Preventive maintenance overview
Congratulations on the purchase of your Hypertherm MAXPRO200 plasma system.
Hypertherm designs its plasma systems to withstand the demands of rugged industrial environments for many years of
service. To maintain optimal system performance, minimize overall operating costs, and prolong system life, regular
preventive maintenance practices must be followed. When properly maintained, your Hypertherm plasma system will
serve you for many years and provide consistent operational performance. Hypertherm has developed this Preventive
Maintenance Program (PMP) specifically for your MAXPRO200 plasma system.
If you have questions about how to maintain your Hypertherm plasma system, contact your regional Hypertherm Technical
Service team. Contact information for each regional office is available at:
http://www.hypertherm.com/en/About_us/Contact_us/index.jsp
The PMP has two parts: a cleaning and inspection plan and a component replacement plan.
Cleaning and inspection plan
This plan consists of a daily, weekly, and monthly schedule of cleaning and inspection tasks. Detailed instructions in
support of each task are included in the PMP to help guide your production and maintenance personnel in understanding
what to do and what to look for during each prescribed task.
Table 1on page 4 outlines the cleaning and inspection schedule. A monthly log sheet, found on the back cover of this
manual, allows you to make photocopies so your production staff can record the tasks they have performed and can
anticipate the tasks they must perform before the end of the month.
MAXPRO200 Preventive Maintenance Program Instruction Manual 808800 3
Cleaning and inspection schedule
In general, Daily and weekly tasks are tasks that the operator might perform while the monthly tasks are more likely to be
performed by maintenance personnel.

Verify inlet pressures
1. With gas flowing in the 004 diagnostic mode (Flow gas at full pressure), verify
that the pressure at each supply regulator is set to 6.2 bar (90 psi).
2. For complete instructions about setting supply regulators, see Setting the supply
gas regulators in your system’s instruction manual (807700).
Inspect all air filters
1. Inspect all air filters for moisture, oil, and particulates.
2. If moisture or oil is present, replace the air filter.
3. If a moderate amount of dust or other particulates is present, blow or
vacuum it out of the filter.
4. If there is a large build-up of dust or particulates, replace the air filter
(011093). Refer to Air filter element replacement in your system’s
instruction manual (807700) for replacement details.
Verify coolant level and condition
Verify that the coolant tank is full. If the level is below the full line, add Hypertherm premixed
coolant (028872). Record the number of gallons your system requires in Coolant requirements
on page 21.
Inspect the coolant tank for dirt and particulates. If either are present:
1. Drain the tank. Locate the coolant drain valve and use a 20 liter (5 gallon) container to catch the
coolant. Coolant will flow as soon as the drain is opened.
2. Close the drain when the coolant stops flowing.
3. Fill the tank with clean coolant or water and run the pump to flush
the system.
4. Drain the tank again.
5. Refill the coolant tank to the full line with clean coolant.
6. Run the system to fill hoses and leads with coolant.
7. If necessary, add more coolant to the tank. Refer to Fill the power
supply with coolant in your system’s instruction manual (807700) for
more details.

1. Remove the black o-rings on the torch and replace them if they are damaged.
O-rings, bullet plugs, a water tube, and silicone lubricant are available for the main torch body of the quick disconnect
torch as part of kit 228780. See kits 428333 or 428334 for o-rings, a water tube and silicone lubricant for the
straight torch. Other o-rings are included with the consumables.
2. Apply a thin film of silicone lubricant (027055) to all o-rings.
3. The o-rings should look shiny, but there should not be any excess or built-up lubricant.
4. Replace all o-rings so they fit snugly.
5. Inspect all threaded consumables and remove any dirt in the threads.
6. Reassemble the torch.
Inspect the water tube and torch for damage
1. Verify that the water tube is not bent and has no pitting. Replace the water tube
(220521) if it is damaged.
2. Verify that the nozzle and electrode mating surfaces on the torch main body are not
damaged and have no pitting.
3. Use a clean cloth to wipe off the torch inside and outside. Use a cotton swab to
access hard-to-reach internal surfaces. Verify that you do not leave any cotton fibers
inside the torch main body.
4. Use compressed air to blow away any remaining particulates from internal and
external surfaces.

Inspect hoses and leads
Visually inspect all air hoses, coolant hoses, and torch leads for wear, restrictions, or both. Look especially for:
Scrapes or cuts
Punctures
Chemical spills or burns
Kinks or bends that restrict flow or damage the hose or lead.
Replace all damaged hoses or leads. Refer to Part numbers for MAXPRO200 cables, hoses, and leads on page 20 for
lengths and part numbers.
Inspect for gas leaks
For more information, see Gas leak tests in the Maintenance section of your system’s instruction manual (807700).Verify
coolant flow
For more information, see Coolant flow test in the Maintenance section of your system’s instruction manual (807700).
Verify coolant flow
1. Turn ON the power to the power supply and select the coolant flow
icon on the front panel of the power supply BEFORE the purge cycle
is complete. The flow switch will be overridden and coolant will
continue to flow for 30 seconds.
2. Record the flow rate in the maintenance log at the end of this
document.
Check coolant level
1. Open the cover of the coolant tank on the top of the power supply enclosure.
2. Verify that the tank is full of coolant.
3. If the level of coolant is below the full line, add coolant until it reaches the full line.

Monthly cleaning and inspection instructions
WARNING!
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
All work requiring removal of the power supply cover must be performed by
a qualified technician.
See the Safety section of the system’s manual for more safety precautions.
Clean inside the power supply
1. Turn OFF the power to the power supply.
2. Remove the top and side panels.
3. Blow out or vacuum any accumulation of dust and particulates from:
The top and side panels
The inside of the power supply
Fans
4. Gently remove dust and particulates from circuit boards, taking extra care not to damage them.
5. Replace the top and side panels before you turn ON the power.
Check for coolant system leaks
Inspect the coolant-circulating system for coolant leaks at all connection points. Primary locations to inspect are:
The torch main body
The internal connection in the power supply
8 MAXPRO200 Preventive Maintenance Program Instruction Manual 808800
Inspect the main contactor
Visually inspect the main contactor for excessive pitting and for blackened or rough surfaces on any of the contacts. If this
condition exists, replace the main contactor.
Perform coolant flow test
The control board receives an electrical signal in Hz from the flow sensor, that is converted and shown as flow in gallons
per minute (gpm). Normal flow is 4.5 lpm (1.2 gpm), but this will vary depending on lead lengths and whether the power
is 50 Hz or 60 Hz. PCB4 will allow the system to operate if the coolant flow is 1.9 lpm (0.5 gpm) or greater. If the system
shows a coolant flow error (093) the system will need to be turned OFF and then ON again and the following test needs
to be performed to determine if the problem is coolant flow or the flow switch.
1. Turn OFF the power, and remove the right-side panel from the power supply.
MAXPRO200 Preventive Maintenance Program Instruction Manual 808800 9
2. Disconnect the return hose from the top of the coolant tank. Push the connector-collar toward the fitting, and pull the
hose away from the fitting This will release the coolant hose. No tools required. Put the end of the return hose into a
4 liter (1 gallon) container.
3. You will need to enable the flow function before the count reaches 5 in the 3-digit display. Turn ON the power and
press and release the current knob twice until the flow function is enabled. Turn OFF the power after the coolant
flows for 30 seconds.
4. Measure the amount of coolant in the container. There should be about 2 liters (0.5 gallon). If there is less than 1 liter
(0.25gallon) there may be a restriction in the coolant system or a problem with the pump or flow sensor.
5. Verify the flow sensor output by measuring the flow output (in frequency) at the control board. Measure the
Frequency on J21 pin 3 (pulse) and pin 2 (ground). Once you have the frequency use the chart below to get the flow
sensors measured flow rate. If this number differs more than 0.8 lpm (0.2 gpm) from your bucket test, the flow sensor
may need to be replaced.

Inspect gas line connections
Check all supply gas line connections by spraying them with soapy water. If bubbles appear on a gas line, tighten the
connection or replace it as necessary. Refer to Part numbers for MAXPRO200 cables, hoses, and leads on page 20 for
lengths and part numbers.
CAUTION!
Do not clean brass connections with ammonia-based cleaners. Ammonia causes brass to crack and
become brittle.
Inspect for hose restrictions
Check for hose restrictions as follows:
Check each hose to verify that it has no kinks or sharp bends that can restrict gas flow or damage the hose.
If the cutting table uses a power track system to support leads from the power supply to the gas console or torch,
check the position of the leads in the power track to ensure the leads do not twist or kink, causing a possible
restriction.
Inspect cables
Check all cables for scratches or unusual wear. If the outside insulation has been cut or otherwise damaged, replace the
cable. Refer to Part numbers for MAXPRO200 cables, hoses, and leads on page 20 for lengths and part numbers.
Inspect the ground connections
Verify that all components of the system are individually grounded to a driven earth ground, as described in the
Installation and Grounding section of your system’s instruction manual (807700).
Inspect the table-to-workpiece connection
Check the work lead (+) connection, particularly where the work lead (+) connects to the cutting table.
To prevent arc-transfer problems, there should be no paint, oil, or dirt on the workpiece that would prevent a clean
metal-to-metal contact between the work lead and the cutting table or workpiece.
12 MAXPRO200 Preventive Maintenance Program Instruction Manual 808800
Component replacement plan
This plan lists the components and their recommended replacement schedule after 500 hours of accumulated arc hours
of use (1 year for hand torches). See Table 2 – Mechanized torch parts replacement schedule on page 14 for the
component replacement schedule.
Hypertherm believes that using arc hours is the most accurate method of monitoring the proper time to replace a
component. We have provided a guide that will help you to estimate an arc-hours-per-year model, based on the average
number of 8-hour shifts during which the system operates on an average work day..
Finally, we want you to understand that the component replacement plan is a starting point. Your operating environment
and cutting applications can accelerate the wear rate of some components within your plasma system. We have
highlighted the most likely environmental and application factors that can lead to accelerated component wear.
The following tables and checklists are provided so you can record relevant information about your system and its
replacement requirements:
Part numbers for MAXPRO200 cables, hoses, and leads on page 20
System voltage on page 21
Coolant requirements on page 21
Component replacement schedule
The component replacement schedule found in – Mechanized torch parts replacement scheduleTable 2– Mechanized
torch parts replacement schedule is based on the cumulative arc hours of the cutting system, for mechanized torches,
and is calendar based for hand held torches. The hand held torch maintenance schedule is based on a 500 arc hours per
year model. Use table 2 to determine when components should be replaced to maintain the system's optimal
performance and to minimize unplanned downtime during the life of the system.
You can estimate the system's cumulative cutting time using the following guides:
Mechanized torches
Average number of shifts per day Estimated number of arc hours per year
1 shift 500 arc hours/year
2 shifts 1000 arc hours/year
3 shifts 1500 arc hours/year
Hand held torches
Average number of shifts per day Estimated time for maintenance
1 shift Every twelve months
2 shifts Every six months
3 shifts Every four months

Environmental and application impacts
The component replacement schedule serves as a starting point for your replacement plans. Your operating environment
and cutting applications may include conditions that accelerate the wear rate of some components within your plasma
system. This accelerated wear will increase the frequency of component replacements. This section highlights the top
environmental or application-specific conditions known to decrease the life expectancy of components in the
MAXPRO200 Manual Gas plasma system.
Several environmental and application-specific conditions are described in the following sections. While the quantifiable
effect of each condition on the expected life of your system's components is difficult to determine, each condition is
known to have a negative impact on system performance and the life expectancy of certain components.
Review each section for the explanation of the effect on your system and components that each environmental condition
can have. If any of these conditions apply, consider adjusting your component replacement schedule.
If you have questions about the details of your replacement schedule, contact your regional Hypertherm Technical Service
team.
Poor compressed air quality
To maintain optimal performance of your system, it is important that the source of incoming air is free of contaminates
such as dirt, oil, and water. If the incoming air contains contaminates, system components can become clogged or fail to
function properly. Poor air quality usually results in increased system errors, poor cut quality, or both. The most common
components to be affected by contaminated incoming air are:
Air filter elements, solenoids and check valves. Debris in these parts limits the flow of air in the system, resulting in
poor cutting performance and gas errors (044, 053, 057, 058).
The quick-disconnect torch head. Debris in this part restricts air flow and reduces cut quality. Oil in the system may
also cause a fire in the torch head as the oil reacts with the oxygen cutting process.
Pressure sensors. Debris in these sensors can cause false pressure readings, resulting in cut performance issues
and gas errors.
If you have poor incoming air quality, consider adjusting the replacement schedule for the following components:
Description Part number
Filter element 011093
Mechanized torches - See Table 2 – Mechanized torch parts replacement schedule on page 14 for part numbers
Handheld torches - See Table 3 – Handheld torch parts replacement schedule on page 15 for part numbers
Gas assembly 428034
Pressure transducer 428042
If you can, improve the quality of the air that enters your system to prevent this condition from impacting the life of your
system. Contact your regional Hypertherm Technical Service team if you need help or advice on the best way to improve
incoming air quality.
16 MAXPRO200 Preventive Maintenance Program Instruction Manual 808800
Short cut cycle time
Applications where the cut sequence is very short, such as those that include cutting many small holes or frequent
markings for numbers and letters, can cause premature wear of torch parts and starting components. In these types of
applications:
The shield, retaining cap, and torch main body are exposed to more heat and stress during piercing, which can
deform the components and make them more difficult to replace.
The starting components, such as the high frequency transformer and the high frequency ignition board, can wear out
faster than normal and result in misfires and error codes (020, 021).

If you allow consumables to reach complete failure, they can melt and pieces of copper can break off and enter into the
coolant. In the coolant, these pieces of copper can:
Become caught in the torch head and torch receptacle and can obstruct coolant flow and increase coolant flow
errors (093) or damage consumables by allowing them to overheat.
Become caught in the coolant filter and pump, which can cause coolant flow errors (093) or excessive wear in the
coolant pump.
Shorten the life of the check valve if copper pieces lodge on the inside of the seal of the valve and cause coolant to
leak when you change consumables.
Shorten the life of the coolant flow switch by obstructing the movement of the sensor wheel within the switch and
cause inaccurate coolant flow readings and coolant flow errors (093).
When you perform maintenance checks, inspect the coolant filter for melted copper pieces. If you find pieces of copper in
the coolant filter, both the filter and coolant must be replaced. If coolant flow errors (093) occur after you replace the filter
and coolant, the troubleshooting procedure in your system’s instruction manual (807700) to determine the appropriate
action.

Metal dust inside power supply cabinet
One of the byproducts of plasma cutting is metal dust. If metal dust builds up inside the plasma power supply cabinet, the
life expectancy of some components will be shorter than expected. Periodic cleaning inside the power supply is strongly
recommended to extend the life of the fans and coolant pump motor. For cleaning details, see Clean inside the power
supply on page 8.
If metal dust builds up on fans (main power supply, chopper, and heat exchanger) it can reduce their output level or stop
them from working, resulting in temperature-related errors (065, 066, 067, 071).
The coolant pump motor can also be impacted by metal dust, which results in overheating or stopping the motor.
If you have metal dust inside your power supply, consider adjusting the replacement schedule for the following
components:
Description Part number
Front fan 027079
Heat exchanger fan 127091
Coolant pump motor 428039
Dirty external work environment
Metal dust and dirt that collect on unused and unprotected consumables and torch assemblies can cause the following
conditions:
Metal dust and dirt from the cutting process will prevent o-rings and seals of the torch heads and receptacles from
sealing properly. Incomplete seals can allow dirt and grease to be trapped in parts of the torch head.
Torch heads and receptacles that are not protected from the elements will have to be changed or repaired more
frequently.
Metal dust and dirt that build up on the torch and consumables may enter the coolant system and create excessive
wear on the pump. In this type of environment, the coolant pump may have to be replaced more frequently.
The flow switch uses magnetic pick-ups and will be affected by a coolant system that has dirt and metal dust trapped
in it. Flushing the coolant system will help, as well as cleaning the flow switch. However, you may need to replace the
coolant switch to recover proper functionality of the coolant loop system.

The simplest way to address the effects of a dirty work environment on your consumables or torch heads is to store them
within a covered space, away from metal dust and dirt. Another solution is to use compressed air to blow the dust or dirt
off these parts before you install them.
If you cannot store your consumables and torch heads in a covered space, consider adjusting the replacement schedule
for the following components:
Description Part number
Mechanized Torches - See Table 2 – Mechanized torch parts replacement schedule on page 14 for part numbers
Handheld torches - See Table 3 – Handheld torch parts replacement schedule on page 15 for part numbers
Quick-disconnect torch receptacle 420033
Coolant pump 428043
