What is plasma?
Plasma is a gas heated to an extremely high temperature and ionized so that it becomes
electrically conductive. Plasma arc cutting uses the plasma as an electrode to transfer a
electrical arc to the work piece. The heat of the arc melts the work piece and the force of the
plasma and shield gases blow away the molten metal to cut the work piece.
Different metals react differently to plasma cutting. Carbon steel can be oxidized, and is usually
cut with a plasma containing oxygen to take advantage of the exothermic process. Higher
levels of oxygen in the plasma result in higher heat and higher rates of oxidation. The result is
a faster and cleaner cut. Stainless steel and aluminum are not subject to rapid oxidation and
depend entirely on the plasma’s heat for the cutting process. Because plasma produces much
higher heat than the oxygen-fuel cutting process, plasma can cut stainless steel and aluminum
quickly and cleanly.
Choosing a plasma process
Thermal Dynamics systems offer a variety of plasma cutting processes for precision and general
purpose cutting. Ultra-Cut systems offer precision cutting as well as conventional cut options.
Auto-Cut O2 systems offer high speed oxygen cutting, precision non-ferrous and conventional
cut options. Auto-Cut systems offer conventional mild steel and precision non-ferrous options.

Consumable parts are specifically designed to perform in specific conditions. Using the
wrong consumable parts will result in short parts life and poor cut quality. Use the cut charts to
determine which consumable parts to use in any specific application.
Installing consumable parts
The XT torch is a precision instrument. Take care when installing consumable parts to keep the
parts clean and free from any contamination that might cause a gas or coolant leak inside the
consumable parts cartridge.
Assembly Sequence, 30-150 Amp Consumables
7.04 Torch Consumables Installation
Do not install consumables into the Cartridge
while the Cartridge is attached to the Torch Head.
Keep foreign materials out of the consumables and Cartridge.
Handle all parts carefully to avoid damage,
which may affect torch performance.
1. Install the consumables as follows:

To ensure proper assembly of the torch cartridge:
1. Place the cartridge assembly on a clean, flat surface
2. Assemble the consumable parts from electrode to shield cap.
3. Install the consumable parts in the cartridge
4. Install the shield retainer to complete the cartridge assebly.
page 5
Consumable Parts Life
Tips and electrodes wear under normal usage. Tips and electrodes should be
changed before failure to avoid damaging the other consumable parts or the material to be
cut. Optimum life will vary according to specific cutting conditions. Keep a count of cuts
per set of tip and electrode in a given application to establish the most effective time to
change consumable parts sets. The pilot arc is more erosive to the tip and electrode than
the cutting arc is, so an application that demands more pilot and pierce sequences will erode
consumable parts faster than an application that uses longer cuts but fewer arc starts.
Tip – Tips wear as the arc erodes the tip orifice. When the tip is no longer round or has
become enlarged, it should be replaced. Tip life is best when cuts are made at optimum
speed. Cutting too fast or too slow causes the arc to bend and biases erosion, resulting
in an orifice that is oval shaped.
Electrodes – The electrode wears from the hafnium or tungsten insert at the end of the
electrode. The face of the insert is liquefied by the heat of the arc and droplets erode from
the insert as cutting progresses. Proper gas flow will support longer electrode life.
An electrode should be replaced when the electrode insert is pitted to a depth of 1/16 inch
(see chart below).

Cut Surface – Cut surface is influenced by process and positioner precision more than by other
parameters. For smoothest cut face on different materials, use: mild steel – oxygen plasma
Direction of cut – The plasma has a clockwise swirl as it exits the torch tip. Considering the
direction of torch travel, the right side of the cut will always show less bevel and top edge
rounding than the left side. Program cuts so that the right side will be on the finished part and
the left side will be scrap.

Top edge rounding – Caused by the heat of the plasma arc at the top surface of the cut.
Proper torch height control can minimize or eliminate top edge rounding. Excessive top
edge rounding is often a sign that torch cutting height should be lower.
Top spatter – Top spatter is caused by fast cutting or by too high a torch height setting.
Reducing cut speed or lowering torch cutting height will reduce top spatter. Top spatter is
easy to remove.
Bottom dross – Molten metal may build up on the bottom of the plate. Faster cut speeds
reduce bottom dross as less material is melted. Bottom dross that is easy to remove is an
indication of slow cutting speed. Bottom dross that is difficult to remove or requires grinding
is an indication of too fast cut speed.
page 7
Kerf – Kerf width is specified in the cut charts and can be calculated into cut programs.
The kerf width is related to tip orifice size and higher current cutting will produce a wider kerf.
Higher torch height will also result in a wider kerf.
Bevel angle – Precision cut processes produce bevel angle in the 0-3° range. Conventional
plasma cutting will produce larger bevel angles. Proper torch height control will produce the
smallest bevel angle, as well as improved kerf width and minimal top edge rounding. A slower
cut speed can be used when cutting circles and corners to reduce bevel.

Nitride contamination – Air plasma cutting will produce nitride contamination of the cut face
on carbon steel and stainless steel. Nitride contaminated surfaces will require grinding before
welding to eliminate weld porosity. The depth of the contamination will be close to the Heat
Affected Zone, between .005 and .010” in depth.
Nitride contamination can be eliminated by using a process other than air plasma;
oxygen plasma for carbon steel, H35 or nitrogen/WMS for non-ferrous materials.
Cut speed – Cut charts specify a cut speed that will produce high quality cut performance.
Any plasma system can cut at faster or slower speeds, but cut performance will be affected.
Cut speed should be reduced for corners and tight curves to reduce bevel and corner rounding.
Optimum cut speeds produce a trailing arc which will be visible in the slight arc lines
visible in the cut face. Arc lines are useful for evaluating cut speed on mild steel, but less so
for aluminum and stainless steel. Arc lines that trail at less than 15° indicate that cut speed is
in the optimum range when air or oxygen plasma processes are used. Optimum cut quality in
precision cutting processes will result in arc lines that are near vertical. A slow cut speed may
show arc lines that angle forward and a fast cut speed will show arc lines at a sharper angle
relative to the top of the plate.

Piercing
Lead-out
Overcut
Corner
Pierce
Lead-in
Piercing causes the molten metal to form a puddle on top of the plate. On thicker plate,
pierce height is calculated to keep the torch away from the plate so that the molten metal does
not adhere to the consumable parts and shorten parts life. Hold pierce height as the cutting
table starts movement to allow the torch to clear the pierce puddle before moving to cut height.
Using the Inova height controller, this is done using the Set Pierce Time function on the edit
screen.
Lead-in and lead-out
Lead-in and lead-out should be calculated to allow the torch to move to cut height
before starting the final piece contour of the cut and to move away from the final piece before
beginning end of cut current ramp down.
Corners
The cutting arc normally trails the torch tip orifice. When the torch makes an abrupt
change in direction this trailing arc cannot change direction as quickly at the bottom of the cut
as at the top of the cut. This results in undercutting of sharp corners. 2 techniques can be used
to minimize this effect.
1. Use cut-outs – Overcut past the corner of the shape, then return and cross over the cut line to
achieve a square corner. Triangular or looped overcuts are commonly used.
2. Use the CNC corner slowdown function to hold torch height as it enters and leaves
the corner. As the speed decreases, the arc voltage will increase, driving the torch
down, so corner slowdown will lock out the height controller during the corner cut,
keeping the torch at the programmed height, regardless of arc voltage variations.
page 13
Cutting Circles
Pierce
Lead-in
Overrun
at end
of cut
Circle cutting demands precise motion control and circle cut quality will vary as the circle
diameter approaches the thickness of the plate. In general, a circle that is equal in diameter
to the thickness of the plate being cut is the minimum circle diameter possible. Cut quality will
decrease markedly when the circle diameter is less than 1.5 times the thickness of the plate
being cut.
For maximum circle cut quality:
1. Slow down cut speed. Smaller circles may require a cut speed that is 60-50% of the
speed specified in system cut charts. A slower cut speed will eliminate trailing arc and allow the
arc to cut at closer to 0° of bevel.
2. Maintain constant cut height through the circle. This may require locking out the height
controller. As the cut speed slows, arc voltage increases and the height controller tends to drive
the torch down, changing cut bevel. Avoid torch height movement by locking out the height
controller during the circle cut.
3. Start the cut in the center of the circle and use a 90° lead-in to the circle. When the
positioner is in top running condition, a 90° lead-in will produce less distortion at the circle
initiation. A cutting table with backlash may produce a better cut when a radial lead-in is used.
4. End the cut by overburning the circle cut line rather than by using a lead-out. Time the
cut to end just as the arc completes the circle. A lead out or too much of an overburn will cause
the arc to cut more of the outside of the circle and cause a distortion at the point where the
circle cut is completed. Many CNC systems use and advanced off feature to ramp down cutting
current end of cut. Use of the CNC’s advanced off feature will improve circle cutting.

N2/Water Mist Secondary
In this process, tap water is used instead of a shield gas. The water is vaporized as
it passes through the torch head and a portion of the molecules separate onto hydrogen and
oxygen. This vapor protects the cut surface from ambient air contamination and eliminates
nitriding in the cut surface.
Cutting with the N2/WMS process is economically efficient and produces genuine
precision cut quality over a broad range of non-ferrous applications.
Considerations:
• Water supply should be at least 55 psi.
• Hard water will leave mineral deposits, just as it does in sinks and faucets. A standard
water softening filter will prevent mineral deposits that can interfere with water flow in the
torch passages.
• Ohmic sensing to establish initial torch height is ineffective when water is present.
The ohmic clip should be removed from the torch for N2/WMS cutting. The ohmic sensing
system will sense the level of any water on the plate rather than the true position of the plate.
®™
Underwater Cutting
Cutting under water is used by some operators to capture smoke and reduce flash and noise.
Cutting under water is possible with Ultra-Cut and Auto-Cut systems.
Considerations:
• Cutting under water will reduce cut capacity and speed by up to 30%
• The cooling effect of water on the bottom of the plate will facilitate formation of dross
• Cutting aluminum under or over water releases hydrogen, which can explode
• Cutting with N2/WMS process is not recommended
• The water in the table will become contaminated with cut residue and can be a toxic waste

Status Indicator
Auto-Cut and Ultra-Cut systems display system status codes that are useful for
optimizing system performance and for troubleshooting. The status code is displayed on
the power supply front panel.
AC Power Indicator:
Indicates AC power is being supplied to the system when the
ON/OFF switch is in ON position. When switch is first set to
ON, the indicator will blink, indicating gas purge at power on.
TEMP Indicator:
Normally OFF. Indicator will come ON when the internal
temperature sensors detect temperatures above normal limits.
Let the unit cool before continuing operation.
GAS Indicator:
Normally ON. Indicates adequate gas pressure for
operation in the system.
Status Indicator:
DC Indicator:
Indicates the power supply is generating output DC voltage.
Show system status. The number of flashes indicates the
status.
Refer to the Status Code Section for details. On power supply start-up, the indicator
flashes to show the revision level of the operating software installed in the system.
page 16
The Status Indicator flashes a 2 part code that indicates the status of the system.
When the Status Indicator is dark the system is ready to cut. It is normal for the Status Indicator
to flash when the GCM mode switch is placed in set mode. At system start up, the Status
Indicator flashes a 2 part code to indicate the CCM firmware version that is loaded into the
system. This code appears only once at start up. During normal operation the Status Indicator
may flash a code indicating an error or a condition that should be corrected. Some codes will
cause the system to cease operation to prevent damage to the hardware. Other codes will not
cause the system to cease operation, but will continue until the condition which caused the code
to initiate is changed.
Status codes appear in a 2 part sequence. The Status Indicator will flash a number of
times to indicate the first number in the code sequence, then pause for 1.2 seconds and flash
the second number of the code. After 4 seconds, the code sequence will repeat.
Example: The Status Indicator blinks 4 times, pauses, then blinks 3 times.
This code (4-3) indicates overheating coolant and will continue until the condition is corrected.

Lubricate Torch Cartridge O-Rings
Lubricate all three O-Rings on the Cartridge Assembly and all three O-Rings on the Torch
Head periodically with O-Ring Lubricant supplied. Remove the snap ring on the cartridge
assembly and slide the locking ring downward for access to the O-Ring under the locking ring.
Use only Thermal Dynamics No. 9-4893 O-Ring Oxygen Compatable Lubricant (Christo Lube MCG-129)
with this torch part. Use of other lubricants may cause irreparable damage to the torch.
An O-ring replacement kit with both torch and cartridge rings is available, catalog number 9-9488.
Coolant
Torch coolant becomes conductive with use and eventually will cause a shorted torch
condition. Torch coolant should be replaced every six months. Also remove and clean the
external coolant filter and the smaller filter located near the flow sensor.
Torch coolant is available pre-mixed or as concentrate.
