1.02Important Safety Precautions
• 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:
• 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.)
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 1-603-298-5711 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.
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.”
• 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.
Manual 0-4805
1-1
AUTO-CUT 200
• 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 aluminum 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.

The torch is designed for use with a power supply which senses coolant return flow to confirm that torch
parts are in place. If coolant return flow to the power supply is absent or insufficient the power supply will
not provide power to the torch. Coolant leakage from the torch also indicates that torch parts are absent
or installed improperly.

3.06 Ground Connections
A. Electromagnetic Interference (EMI)
Pilot arc starting generates a certain amount of electromagnetic interference (EMI), commonly called RF noise.
This RF noise may interfere with other electronic equipment such as CNC controllers, remote controls, height
controllers, etc. To minimize RF interference, follow these grounding procedures when installing mechanized
systems:
B. Grounding
1. The preferred grounding arrangement is a single point or “Star” ground. The single point, usually on the cutting
table, is connected with 1/0 AWG (European 50 mm2) or larger wire to a good earth ground (measuring leass
than 3 ohms; an ideal ground measures 1 ohm or less. Refer to paragraph ‘C’, Creating An Earth Ground. The
ground rod must be placed as close as possible to the cutting table, ideally less than 10 ft (3.0 m), but no more
than 20 ft (6.1 m) from the cutting table.
NOTE
All ground wires should be as short as possible. Long wires will have increased resistance to RF
frequencies. Smaller diameter wire has increased resistance to RF frequencies, so using a larger
diameter wire is better.
2. Grounding for components mounted on the cutting table (CNC controllers, height controllers, plasma remote
controls, etc.) should follow the manufacturer’s recommendations for wire size, type, and connection point
locations.
For Thermal Dynamics components (except Arc Starter and Gas Control Module) it is recommended to use a
minimum of 10 AWG (European 6 mm2) wire or flat copper braid with cross section equal to or greater than 10
AWG connected to the cutting table frame. The Remote Arc Starter uses 1/0 earth ground wire and the Gas
Control Module should use minimum # 4 AWG wire. The connection point must be to clean bare metal; rust and
paint make poor connections. For all components, wires larger than the recommended minimum can be used
and may improve noise protection.
3. The cutting machine frame is then connected to the “Star” point using 1/0 AWG (European 50 mm2) or larger
wire.
4. The plasma power supply work cable (see NOTE) is connected to the cutting table at the single point “Star” ground.
NOTE
Do Not connect the work cable directly to the ground rod.
5. Make sure work cable and ground cables are properly connected. The work cable must have a solid connection
to the cutting table. The work and ground connections must be free from rust, dirt, grease, oil and paint. If
necessary grind or sand down to bare metal. Use lock washers to keep the connections tight. Using electrical
joint compound to prevent corrosion is also recommended.
6. The plasma power supply chassis is connected to the power distribution system ground as required by electrical codes. If the plasma supply is close to the cutting table (see NOTE) a second ground rod is not usually
needed, in fact it could be detrimental as it can set up ground loop currents that cause interference.
When the plasma power supply is far away from the ground rod and interference is experienced, it may help to
install a second earth ground rod next to the plasma power supply. The plasma power supply chassis would
then be connected to this ground rod.
It is recommended that the Plasma Power Supply be within 20 - 30 ft (6.1 – 9.1 m) of the cutting table,
if possible.
7. The plasma control cable should be shielded with the shield connected only at the cutting machine end.
Connecting the shield at both ends will allow ground loop currents which may cause more interference than with
no shield at all.
Manual No. 0-4805 Auto-Cut 2003-10INSTALLATION
NOTE
C. Creating An Earth Ground
1. To create a solid, low resistance, earth ground, drive a 1/2 in (12 mm) or greater diameter copper clad ground
rod at least 6 - 8 ft (1.8 - 2.4 m) into the earth so that the rod contacts moist soil over most of its length.
Depending on location, a greater depth may be required to obtain a low resistance ground (see NOTE). Ground
rods, typically 10 ft (3.0 m) long, may be welded end to end for greater lengths. Locate the rod as close as
possible to the work table. Install a ground wire, 1/0 AWG (European 50 mm2) or greater, between the ground
rod and the star ground point on the cutting table.
NOTE
Ideally, a properly installed ground rod will have a resistance of three ohms or less.
To test for a proper earth ground, refer to the following diagram. Ideally, the reading on the multimeter should be
3 VAC for 115VAC line, or 1.5 VAC for 230 VAC line.
CAUTION
Remove all other connections from the ground rod during this test.
This test assumes the 115 or 230 VAC source neutral is connected to the utility earth ground.

Dangerous high voltage is present when the power supply is connected to input power. Do not connect input
power or operate the power supply unless the connections cover is fastened in place.
2. Increasing the ground rod length beyond 20 - 30 ft (6.1 – 9.1 m) does not generally increase the effectiveness
of the ground rod. A larger diameter rod which has more surface area may help. Sometimes keeping the soil
around the ground rod moist by continuously running a small amount of water into it will work. Adding salt to the
soil by soaking it in salt water may also reduce its resistance. When these methods are used, periodic
checking of the ground resistance is required to make sure the ground is still good.
Manual No. 0-4805 Auto-Cut 2003-11INSTALLATION
D. Routing Of Torch Leads
1. To minimize RF interference, position torch leads as far as possible from any CNC components, drive motors,
control cables, or primary power lines. If cables have to pass over torch leads, do so at an angle. Do not run the
plasma control or other control cables in parallel with the torch leads in power tracts.
2. Keep torch leads clean. Dirt and metal particles bleed off energy, which causes difficult starting and increased
chance of RF interference.
3.07 Connect Work Cable
1. Pass the end of the work cable upward through the leads bracket at the bottom of the power supply rear
panel, then up through the opening in the connections cover support panel.
2. Refer to the illustration. Connect the lead as shown. Tighten securely. Do not overtighten.
WARNINGS
Ensure that lead attachment hardware is properly sized. Excess length may cause damage if hardware contacts
other parts of the system.
The clear connections cover must remain in place.

Check for a solid and clean work cable connection to the workpiece or cutting table. The connection area must
be free from paint and rust.
E. Torch Connection
Check that the torch is properly connected.
F . Gas Supplies
Connect desired plasma and shield gases. Make sure gas sources meet requirements. Check connections and turn gas
supply on.
Select the desired shield gas as follows:
1. If gas shield is desired, set shield selector switch to GAS position.
2. If Water Mist shield is desired, set shield mode selector switch to ‘H2O MIST’ position. Water must be
connected to the control console at the shield water connection.
NOTES
T ap water should only be used for shield gas.
If tap water pressure is over 100 psi (6.9 bar) there must be a Water Regulator (Cat alog No. 8-6118)
installed between the water source and the Power Supply .
Manual No. 0-4805 Auto-Cut 2004-3OPERATION
H. Plasma Gas Purge
Move the Power Supply ON/OFF switch to the ON position.
An automatic gas purge will remove any condensation that may have accumulated in the torch and leads
while the system was shut down. After the purge is complete, if the RUN/SET switch is in SET position, gases
will flow.
I.Amperage Selection
Select the desired current output amperage.
J. Pressure and Flow Settings
1. Refer to the Torch manual for pressure and flow details according to the material being cut. Move the RUN/SET
switch to SET position. (Gas will flow through the torch). Set gas pressures and flows as follows:
2. To set the Plasma Gas pressure:
a. Pull out the knob on the Plasma Gas pressure control knob.
c. Turn the knob to adjust gas pressure.
d. Push the knob back in to lock the pressure setting.
3. To set the Shield Gas pressure: Set the Shield Mode Selector switch to the GAS or H

4.04 Cut Quality
Cut quality requirements differ depending on application. For instance, nitride build-up and bevel angle may be
major factors when the surface will be welded after cutting. Dross-free cutting is important when finish cut quality
is desired to avoid a secondary cleaning operation. Cut quality will vary on different materials and thicknesses.

T op-Edge Rounding
Rounding on the top edge of a cut due to wearing from the initial contact of the plasma arc on the workpiece.
Dross Build-up and T op Spatter
Dross is molten material which is not blown out of the cut area and re-solidifies on the plate. Top spatter is
dross which accumulates on the top surface of the workpiece. Excessive dross may require secondary cleanup operations after cutting.
Kerf Width
The width of material removed during the cut.
Nitride Build-up
Nitride deposits which may remain on the cut edge of the carbon steel when nitrogen is present in the plasma
gas stream. Nitride buildups may create difficulties if the steel is welded after the cutting process.
Manual No. 0-4805 Auto-Cut 2004-5OPERATION
Direction of Cut
The plasma gas stream swirls as it leaves the torch to maintain a smooth column of gas. This swirl effect results
in one side of a cut being more square than the other. Viewed along the direction of travel, the right side of the
cut is more square than the left.

Swirl Effect on Side Characteristics Of Cut
To make a square - edged cut along an inside diameter of a circle, the torch should move counterclockwise
around the circle. To keep the square edge along an outside diameter cut, the torch should travel in a clockwise
direction.
Underwater Cutting
Cutting on a water table either underwater or with the water touching the plate or with a water muffler system
is not recommended. If a water table is used the water level must be a minimum of 4 inches from the bottom of
the plate. Failure to follow this recommendation could result in poor cut quality and short consumable parts
life.
Ohmic Sensing
Ohmic height sensing is not recommended with water shield. Water on the plate interferes electrically with the
ohmic sensing circuit.

3. Check the AC lamp. If lamp is ON, AC input power is present in the power supply.
Circuitry in the power supply monitors the status of various conditions. If the circuitry detects a situation
requiring operator attention, the status lamp on the control panel flashes a 2-part code to indicate a code group
and then a particular condition within the group. After 4 seconds, the sequence repeats.
Example: Lamp flashes 4 times; the condition is in group 4. After a 1.2 second delay, the lamp blinks 3 times;
the status code is 4-3. After a 4-second delay, the lamp repeats the sequence until the condition is corrected.

Operational Suggestions
1. Wait five minutes before setting the ON/OFF switch to OFF after operation. This allows the cooling fan to run
to dissipate operating heat from the power supply.
2. For maximum parts life, do not operate the pilot arc any longer than necessary.
3. Use care in handling torch leads and protect them from damage.
4. When using water as the shield note the following:
• Use clean drinking quality tap water to help prevent particulate build-up within the system water shield
plumbing.
• Particulate contamination and bulid-up can cause reduced consumable parts life and premature torch
failure.
• A cartridge type particulate water filter may help achieve optimum cutting performance.

5.04 Coolant Replacement Procedure
Replace coolant as follows:
1. Disconnect the system from main input power. At the bottom of the coolant tank, disconnect the coolant line
fitting and collect coolant in a disposable container.
2. Connect the system to main input power and turn it on to allow the pump to empty the tank,. The pump
will run approximately for 20 seconds before the flow switch causes an interlock. This procedure may be
repeated a few times until the tank is completely empty.
3. Connect the coolant line fitting and fill the tank with fresh coolant until the right level is reached.
