Common problems in the application of plasma cutting machine
Plasma cutting electrical arc stability directly affect the cutting
quality, plasma arc unstable phenomenon, lead to incision is
uneven, product of melanoma defects, may also lead to the decrease
of the control system of the related components life, nozzle and
electrode frequent replacement. In view of this phenomenon, analyze
and propose solutions.
1 low pressure
"Plasma cutting machine work, such as work pressure far below
specifications required pressure, which means of the arc plasma jet
velocity weakening, input the air flow is less than the specified
value, this form of high energy and high speed of plasma arc,
causing the incision quality is poor, cut through, incision tumor
of the product phenomenon. Insufficient pressure of the reasons
are: air compressor input, cutting machine, air regulator low
voltage, electromagnetic valve oil, gas path is obstructed etc..
"The solution is, before use to observe the air compressor output
pressure display, if not meet the requirements, adjust the pressure
or the maintenance of air compressor. If the input pressure has
reached the requirements, should be properly adjusted check air
filter relief pressure valve, gauge display can meet the cutting
requirements. Otherwise deal with air filter relief pressure valve
for routine maintenance, ensure that the air dry, no oil. If the
input can cause poor air quality, oil solenoid valve, the valve
opening, the valve port is not fully open. In addition, torch
nozzle pressure is too low, also need to replace the solenoid
valve; gas road section variable is caused by pressure is too low,
according to the specifications for tracheal replacement.
2 high pressure
"If the input air pressure far exceed 0.45MPa, after the formation
of the plasma arc, the large flow of air will blow concentrated arc
column, the energy of arc column dispersion, decreased the plasma
arc cutting intensity. Cause the pressure is too high, the reasons
are: improper input air conditioning, air filter regulator is too
high or air filter valve failure.
The solution is to check whether the pressure of the air compressor
is adjusted properly, air compressor and air filter pressure relief
valve is dysfunctional. After startup, such as rotating air filter
relief pressure valve adjusting switch, gauge unchanged, indicating
that the air filter relief pressure valve failure, need to be
3 cutting torch nozzle and electrode
"Since the nozzle installation is improper, such as threads are not
tightened, equipment of each block bit improper adjustment, need
water cooling of the torch at work, not in accordance with the
requirements of pass into the flow of cooling water and frequent
arcs, will cause premature failure of the nozzle.
"The solution is, in accordance with the requirement of technology
of the workpiece cutting and the correct adjustment of equipment
gear, check the torch nozzle is installed firmly is, through the
cooling water nozzle should be made in advance in cooling water
circulation up. When cutting, cutting torch and workpiece thickness
adjustment according to workpiece distance.
4 input AC voltage is too low
Plasma cutting machine using the site has a large power use
facilities, cutting machine internal main circuit components, etc.,
will make the input AC voltage is too low.
The solution is to check whether there is sufficient capacity of
the plasma cutting machine access to the power grid, the power line
specifications are in line with the requirements. Plasma cutting
machine installation location, should be far away from large
electrical equipment and often have electrical interference place.
The use of the process, to regularly clean the dirt and dust
cutting machine components, check the wiring is aging etc..
5 poor contact with the ground
"The ground is essential preparation before cutting work a. Without
the use of special grounding tool, workpiece surface insulation and
long-term aging serious ground, will cause poor contact with the
Should use special grounding tool, and check whether the insulation
effect of the ground contact with the workpiece surface, avoid the
6 spark generator can't be broken arc
Plasma cutting machine, first of all to ignite the plasma arc, by
the high frequency oscillator excited gas between the electrode and
the inner wall of the nozzle, resulting in high-frequency
discharge, the gas ionization and the formation of local small arc,
the small arc by compressed air, ejected from the nozzle to ignite
plasma arc. This is main task spark generator. Under normal
circumstances, the spark generator working time is 0.5 ~ 1s, the
reason does not automatically break arc is generally offset control
circuit board components, discharge electrode gap of the spark
generator is not right.
Should always check the spark generator discharge electrode, make
the surface smooth, timely adjustment of the discharge electrode
gap spark generator (0.8 ~ 1.2mm), it is necessary to change
"In addition to the above reasons, the cutting speed is too slow,
cutting the verticality of the torch and workpiece, and the
operator of the plasma cutting machine familiarity, the operation
level and influence the stability of the plasma arc, the user
should notice in these aspects.
