If you are installing a new control board skip to step 4.
3. Remove and discard the old chip by using the tool included in this kit. See pictures below.
a. Place the straight end of the chip removal tool under one corner of the chip. Only 2 opposite corners will
accept the tool.
b. Carefully pry each of the 2 corners alternately until the chip is removed. Prying the chip out from only one
corner can damage the chip receptacle.
4. Chose the appropriate chip from fi rmware kit 228571 (located in the main kit box), and install it in the chip
receptacle on the control board.
Use the chip labeled 081192 for an RHF system.
Use the chip labeled 081194 for an LHF system.
Note: NOTE: The chip must be oriented correctly before installation. DO NOT use the orientation of the label to
orient the chip to the chip receptacle. There is a bevel on one edge of each chip and one corner is
angled (see fi gure below).

5. If you are installing a new control board see Installation of the new control board on the next page.
If you have installed the new chip on an existing control board see step 2 of Installation of the new control
board on the next page, before you replace the 2 front panels of the power supply and continue to torch and
quick-disconnect installation.

3. Label each connector before removing any connections to the old board. After labeling the connectors,
remove all connections to the control board. Any wires that are present but not connected to the board will
remain disconnected.
4. Remove the 6 screws that hold the control board in place, and remove the old control board. Save the screws
for reuse.
5. Install the new control board using the six screws from step 3.
6. Plug all the connectors into the appropriate receptacles on the new control board.
7. Replace the 2 front panels and continue to torch and quick-disconnect installation.

Torch and quick-disconnect receptacle Installation
1. Remove the existing torch and mounting sleeve from the lifter.
2. Unscrew the mounting sleeve and slide it up to expose the hose fi ttings.
3. Disconnect all the hoses and the pilot arc connection from the torch and remove the sleeve.
Always use 2 wrenches to loosen or tighten the fi ttings.
4. Inspect all hoses and wires for damage.
5. Loosen the off-valve assembly to remove the existing blue plasma hose.
6. Hold the black plasma hose provided in this kit with the bundled cables and hoses and slide the HyPro2000 torch
mounting sleeve over the leads (with the threaded end closest to the torch) and install the pilot arc lead insulator onto the
pilot arc lead (dark blue hose).

7. Connect the torch quick-disconnect receptakce to the torch leads.
a. The coolant hose insulator is on the coolant return (red) line of the torch quick disconnect when shipped.
Make sure it is in place before making any connections.

13. Install the torch onto the quick-disconnect receptacle.
a. Align any of the matching dots on the torch and quick-disconnect receptacle, and slide the torch into the
receptacle. 3 triangular dots are shown below, but there are also single dots that match and double dots
that match.
b. Turn the threaded collar on the torch clockwise until it is tight

14. Verify gas pressures.
a. Turn on the power to the system and turn on the gas supplies.
b. Adjust the gas console settings for the chosen process using the cut charts in this document.
c. Verify the gas pressure reading on the gauge between the plasma gas line and the off-valve assembly with
the table below.
Note: Recommended incoming gas (supply gas) pressures are 120 psi for oxygen and nitrogen and 90 psi for air.
If the incoming gas pressure are not set correctly the back pressure reading will also
be incorrect.
15. Verify that there are no leaks at any of the connections.
16. Remove the pressure gauge that was installed in step 12 and the installation is complete.
Prior to start-up, ensure that your cutting environment and that your clothing meet the safety requirements outlined in the
Safety section of the system’s instruction manual.
Check torch
WARNING
Before operating this system, you must read the Safety section thoroughly! Turn OFF the power
supply’s main disconnect switch before proceeding with the following steps.
1. Turn OFF the main disconnect switch to the power supply.
2. Remove the consumables from the torch and check for worn or damaged parts. Always place the
consumables on a clean, dry, oil-free surface after removing. Dirty consumables can cause the
torch tomalfunction.
• Refer to Install consumables on the next page for details.
• Refer to the Cut charts to choose the correct consumables for your cutting needs.
3. Replace consumable parts. Refer to Changing consumables later in this section for details.
4. Ensure that the torch is perpendicular to the workpiece.

Install consumables
WARNING
Always disconnect power to the power supply before inspecting or changing torch consumable parts. Use gloves
when removing consumables. The torch might be hot.
Install consumables
Check the consumable parts daily for wear before cutting. Before removing consumables, bring the torch to the edge of
the cutting table, with the torch lifter raised to its highest point to prevent the consumables from dropping into the water
of the water table.
Note: Do not overtighten parts! Only tighten until mating parts are seated.
Apply a thin film of silicone
The o-ring should look shiny, but there should not be any excess or
built-up grease.

Arc voltage
The arc voltage settings (v) shown in the cut charts may need to be adjusted to produce the correct cutting height.
Physically measuring the height after stopping the torch is preferred, but visual inspection during a cut is acceptable.
Over the life of a consumable set it will also be necessary to periodically adjust the arc voltage (v) up 1 to 2 volts at a
time to maintain the proper torch height and to achieve the maximum life from the consumables.
Cut charts
The following Cut charts show the consumable parts, cutting speeds, gas pressures, and the current settings required
for each process.
The numbers shown in the Cut charts are recommended to provide high-quality cuts with minimal dross. Because of
differences between installations and material composition, adjustments may be required to obtain desired results.
Digital remote
Hypertherm has produced a few versions of the digital remote. Some versions increase and decrease in 10 amp
increments, and some increase and decrease in 20 amp increments. If you have a digital remote that increases/
decreases by 20 amps, set the digital remote to 120 amps or 140 amps for a 130 amp process. The system will
automatically choose the 130 amp process.
