Electromagnetic Compatibility (EMC)
Introduction
Hypertherm’s CE-marked equipment is built in compliance
with standard EN60974-10. The equipment should be
installed and used in accordance with the information
below to achieve electromagnetic compatibility.
The limits required by EN60974-10 may not be adequate
to completely eliminate interference when the affected
equipment is in close proximity or has a high degree of
sensitivity. In such cases it may be necessary to use other
measures to further reduce interference.
This cutting equipment is designed for use only in an
industrial environment.
Installation and use
The user is responsible for installing and using the plasma
equipment according to the manufacturer’s instructions.
If electromagnetic disturbances are detected then it shall
be the responsibility of the user to resolve the situation
with the technical assistance of the manufacturer. In some
cases this remedial action may be as simple as earthing
the cutting circuit, see Earthing of the work piece. In other
cases, it could involve constructing an electromagnetic
screen enclosing the power source and the work
complete with associated input filters. In all cases,
electromagnetic disturbances must be reduced to the
point where they are no longer troublesome.
Assessment of area
Before installing the equipment, the user shall make an
assessment of potential electromagnetic problems in the
surrounding area. The following shall be taken into
account:
a. Other supply cables, control cables, signaling
and telephone cables; above, below and adjacent
to the cutting equipment.
b. Radio and television transmitters and receivers.
c. Computer and other control equipment.
d. Safety critical equipment, for example guarding of
industrial equipment.
e. Health of the people around, for example the use
of pacemakers and hearing aids.
f. Equipment used for calibration or measurement.
g. Immunity of other equipment in the environment.
User shall ensure that other equipment being
used in the environment is compatible. This may
require additional protection measures.
h. Time of day that cutting or other activities are to
be carried out.
The size of the surrounding area to be considered will
depend on the structure of the building and other activities
that are taking place. The surrounding area may extend
beyond the boundaries of the premises.
Methods of reducing emissions
Mains supply
Cutting equipment must be connected to the mains
supply according to the manufacturer’s recommendations.
If interference occurs, it may be necessary to take
additional precautions such as filtering of the mains
supply.
Consideration should be given to shielding the supply
cable of permanently installed cutting equipment, in
metallic conduit or equivalent. Shielding should be
electrically continuous throughout its length. The shielding
should be connected to the cutting mains supply so that
good electrical contact is maintained between the conduit
and the cutting power source enclosure.
Safety and Compliance SC-11
Electromagnetic Compatibility (EMC)
Maintenance of cutting equipment
The cutting equipment must be routinely maintained
according to the manufacturer’s recommendations. All
access and service doors and covers should be closed
and properly fastened when the cutting equipment is in
operation. The cutting equipment should not be modified
in any way, except as set forth in and in accordance with
the manufacturer’s written instructions. For example, the
spark gaps of arc striking and stabilizing devices should
be adjusted and maintained according to the
manufacturer’s recommendations.
Cutting cables
The cutting cables should be kept as short as possible
and should be positioned close together, running at or
close to the floor level.
Equipotential bonding
Bonding of all metallic components in the cutting
installation and adjacent to it should be considered.
Earthing of the workpiece
Where the workpiece is not bonded to earth for electrical
safety, nor connected to earth because of its size and
position, for example, ship’s hull or building steel work, a
connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be
taken to prevent the earthing of the workpiece increasing
the risk of injury to users, or damage to other electrical
equipment. Where necessary, the connection of the
workpiece to earth should be made by a direct connection
to the workpiece, but in some countries where direct
connection is not permitted, the bonding should be
achieved by suitable capacitances selected according to
national regulations.
Note: The cutting circuit may or may not be earthed for
safety reasons. Changing the earthing arrangements
should only be authorized by a person who is competent
to assess whether the changes will in crease the risk of
injury, for example, by allowing parallel cutting current
return paths which may damage the earth circuits of other
equipment. Further guidance is provided in IEC 60974-9,
Arc Welding Equipment, Part 9: Installation and Use.
However, metallic components bonded to the workpiece
will increase the risk that the operator could receive a
shock by touching these metallic components and the
electrode (nozzle for laser heads) at the same time.
The operator should be insulated from all such bonded
metallic components.
Screening and shielding
Selective screening and shielding of other cables and
equipment in the surrounding area may alleviate problems
of interference. Screening of the entire plasma cutting
installation may be considered for special applications.

Introduction
The Duramax robotic torch line consists of 3 torches: 180°, 90°, and 45°, designed for use with the Powermax65®,
Powermax85, and Powermax105 systems. The Duramax robotic torches are not compatible with the Powermax125
system. These torches use only Duramax consumables.
The Duramax Hyamp robotic torch line also consists of 3 torches: 180°, 90°, and 45°, designed for use with the
Powermax65, Powermax85, Powermax105, and Powermax125 systems. These torches use only Duramax Hyamp
consumables.
Both lines of torches are designed for use in robotic applications. They can also be used in other mechanized
applications where careful positioning of the torch and the ability to approach the workpiece at an angle are important
considerations.
The FastConnect™ quick-disconnect system makes it easy to remove the torch for transport or to switch from one torch
to the other if your applications require the use of different torches. The torches are cooled by ambient air and do not
require special cooling procedures.
Duramax and Duramax Hyamp robotic torches comply with IEC 60974-7 and are not suitable for use in the rain or snow.

Install the torch
Depending on the type of torch, robot, and installation method, you may need to disassemble the FastConnect plug or
torch to install the torch. For the outside mounting method, it is not necessary to disassemble the torch. The torch can be
mounted per the instructions in Mount the torch on page 30.
For the through-arm mounting method, see Figure 3 to determine if the robot’s through-arm cavity is large enough to
accept the torch lead’s FastConnect plug as assembled or with the 2 shells removed. If the through-arm cavity is large
enough for the FastConnect plug as assembled, route the torch lead through the through-arm cavity. Then, mount the
torch to the robot arm per the instructions in Mount the torch on page 30.
Figure 3

If the through-arm cavity is large enough for the disassembled FastConnect plug (see Figure 3 for dimensions), complete
the following instructions.
1. Remove the mounting screws from the bottom shell and pull the 2 shells apart.
The red disconnect button and tab on top of the FastConnect plug are spring loaded and
self-adjust below the surface of the plug while being routed through the through-arm
cavity.
2. Cover the end of the FastConnect plug with tape to keep dirt and other contaminants from getting into the gas line.
3. Route the torch lead through the through-arm cavity.
4. Install the 2 shells by aligning them over the torch lead, making sure the strain relief is held in place by the slot in the
FastConnect shells.
5. Tighten the mounting screws.
6. Mount the torch to the robot arm per the instructions in Mount the torch on page 30.
Disassemble the robotic torch
If the through-arm cavity is not large enough to accept the FastConnect plug at all (see Figure 3 for dimensions),
complete the following instructions to disassemble, install, and reassemble the torch.
WARNING!
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
The maintenance procedures in this section must be performed by a qualified

Consumable life
How often you need to change the consumables on your torch will depend on a number of factors:
The thickness of the metal being cut.
The average length of cut.
The air quality (presence of oil, moisture, or other contaminants).
Whether you are piercing the metal or starting cuts from the edge.
Proper torch-to-work distance when gouging or cutting with unshielded consumables.
Proper pierce height.
Whether you are cutting in “continuous pilot arc” mode or normal mode. Cutting with a continuous pilot arc causes
more consumable wear.
You will find more information about proper cutting techniques in Operation on page 47.

Choosing the consumables
Duramax robotic torches
Duramax robotic torches are shipped with a consumable kit that includes enough consumables to create a complete
consumable set for 65, 85, or 105 amperage shielded cutting. An ohmic-sensing retaining cap is available for use with
shielded consumables, a deflector is available for unshielded cutting and FineCut
fine-featured cutting on thin materials. All 3 styles of Duramax robotic torches use the same consumables.
With unshielded consumables, you must keep the torch a small distance, about 2.0 mm (0.08 inch), away
from the workpiece. Unshielded consumables generally have a shorter life than shielded consumables.

2 – Torch Setup
Connecting the machine interface cable
The power supply may be equipped with a five-position voltage divider board. The built-in voltage divider provides a
scaled down arc voltage of 20:1, 21.1:1, 30:1, 40:1, or 50:1 (maximum output of 16 V). A receptacle on the rear of the
power supply (see Figure 17) provides access to the scaled down arc voltage and signals for arc transfer and plasma
start.
The factory presets the voltage divider to 50:1. To change the voltage divider to a different
setting, see Setting the five-position voltage divider on page 44.
CAUTION!
The factory-installed internal voltage divider provides a maximum of 16 V under open circuit
conditions. This is an impedance-protected functional extra low voltage (ELV) output to prevent
shock, energy, and fire under normal conditions at the machine interface receptacle and under single
fault conditions with the machine interface wiring. The voltage divider is not fault tolerant, and ELV
outputs do not comply with safety extra low voltage (SELV) requirements for direct connection to
computer products.
Hypertherm offers several choices of machine interface cables:
To use the built-in voltage divider that provides a scaled down arc voltage in addition to signals for arc transfer and
plasma start:
Use part number 228350 (7.6 m, 25 feet) or 228351 (15 m, 50 feet) for wires terminated with spade
connectors.
Use one of the following part numbers for a cable terminated with a D-sub connector. (Compatible with
Hypertherm products, such as EDGE
223354 (3.0 m, 10 feet)
223355 (6.1 m, 20 feet)
223048 (7.6 m, 25 feet)
223356 (10.7 m, 35 feet)

Refer to Machine interface pinout on page 43 for receptacle pinout information.
The cover on the machine interface receptacle prevents dust and moisture from damaging
the receptacle when not in use. This cover (127204) should be replaced if damaged or
lost.
Refer to Maintenance and Parts on page 65 for more information.
Installation of the machine interface cable must be performed by a qualified service technician. To install a machine
interface cable:
1. Turn OFF the power and disconnect the power cord.
2. Remove the machine interface receptacle’s cover from the rear of the power supply.
3. Connect the Hypertherm machine interface cable to the power supply.
4. If you are using a cable with a D-sub connector on the other end, plug it into the appropriate pin connector on the
torch height controller or CNC. Secure it with the screws on the D-sub connector.
If you are using a cable with wires and spade connectors on the other end, terminate the machine interface cable
inside the electrical enclosure of the torch height controller or CNC controller to prevent unauthorized access to the
connections after installation. Verify that the connections are correct and that all live parts are enclosed and
protected before operating the equipment.
The integration of Hypertherm equipment and customer-supplied equipment including
interconnecting cords and cables, if not listed and certified as a system, is subject to
inspection by local authorities at the final installation site.
The connector sockets for each type of signal available through the machine interface cable are shown in Figure 18.

Using the cut charts
The cut charts for each set of mechanized consumables can be found in the Tor ch Set up section of the Operator Manual
that shipped with the system. The manuals also can be downloaded from Hypertherm’s website (www.hypertherm.com
using the “Downloads library” link. A consumable diagram with part numbers precedes each set of charts. For each
consumable type, there are Metric and English charts for mild steel, stainless steel, and aluminum.
Each chart contains the following information:
Material Thickness – Thickness of the workpiece (metal plate being cut).
Torch-to-Work Distance – For shielded consumables, the distance between the shield and the workpiece during
cutting. For unshielded consumables, the distance between the nozzle and the workpiece during cutting.
Initial Pierce Height – Distance between the shield (shielded) or the nozzle (unshielded) and the workpiece when
the torch is triggered, prior to descending to the cut height.
Pierce Delay Time – Length of time the triggered torch remains stationary at the pierce height before the torch
starts the cutting motion.
Best Quality Settings (cut speed and voltage) – Settings that provide the starting point for finding the best cut
quality (best angle, least dross, best cut-surface finish). Adjust the speed for your application and table to obtain the
desired result.
)
Production Settings (cut speed and voltage) – 70% to 80% of the maximum speed ratings. These speeds result in
the greatest number of cut parts, but not necessarily the best possible cut quality.
The arc voltage increases as the consumables wear, so the voltage setting may need to
be increased to maintain the correct torch-to-work distance. Some CNCs monitor the arc
voltage and adjust the torch lifter automatically.
Each cut chart lists hot and cold air flow rates.
Hot air flow rate – Plasma is on, the system is operating at running current, and the system is in a steady state at
the default system pressure (automatic mode).
Cold air flow rate – Plasma is off and the system is in a steady state with air flowing through the torch at the default
system pressure.
Hypertherm collected the cut chart data under laboratory test conditions using new
consumables.

A robotic torch teach tool (229456) for only the Duramax robotic torches is available from Hypertherm to assist with
programming the robot before cutting. The torch teach tool enables the system operator to program the robot’s cutting
path, while visually verifying the torch will not touch the workpiece while cutting. Contact with the workpiece while cutting
can damage the shield and nozzle and affect the cut surface. The torch teach tool is equipped with a spring-loaded tip to
allow for variations in consumable lengths and stand-off distances.
To install the torch teach tool:
1. Tur n O FF (O) the power.
2. Remove the consumables from the torch.
3. Thread the torch teach tool onto the end of the torch
in place of the consumables.
As a safety feature, the torch teach tool does not engage
the cap-sensor switch. This will cause a cap-sensor fault
code to be generated when the system is turned ON,
thereby disabling the torch from firing while in teach
mode.
After programming the robot:
1. Tur n O FF (O) the power.
2. Remove the torch teach tool.
3. Install the consumables.

3–Operation
Negative cut angle
Square cut
Positive cut angle
Problem Cause
The torch is too low.
The torch is too high.
Solution
Raise the torch; or if you are using a torch height
control, increase the arc voltage.
Lower the torch; or if you are using a torch height
control, decrease the arc voltage.
Understand and optimize cut quality
Several factors affect cut quality:
Cut angle – The degree of angularity of the cut edge.
Dross – The molten material that solidifies on the top or bottom of the workpiece.
Straightness of the cut surface – The cut surface can be concave or convex.
The following topics explain how these factors can affect cut quality.
Cut or bevel angle
A positive cut angle results when more material is removed from the top of the cut than from the bottom.
A negative cut angle results when more material is removed from the bottom of the cut.
Figure 20 – Cut angles
The squarest cut angle will be on the right side with respect to the forward motion of the
torch. The left side will always have some degree of cut angle.
To determine whether a cut-angle problem is being caused by the plasma system or the drive system, make a test cut and
measure the angle of each side. Next, turn the torch 90° in its holder and repeat the process. If the angles are the same in
both tests, the problem is in the drive system.
If a cut-angle problem persists after mechanical causes have been eliminated, check the torch-to-work distance,
especially if the cut angles are all positive or all negative. Also consider the material being cut: if the metal is magnetized
or hardened, you are more likely to experience cut angle problems.
Dross
Some amount of dross will always be present when cutting with air plasma. However, you can minimize the amount and
type of dross by adjusting your system correctly for your application.
Excess dross appears on the top edge of both pieces of the plate when the torch is too low (or voltage is too low when
using a torch height control). Adjust the torch or adjust the voltage in small increments (5 volts or less) until the dross is
reduced.
Duramax/Duramax Hyamp Robotic Torches Service Manual 807460 49
3 – Operation
Low-speed dross forms when the torch’s cutting speed is too slow and the arc angles ahead. It forms as a heavy, bubbly
deposit at the bottom of the cut and can be removed easily. Increase the speed to reduce this type of dross.
High-speed dross forms when the cutting speed is too fast and the arc angles behind. It forms as a thin, linear bead of
solid metal attached very close to the cut. It is more firmly attached to the bottom of the cut than at low speed and is
difficult to remove. To reduce high-speed dross:
Decrease the cutting speed.
Decrease the torch-to-work distance.
Straightness of the cut surface
A typical plasma cut surface is slightly concave.
The cut surface may become more concave, or convex. Correct torch height is required to keep the cut
surface acceptably close to straight. Worn consumables also affect the straightness of the cut.
A strongly concave cut surface occurs when the torch-to-work distance is too low. Increase the
torch-to-work distance to straighten the cut surface.
A convex cut surface occurs when the torch-to-work distance is too great or the cutting current is too
high. First, try lowering the torch, then reduce the cutting current.
Piercing a workpiece using the robotic torch
As with the hand torch and machine torch, you can start a cut with the robotic torch at the edge of the workpiece or by
piercing the workpiece. Piercing may result in a shorter consumable life than with edge starts.
The cut charts, provided in the system’s Operator Manual, include a column for the recommended torch height when
starting a pierce. For the Powermax65, Powermax85, and Powermax105, the pierce height is generally 2.5 times the
cutting height. For the Powermax125, the pierce height is generally between 1.5 and 4 times the cut height. Refer to the
cut charts for specific values.
The pierce delay must be long enough that the arc can pierce the material before the torch moves, but not so long that
the arc “wanders” while trying to find the edge of a large hole. As consumables wear, this delay time may need to be
increased. Pierce delay times given in the cut charts are based on average delay times throughout the life of the
consumables.
When piercing materials close to the maximum thickness for a specific process, consider the following important factors:
Allow a lead-in distance approximately equal to the thickness of the material being pierced. For example, 20 mm
(0.75 inch) material requires a 20 mm lead-in.
To avoid damage to the shield from the buildup of molten material created by the pierce, do not allow the torch to
descend to cut height until it has cleared the puddle of molten material.
Different material chemistries can have an adverse effect on the pierce capability of the system. In particular,
high-strength steel with a high manganese or silicon content can reduce the maximum pierce capability. Hypertherm
calculates mild steel parameters with certified A-36 plate.
Using a “flying pierce” (that is, starting torch motion immediately after transfer and during the pierce process) can
extend the piercing capability of the system in some cases. Because this can be a complex process that can damage
the torch or other components, a stationary or edge start is recommended.

Duramax/Duramax Hyamp Robotic Torches Service Manual 807460 51
3 – Operation
The torch is fired into the air (beginning or ending the cut off of the plate surface). Starting at the edge is acceptable
as long as the arc makes contact with the workpiece when started.
A pierce is started with an incorrect torch height. See the cut charts in the Tor ch Setu p section of the system’s
Operator Manual for the specific initial pierce height.
The pierce time is incorrect.
The air quality is poor (oil or water in the air).
There might be a faulty pilot arc IGBT, which can shorten nozzle life.
The swirl ring or retaining cap is worn and needs to be replaced.
