2.PRODUCT DESCRIPTION
2.1 Function Overview
This is a new Pro series plasma cutting machine with advanced technology, complete
functions and excellent performance. This ultra-portable plasma cutting system is suitable
for a variety of application needs. In addition, the new series is also
equipped with the latest APP remote control function.
Advanced digital control
The CUT55NON-HF plasma cutting machine adopts
advanced MCU intelligent digital control technology, and all
major components are operated by software.
Large screen display and multi-scene mode:
The product supports grid cutting, rust removal, plate cutting
and other modes. Users can choose the required working
mode according to the usage scenario.
Grid cutting adjusts the PA time 5-15S to avoid frequent start-up of the cutting gun
switch. The rust removal mode can perform simple metal rust surface rust
removal.
The upgraded LED display supports different working modes and function
switching such as current, voltage, air pressure display and unit switching;
Multi-function mode:
The function mode supports 2T/4T/PT/PA mode, and functions such as back-air
4
supply and safety protection can be easily read through the digital display.
Full digital control improves the consistency and stability of cutting, while making
the cutting machine more compact and cutting more precise.
Powerful cutting performance
Using non-high frequency technology, the IPT60 cutting torch realizes non-high
frequency non-contact arc ignition. In this mode, the cutting torch head does not
need to contact the metal plate, which prolongs the life of consumables and
increases the cutting thickness.
Dual voltage mode
CUT55NON-HF is a versatile plasma cutting machine that can use 110V/220V
AC voltage. It uses compressed air as the plasma gas source to cut metal, so
make sure your air compressor is ready. The device outputs 220V stably to cut
carbon steel with a maximum thickness of 26 mm, and is also capable of cutting
other metals such as stainless steel, copper, cast iron and aluminum.

3.2 Nameplate
On the machine, there is a plate that includes all the operating specifications for your new
unit. The serial number of the product is also found on this plate.
The duty cycle rating of a plasma cutter defines how long the operator can cut and how
long the cutter must rest and be cooled. Duty cycle is expressed as a percentage of 10
minutes and represents the maximum cutting time allowed. The balance of the 10-minute
cycle is required for cooling.
For example, a plasma cutter has a duty cycle rating of 60% at the rated output of 55A.
This means with that machine: you can cut at 55 A output for six (6) minutes out of 10 with
the remaining four (4) minutes required for cooling. The duty cycle of your new plasma
detection function, the air valve
will automatically open and air
will flow out from the nozzle of
the gun head. This means that
the machine's gas path is
normal. If the user does not
automatically switch back to PSI
or MPA mode after 3S, the air
valve will automatically close and
return to PSI or MPA mode.
Please note that when the air
check function is on, any
cutting mode will not work.
Warning
: The machine
cannot cut when it is in PT/PA
mode. It can only cut when it is
in 2T/4T mode.

be securely connected to the
workpiece.
Figure 15 Clamp the Ground clamp
3. Set the output current control knob
at maximum position for higher
cutting speed and less dross
formation. Reduce the current, if
desired to reduce the cut width,
heat affected zone or travel speed
as required.
4. You can refer to Appendix 1 to set
cutting parameters

15
1. When ready to cut, place the torch
near the work, make certain all safety
precautions have been taken and pull
the trigger. The pilot arc will start.
2. Pierce the work piece by slowly
lowering the torch onto the metal at a
30° angle away from the operator.
This will blow the dross away from the
torch nozzle. Slowly rotate the torch
to vertical position as the arc
becomes deeper.
NOTE: Graphics shown are for
understanding torch angles for best
results – the distances from the
workpiece are exaggerated. In actual
operation, the nozzle should be held
just above the work piece surface.
Figure 17 Cutting operation
NOTE
For better torch control, it is acceptable to let the nozzle drag along the work piece surface.
This will shorten nozzle life. Also, it is acceptable to place a non-conductive torch guide on
the work piece in order to achieve a cleaner cut
• When the trigger is released, the arc will stop. The gas will continue to flow for 5 seconds
of postflow. If the trigger is activated within this time period
• If the dross is difficult to remove, reduce the cutting speed. High speed dross is more
difficult to remove than low speed dross.
• The right side of the cut is more square than the left as viewed along the direction of
travel.
• Clean spatter and scale from the nozzle frequently.
Parts in place
Cutting torch reference Figure 7 cutting torch head. If the accessories of cutting
torch need to be replaced, please log in to the official website:
WWW.ARCCAPTAIN.COM
• Check the assembly of the torch consumables. If they are not properly in place, the
machine will not start. Make sure that the shield cup is hand tight. Do not use pliers
or over tighten.
• Check the conditions of the inside of the nozzle. If debris has collected, rub the
electrode on the inside bottom of the nozzle to remove any oxide layer that may have built
up. Refer to the “Routine Maintenance Section".
16
• Check the condition of the electrode. If the end has a crater-like appearance, replace it
along with the nozzle. The maximum wear depth of the electrode is approximately .062”. A
green and erratic arc will indicate definite electrode failure and the electrode should be
replaced immediately.
• Replace the nozzle when the orifice exit is eroded away or oval shaped.
Pilot arc discussion
The CUT has a smooth, continuous pilot arc. The pilot arc is only a means of transferring
the arc to the workpiece for cutting. Repeated pilot arc starts, in rapid succession, is not
recommended as these starts will generally reduce consumable life. Occasionally, the
pilot arc may sputter or start intermittently. This is aggravated when the consumables are
worn or the air pressure is too high.
Always keep in mind that the pilot arc is designed to transfer the arc to the workpiece and
not for numerous starts without cutting. When the pilot arc is started, a slight impulse will
be felt in the torch handle. This occurrence is normal and is the mechanism which starts
the plasma arc. This impulse can also be used to help troubleshoot a "no start" condition.
5.3 Notes for cutting operation
! WARINING BEWARE OF ELECTRIC SHOCK!
It is recommended not to ignite the arc in the air if not necessary, for it
will shorten the lifespan of the electrode and nozzle of the torch.
If the gun switch is pressed for more than 3 seconds without contact
with the workpiece, the arc will be closed.
It is recommended to initiate the cutting from the edge of workpiece,
unless penetration is needed.
Ensure spatters fly from the bottom of workpiece while cutting. If
spatters fly from the top of workpiece, it indicates that the workpiece
can not be fully cut because the cutting torch is moved too fast or the
cutting current is too low.
Keep the nozzle slightly touching the workpiece or keep a short
distance between the nozzle and workpiece. If the torch is pressed
against the workpiece, the nozzle may stick to the workpiece, and
smooth cutting is unavailable.
For cutting round workpiece or to meet precise cutting requirement,
molding board or other assistant tools are needed.
It is recommended to pull the cutting torch while cutting.
17
Keep the nozzle of cutting torch upright over the workpiece, and check
if the arc is moving with the cutting line. If the space is not enough,
don’t bend the cable too much, step on or press upon the cable to
avoid suffocating of gas flow. The cutting torch may be burned
because the gas flow is too small. Keep the cutting cable away from
edge tools.
Clean up the spatters on the nozzle timely, for it will affect the cooling
effect of the nozzle. Clean up the dust and spatters on the torch head
after using everyday to ensure good cooling effect.
The workpiece is not cut fully. This may be caused by:
1. The cutting current is too low.
2. The cutting speed is too high.
3. The electrode and nozzle of the torch are burned.
4. The workpiece is too thick.
Molten slag drops from the bottom of workpiece. This may be caused by:
1. The cutting speed is too low.
2. The electrode and nozzle of the torch are burned.
3. The cutting current is too high.
5.4 Cutting parameters table
! WARINING BEWARE OF ELECTRIC SHOCK!
Select proper current according to the cutting parameters table, workpiece material,
cutting thickness and cutting speed, etc. (The figure in the below table is an
approximation.)

5.5 Replacement of electrode and nozzle
18
! WARINING BEWARE OF ELECTRIC SHOCK!
When the phenomena below occur, the electrode and nozzle should be replaced.
Otherwise, there will be strong arc in the nozzle, which will break down the electrode and
the nozzle, or even burn the torch. Nozzles of different models are different, so ensure the
nozzle is of the same model when replacing it.

Turn on the machine, the LED screen
illuminates, the control PCB keys do
not function, and there is no response
when pushing the torch trigger.
The cutting machine crashes: Shut down the
machine, and restart it.
the LED Display E60
/E10/E31/E34/E80/81
1.E60 overheat protection: machine is under
overheat protection and stops working
until E60 disappears
2.E10 over-current protection:internal
components are damaged, please
contact dealer for help
3. E31 Input network voltage undervoltage
protection:
Under AC120V net voltage input user
turn off the power switch, the display will
light up E31 after 1S clock, and the display
will go out within 10S clock.
Warning:
Users cannot re-enter the AC120V/240V
network voltage within 10S of the display
not going out.If the user re-enter the
AC120V/240V network voltage within 10S
clock display E31 will not go out, the
machine can not work.

E34:
indicating that the IGBT drive voltage is
too low, and you need to contact the
manufacturer's after-sales service for help
5. E80 Input air pressure under pressure
protection:
When the input air pressure is less than 0.2MPa
(30Psi), the machine displays E80, which means the
current input air pressure is under pressure.Users
need to adjust the pressure reducing valve to adjust
the air pressure to 0.2MPa-0.55MPa (recommended
value is 0.4MPa or 57.5Psi).
6. E81 Input air pressure overpressure protection:
When the input air pressure is greater than
0.55MPa (80Psi), the machine displays E81, which
means the current input air pressure is
22
overpressurized.Users need to adjust the pressure
reducing valve to adjust the air pressure to
0.2MPa-0.55MPa (recommended value is 0.4MPa or
57.5Psi).
Turn on the machine, the LED screen
illuminates, and the fan works. When
pushing the torch trigger, the solenoid
valve functions, but there is no HF
discharge rustling.
The arc ignition part fails:
1.The inter electrode distance of the discharge
nozzle is too long.
2.There is leakage of the HF capacitor
222/10KV.
3.The mosfet or the optocoupler on the HF
board is damaged.
4.
The input voltage is too low.
Arc can not be ignited.
1. The air pressure is overly high or overly low.
2. Replace the electrode or nozzle
