• Fumes and gases produced when cutting are hazardous to health. Make sure to work in
places where there are exhaust or ventilation facilities to keep fumes or emissions away
from the breathing zone.
• Insulate the working area since spatter will be occurred.
• No access to switching or modulating by others while the cutter is working
• Cutters have strong electromagnetism and frequency interference, so keep away people
with heart pace or the articles which can be interfered by electromagnetism and frequency.
• No squeeze or punch to the cutting cable.
• Never clean the slag in the torch head by violent knocking.
• The puckering angle of the torch cable can not be too small, otherwise the inside cable of
gas pipe will be damaged which can result into accident.
• Never allow anybody else other than the operator himself to access the job site.
• No touching on the output connection or any other electrification parts while welding.
Safety Measures to Be Taken To Assure the Correct Installation and Position
• Precaution must be taken to keep the operator and the machine from the foreign materials
falling from up above
• The dust, acid and erosible dirt in the air at the job site can no exceed the amount required
by the norm (excluding the emission from the cutter).
• The cutting machine must be installed in the place where it can no be exposed to sun and
rain. Also it must be stored in less humid place with the temperature range at -10˚C~+40˚C.
• There should be 50cm space left for the cutting machine to have good ventilation.
• Make sure that there is no metal-like foreign body to enter the cutting machine.
• No violent vibration in the cutter’s surrounding area.
• Make sure the machine is installed in where it won’t interfere the surrounding electromagnetism
equipment during the operation.
• Take measures to prevent wind while operating in the strong wind since the cutter is gas
shielded.
Safety Check
Each item listed below must be carefully checked before operation:
• Make sure that the cutting machine has reliable earth connection.
• Make sure that there is always sound output and input wire connection instead of exposing
outside.
Regular check needs to be conducted by the qualified personnel after the cutter has been
installed over a period of six months, which involves as follows:
• Routine cleaning is required to make sure there is no abnormal condition happening in the
tightened places such as the loose and slipped magnetic core, regulating screw, connecting
wire happening in the cutting machine.
• The external parts installed on the cutter’s panel must guarantee that the Cutter works
properly.
• Fresh the cable of the cutter if it is worn out.
• Any damage to the input cable if occurred should be dealt safely.
• Make sure whether there is enough power supply to make the cutting machine work
properly, and the power supply connected into the cutter should be equipped with safety
protection device.
TECHNICAL SPECIFICATIONS
Environment for the Product
• The surrounding temperature range:
When cutting: -10˚C~+40˚C
During transport or in storage: -25˚C~+55˚C
• Relative humidity:
When at 40°C: ≤50%
When at 20°C: ≤90%
• The dust, acid and erosible materials in the air can not exceed the amount required by the
norm (apart from the emissions from the cutter ). No violent vibration at the job site.
• Keep out from raining when it is used outdoor.
Requirement for Main Supply
• The voltage oscillogram should display actual sine wave.
• The oscillation of the supplied voltage should not exceed ±20% of the rated value.
• Frequency fluctuation should be less than ± 2%.
Theory of Cutting Machine (see the principle chart)
The principle chart
POWER CUT 25K is high speed cutting equipment with advanced technology which is using
high density plasma arc as source of the heat. The plasma arc would be acquired by the
compressed air as ionization medium and the compression of the torch’s nozzle.
The main electric theory of POWER CUT 25K 240V single-phase industrial AC power is
required, and transfer to DC after rectified by Single phase rectification bridge and transformed
by the middle frequency transformer, and then rectified to the DC by the fast recovery diode,
While starting cutting, the nozzle and electrode are separated quickly by the air pressure, the
voltage between them make the air are ionization and arc which is moved between work piece
and electrode pilots .
Cutter’s Structure
POWER CUT 25K applies portable box structure: power indicator light, protect indictor
light, the cutting current adjust knob, are installed on the first half of the front board; and
the current output ‘+’ electrode quick connector, ‘-’ electrode quick connector, cutting torch
control(two pins socket), switch socket are installed on the next half; the power inlet, Argon
input connector and power switch, are installed on the back board; the control transformer,
control press circuitry board can be seen on the first installation board after shelling the out
