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
workpiece. 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.
Compliance Information EMC-1
7/10
ELECTROMAGNETIC COMPATIBILITY
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.
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.
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 Equip ment, Part 9:
Installation and Use.
Screening and shielding
Equipotential bonding
Bonding of all metallic components in the cutting
installation and adjacent to it should be considered.
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.
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.

Safety information
Before you set up and operate your Hypertherm system, read the separate Safety and Compliance Manual included
with your system for important safety information.
System description
The Powermax65 and Powermax85 are highly portable, 65-amp and 85-amp, handheld and mechanized plasma cutting
systems appropriate for a wide range of applications. The Powermax systems use air or nitrogen to cut electrically
conductive metals, such as mild steel, stainless steel, or aluminum. Smart Sense™ technology automatically adjusts the
gas pressure according to cutting mode and torch lead length for optimum cutting.
The Powermax65 can cut thicknesses up to 1 inch (25 mm) with a handheld torch and pierce thicknesses up to 5/8
inch (16 mm). The Powermax85 can cut thicknesses up to 1-1/4 inches (32 mm) and pierce thicknesses up to 3/4 inch
(19 mm). FastConnect™ provides a simple push-button torch connection to the power supply for quick torch changes.
The typical handheld Powermax system includes a Duramax™ series H65 or H85 hand torch with a complete set of the
consumables needed for cutting (shield, retaining cap, nozzle, electrode, swirl ring), a consumables box (containing
2 spare electrodes, 2 spare nozzles, 1 gouging nozzle, and 1 gouging shield), and a work cable. Reference materials
include: operator manual, quick setup card, registration card, setup DVD, and safety manual.
The typical mechanized Powermax system includes a Duramax series M65 or M85 machine torch with a complete set of
the consumables needed for cutting (shield, retaining cap, nozzle, electrode, swirl ring), a consumables box (containing
2 spare electrodes and 2 spare nozzles), work cable, and remote-start pendant. Reference materials include: operator
manual, quick setup card, registration card, setup DVD, and safety manual.
You can order additional styles of torches, consumables, and accessories – such as the plasma cutting guide – from
any Hypertherm distributor. See Section 6, Parts for a list of spare and optional parts.
Powermax65 and Powermax85 power supplies are shipped without a plug on the power cord. See Section 2 Power
Supply Setup for more information.

POWER SUPPLY SETUP
Position the power supply
Locate the power supply near an appropriate power receptacle for your installation: 200–480 volts (CSA 1-phase),
200–600 volts (CSA 3-phase), or 380/400 volts (3-phase CE). The power supply has a 10-foot (3 m) power cord.
Allow at least 10 inches (0.25 m) of space around the power supply for proper ventilation.
The power supply is not suitable for use in rain or snow.
To avoid toppling, do not set the power supply on an incline greater than 10 degrees.
Prepare the electrical power
Hypertherm (designated HYP on the data plate) input current ratings are used to determine conductor sizes for power
connection and installation instructions. The HYP rating is determined under maximum normal operating conditions and
the higher HYP input current value should be used for installation purposes.
The maximum output voltage will vary based on your input voltage and the circuit’s amperage. Because the current draw
varies during startup, slow-blow fuses are recommended as shown in the charts below. Slow-blow fuses can withstand
currents up to 10 times the rated value for short periods of time.
Caution: Protect the circuit with appropriately sized time-delay (slow-blow) fuses and a
line-disconnect switch.
2-4 powermax
65/85
Service Manual
POWER SUPPLY SETUP
Install a line-disconnect switch
Use a line-disconnect switch for each power supply so that the operator can turn off the incoming power quickly in an
emergency. Locate the switch so that it is easily accessible to the operator. Installation must be performed by a licensed
electrician according to national and local codes. The interrupt level of the switch must equal or exceed the continuous
rating of the fuses. In addition, the switch should:
• Isolate the electrical equipment and disconnect all live conductors from the incoming supply voltage when in the
OFF position.
• Have one OFF and one ON position that are clearly marked with O (OFF) and I (ON).
• Have an external operating handle that can be locked in the OFF position.
• Contain a power-operated mechanism that serves as an emergency stop.
• Have appropriate slow-blow fuses installed. See 2-6 Power connection for the Powermax65 or 2-8 Power
connection for the Powermax85 for recommended fuse sizes.
Requirements for grounding
To ensure personal safety, proper operation, and to reduce electromagnetic interference (EMI), the power supply must
be properly grounded.
• The power supply must be grounded through the power cord according to national and local electrical codes.
• Single-phase service must be of the 3-wire type with a green or green/yellow wire for the protective earth
ground and must comply with national and local requirements. Do not use a 2-wire service.
• Three-phase service must be of the 4-wire type with a green or green/yellow wire for protective earth ground
and must comply with national and local requirements.
• Refer to the separate Safety and Compliance Manual included with your system for more information on
grounding.

POWER SUPPLY SETUP
Prepare the gas supply
The gas supply can be shop-compressed or cylinder-compressed. A high-pressure regulator must be used on either
type of supply and must be capable of delivering gas to the air inlet on the power supply.
If the supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases, and
the life of the consumables shortens. For optimal performance, the gas should be compliant with ISO8573-1:2010,
Class 1.2.2 (that is, it should have a maximum number of solid particulate per m3 of <20,000 for particle sizes in the
range of 0.1-0.5 microns, <400 for particle sizes in the range of 0.5-1 microns, and <10 for particle sizes in the range
of 1-5 microns). The maximum water vapor dew point should be <-40° C (-40° F). The maximum oil (aerosol, liquid, and
vapor) content should be less than 0.1 mg/m3.
Additional gas filtration
When site conditions introduce moisture, oil, or other contaminants into the gas line, use a 3-stage coalescing filtration
system, such as the Eliminizer filter kit (part number 128647) available from Hypertherm distributors. A 3-stage filtering
system works as shown below toclean contaminants from the gas supply.
Water and particle filter
Gas supply
The filtering system should be installed between the gas supply and the power supply. Additional gas filtration may
increase the required minimum inlet pressure.

1/4NPT quick-disconnect coupler, or a 1/4 NPT x G-1/4 BSPP (CE units) quick-disconnect coupler.
The recommended inlet pressure while gas
is flowing is 85 - 135 psi (5.9 - 9.3 bar).

Introduction
Duramax™ series handheld and machine torches are available for the Powermax65 and Powermax85 systems. The
FastConnectTM 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.
This section explains how to set up your torch and choose the appropriate consumables for the job.
Consumable life
How often you need to change the consumables on your Powermax65 or Powermax85 will depend on a number of
factors:
• The thickness of the metal being cut.
• The average length of the cut.
• Whether you are doing machine or hand cutting.
• 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.
Under normal conditions, the electrode will wear out first during machine cutting and the nozzle will wear out first when
hand cutting.
A general rule is that a set of consumables lasts approximately 2 to 3 hours of actual “arc on” time for hand cutting,
depending on these factors. For mechanized cutting, consumables should last about 3 to 5 hours.
You will find more information about proper cutting techniques in Section 4, Operation.

Choose the hand torch consumables
Powermax systems with the Duramax series H65, H85, H65s, or H85s torch are shipped with a full set of cutting
consumables pre-installed. Hypertherm also includes spare cutting electrodes and nozzles, and gouging consumables in
the consumables box.
Both styles of hand torches shown above use the same consumables.
Hand torches use shielded consumables. Therefore, you can drag the torch tip along the metal.
Consumables for hand cutting are shown on the next page. Notice that the retaining cap and electrode are the same for
cutting, gouging, and FineCut® applications. Only the shield, nozzle, and swirl ring are different.
For the best cut quality on thin materials, you may prefer to use FineCut consumables, or use a 45A nozzle and reduce
the amperage to that setting.

electrode, and swirl ring.
With the power switch in the OFF (O) position, install the machine torch consumables in a manner similar to the hand
torch consumables. Refer to 3-6 Install the hand torch consumables.
Aligning the torch
Mount the machine torch perpendicular to the workpiece in order to get a vertical cut. Use a square to align the torch at
0° and 90°.

TORCH SETUP
Connecting an optional machine interface cable
The Powermax65 and Powermax85 power supplies are equipped with an optional, factory-installed, five-position voltage
divider that is designed to be safely connected without tools. The built-in voltage divider provides a scaled down arc
voltage of 20:1, 21.1:1, 30:1, 40:1, and 50:1 (maximum output of 18V). An optional receptacle on the rear of the power
supply provides access to the scaled down arc voltage and signals for arc transfer and plasma start.
Note: The factory presets the voltage divider to 50:1. To change the voltage divider to a different setting, refer to 3-20
Setting the five-position voltage divider.
Caution: The factory-installed internal voltage divider provides a maximum of
18 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 for the Powermax65 and Powermax85:
• 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 (25 ft, 7.6 m) or 228351 (50 ft, 15 m) for wires terminated with spade
connectors.
- Use part number 123896 (50 ft, 15 m) for a cable terminated with a D-sub connector. (Compatible with
Hypertherm’s Edge Ti and Sensor PHC products.)
• To use signals for arc transfer and plasma start only, use either part number 023206
(25 ft, 7.6 m) or part number 023279 (50 ft, 15 m). These cables have spade connectors as shown below.

TORCH SETUP
Note: The cover on the machine interface receptacle prevents dust and moisture from damaging the receptacle
when not in use. This cover should be replaced if damaged or lost (part number 127204).
See Section 6, Parts 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 listed and certified torch height controllers or CNC controllers 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.
Note: 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 the figure
below. The table provides details about each signal type.

Using the cut charts
The following sections provide cut charts for each set of mechanized consumables. 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) — 80% of the maximum speed ratings. These speeds result in the
greatest number of cut parts, but not necessarily the best possible cut quality.
Note: The arc voltage increases as the consumables wear and the voltage setting should be increased to
maintain the correct Torch-to-Work Distance.
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.
Note: Hypertherm collected the data under laboratory test conditions using new consumables.
