1.IMPORTANT INFORMATION
1.1 SERVICE ASSISTANCE AND CONTACT INFORMATION
For service assistance, have the following information available:
• HP105 model, part and serial number located on a label
• Type of cutting application you are using
1.2 RECEIVING AND UNPACKING
After receiving the HP105 you should:
• Carefully, unpack and inspect the equipment.
• Compare the received shipment with the packing list.
• Report any damage to the carrier and your representative.
• Store equipment that will not be used in a clean, dry location.
• Take appropriate precautions to prevent moisture, dust and dirt
from accumulating in storage and installation areas.
1.3 SAFETY CONSIDERATIONS
Safety practices should not be an after thought. Before installing
or servicing the controller, review and follow applicable policies and
procedures to ensure worker safety. Machinery must be in a safe
state and you must be aware of any additional hazards that can
arise.
1.4 PRE-INSTALLATION CONSIDERATIONS
Before installing the HP105:
• Check to be sure that you have all of the required parts.
• Familiarize yourself with the parts of the HP105.

第- 3 - 页 共 23 页
• Check to be sure that the torch lifter motors you are using with
the HP105 are within the acceptable range.
• Review the instructions for Configuring the Lifter Mechanics.
1.5 CONFIGURING THE LIFTER MECHANICS
Proper configuration of the torch lifter mechanism is an
important factor for establishing the accuracy of your cutting system.
Be sure that:
• Gear reduction is selected on the torch lifter so that the
maximum suspension speed does not exceed 3000 mm/min (120
IPM). If higher accuracy is required, maximum suspension speed
should be set to 1500 mm/min (60 IPM).
• Gears, racks and spindles have minimal backlash.
• Oversizing is avoided. The mass of moving parts, including
armature inertia must be as small as possible. Motors with low
nominal RPM are preferred.
2. Brief Intro
2.1 Summarize
HP105 plasma arc voltage height controller is equipped with
constant current plasma . During cutting course, the current
always equals the given current. And the cutting arc voltage will
be changed with the fixed speed being the height of torch changing.
When the distance gets farther ，the arc voltage increases; On
opposite, the arc voltage will decrease. HP105 plasma arc voltage

height controller will inspect the voltage change, then control the
distance between cutting torch and material via the lift motor. So
that the arc voltage is fixed, the same is the height of cutting torch.
Generally, the instruction will list all the cutting parameters for
some type of plasma . The user can refer to these parameters.
Adjust the voltage in arc voltage height controller to match the
selected current. The torch height will keep constant under regular
speed.In fact,the user should set the arc voltage according to the
height of the cutting torch.
In the status of automation ,the arc voltage more high,then the
height of the cutting torch more high

3. installation and commissioning
3.1 Work process:
When CNC system’s output arc signal to the HP105’s interface J2-4，
the height controller should process the IHS firstly; Secondly
auto-control the Arc-on, the height controller will send the signal of
arc transfer and pierce transfer to the NC system after producing
the transfer arc. At the mean time, the controller delay time to put
the arc voltage into the single chip system. If “Auto Permitted is
available in height controller and NC system has sent out AUTO
height adjusted signal, the controller is on status of “Height Auto
adjusted”
ATTN: When the cNC system that you use can not receive the
signal of arc-on and pierce, please delay the time to control the NC
system’s running. It just means that the cNC system send arc-on
signal to the height controller, delay time to run the cNC system.
3.2 INSTALLATION CONTROLER ：
The following section provides you with the procedure to follow
when installing the HP105 Some of the steps direct you to other
sections in this manual that provide you with more detailed
instruction.

1. Determine a mounting location for the HP105. Keep the
following points in mind:
To avoid overheating and potential damage to the control box
from cutting process fumes, DO NOT choose a mounting location
directly above the torch.Find a mounting location away from the
torch lifter unit.
2. Attach the wires from the CNC,the plasma,the lifter motor and
lifter limit switches to a connector and then to the control box at the
receptacle. To reduce noise emission, 20 AWG (0.5 mm2) shielded
cable is recommended. Filters consisting of a resistor and capacitor
can be connected only directly to the motor.
3. Connect a 12 AWG (2.5 mm2) ground wire to the ground
screw located on the control box and then, to the machine ground
rail of your cutting system.
3.3 Divided voltage board
Controlling the arc voltage must inspect the changing of plasma
arc voltage. The plasma arc voltage equals the voltage that is
between the pole and ground. The anticathode which put out the
plasma power is connected to the ground. The Cathode connects
to the pole which is in the cutting gun. So the voltage in the

HP105 Plasma arc voltage height controller

electrode is negative. When process the cutting, the arc voltage
absolute value is usually higher than 100V. If so, the voltage must
be divided in order to process the control in the controlling circuit.
ATTN: the voltage that put into the height controller is negative.
If the polarity is connected in reverse, the Height Auto-adjusted is
not available.

with 50: 1 non-isolated sub-plate plasma can set the input of 50: 1 low
pressure (in this case the partial pressure ratio of 2: 1).

Two types of IHS style of height controller
1. Plasma Shield protector IHS inspecting style
The material of the protector should be metallic. They can
transmit each other when it gets to the material.
ATTN ：The cutting torch protector IHS inspecting style is
suitable for abover-water cutting only.
Single
Working process: After the height controller receives the arc-on
signal which is sent out from NC system, the cutting torch will fall
down immediately. When the protector get to the material, the
height controller will receive this signal, and then control the cutting
torch to rise to the given Height of IHS. The height controller will

control the plasma to arc on after IHS.
2. inductive proximity switch IHS style(switch mode: NPN
Mode, 2mm, outer diameter Ф12, the distance of screw
thread:1.0mm)
When this style is adopted, the client should design the tongs
according the IHS cutting torch tongs sketch map which is provided
by our company. All the plasma IHS, whatever over-water cutting
and under-water cutting, can adopt this IHS style. Please adopt the
approach switch IHS style if you use the high frequency input arc
plasma and under-water cutting.
The tongs sketch map: Please see the appendix
Before IHS, the approach switch is on approaching status. The
cutting torch will rise once the switch is broken away.
Working process: After the height controller receives the arc-on
signal which is sent out from NC system, the cutting torch will fall
down immediately. When the cutting torch gets to the material, the
approach switch will break away from the approaching spot. The
height controller receives this signal, and then controls the cutting
torch to rise to the given Height of IHS (the approach switch will
reposition automatically during the rising). The height controller will
control the plasma to arc on automatically after IHS. This IHS style
is suitable for all plasma IHS.
