refer
to the Torch Manual for details.

Output current setting or cutting speeds may be reduced to allow slower cutting when following a line, or using
a template or cutting guide while still producing cuts of excellent quality.

Manual 0-4668 4-5 OPERATION

K. Postflow

Release the trigger to stop the cutting arc. Gas continues to flow for approximately 20 seconds. During post - flow,
if the user moves the trigger release to the rear and presses the trigger, the pilot arc starts. The main arc transfers to
the workpiece if the torch tip is within transfer distance to the workpiece.

L. Shutdown

Turn the ON / OFF switch to OFF (down). All Power Supply indicators shut off. Unplug the input power cord or disconnect
input power. Power is removed from the system.

OPERATION 4-6 Manual 0-4668

SECTION 5:

SERVICE

5.01 General Maintenance

A. O-Ring Lubrication

An O-ring on the Torch ATC Male Connector requires lubrication on a regular basis, depending on how frequently
the torch is disconnected and re-connected. This will allow the O-ring to remain pliable and provide a proper seal.
The O-ring will dry out, becoming hard and cracked, if the O-ring lubricant is not used on a regular basis. This can
lead to potential performance problems.

It is recommended to apply a very light film of O-ring lubricant (Catalog # 8-4025) to the o-ring on a weekly basis.

NOTE

DO NOT use other lubricants or grease, they may not be designed to operate within high temperatures or may contain

“unknown elements” that may react with the atmosphere. This reaction can leave contaminants inside the torch.
Either of these conditions can lead to inconsistent performance or poor parts life.

APPENDIX 3: MAINTENANCE SCHEDULE

This schedule applies to all types of non-liquid cooled plasma cutting systems. Some systems will not have all the parts
listed and those checks need not be performed.

NOTE

The actual frequency of maintenance may need to be adjusted according to the operating environment.

Daily Operational Checks or Every Six Cutting Hours:

1. Check torch consumable parts, replace if damaged or worn.

2. Inspect torch for any cracks or exposed wires, replace if necessary.

3. Check plasma and secondary supply and pressure/flow.

4. Purge plasma gas line to remove any moisture build-up.

5. Inspect input power cable for damage or exposed wires, replace if necessary.

Weekly or Every 30 Cutting Hours:

1. Check fan for proper operation and adequate air flow.

2. Blow or vacuum dust and dirt out of the entire machine.

CAUTION

Do not blow air into the power supply during cleaning. Blowing air into the unit can cause metal particles to interfere
with sensitive electrical components and cause damage to the unit.

Six Months or Every 720 Cutting Hours:

1. Check the in-line air filter(s), clean or replace as required

2. Check cables and hoses for leaks or cracks, replace if necessary.

3. Check all contactor points for severe arcing or pits, replace if necessary.
