plasma arc cutting machine unstable fault analysis

Plasma arc cutting machine cutting quality directly affects the stability of the plasma arc instability will lead to cuts uneven buildup and other defects, can lead to

The control system related to reduced life components, nozzles, frequent replacement of the electrode. For this phenomenon, analyze and propose solutions.

1 pressure is too low

Plasma cutting hose crimping machine work, such as working pressure is far below the required specification pressure, which means that the ejection velocity plasma arc weakened, input air flow

Is less than the predetermined value, this time can not form a high energy, high speed plasma arc, resulting in poor cut quality, not cut through, cut buildup phenomenon. Insufficient air pressure of the original

Due to: lack of input air compressor, air regulator valve regulator cutting machine is too low, the solenoid valve within the oil, gas path is not smooth and so on.

The workaround is to use the former to observe compressor output pressure display, if not met, adjust the pressure or compressor overhaul. If the input air pressure has reached the required

, You should check the air filter regulator adjusted correctly, gauge display can meet the cutting requirements. Otherwise deal with air filter regulator routine maintenance, indeed

Paul input air dry, no oil. If you enter the air quality is poor, it will cause the solenoid valve to generate oil, valve open difficulties valve port can not be fully opened. Furthermore,

Torch nozzle pressure is too low, the need to replace the solenoid valve; pneumatic smaller cross-section can also cause pressure is too low, according to the specification requirements replace the trachea.

2 pressure is too high

If the input air pressure far exceeds 0.45MPa, in the form of plasma-arc, excessive concentration of air being blown arc column, so that the arc column energy dispersion, weakened

Intensity of the plasma arc cutting. Caused by excessive pressure causes: improper input air regulator, air filter regulator is too high or the air filter regulator failure


The workaround is to check whether the right to adjust the pressure air compressor, air compressor and air filter regulator whether the pressure imbalance. Boot, such as a rotary air filters Less

Pressure valve adjustment switch, gauge unchanged, indicating that the air filter regulator failure, need of replacement.

3 burning torch nozzle and electrode

Due to improper installation nozzles, such as threaded not tighten the device to adjust the gear properly, need water cooled torch at work, did not seek to pass into the flow of cooling water to the

And frequent arcing will cause premature failure of the nozzle.

The solution is cutting the workpiece in accordance with the technical requirements of the gear equipment properly adjusted, check the torch nozzle is installed securely imprison, need to pass cooling water nozzles should provide

Before the cooling water circulation up. Cutting, adjust the thickness of the workpiece between the torch and the workpiece distance.

4 AC input voltage is too low

The use of plasma cutting machine has a large field of electricity facilities, cutting internal main circuit component failures, etc., causes the input AC voltage is too low.

The workaround is to check plasma cutting hydraulic machines connected to the grid have sufficient carrying capacity, power cord specifications meet the requirements. Plasma cutting machine installation site

Point, you should stay away from large-scale electrical equipment and often have electrical interference. Use, should be cleaned regularly cutting machine dust and dirt on the component, check the wires are

Whether the aging phenomena.

5 Ground poor contact with the workpiece

Grounding is an essential preparation before cutting work. Dedicated ground unused tool, the surface with an insulating material and the long-term use of the ground so serious aging,

Will cause poor contact with the workpiece ground.

The use of specialized tools to be ground, and check the ground insulation effect surface contact with the workpiece, to avoid aging ground.

6 does not automatically break arc sparker

Plasma cutting machine work, we must first plasma arc ignition by high-frequency oscillator excitation electrode and between the inner wall of the gas nozzle to produce high-frequency discharge, the gas

Local ionization of the formation of small arc, this small arc by action of compressed air, ejected from the nozzle to ignite a plasma arc, which is the main task sparker. Normal

, The spark generator working time is only 0.5 ~ 1s, the reason is not automatically broken arc is generally offset control circuit board components, discharge electrode spark gap generator


Sparker should always check the discharge electrode, so that the surface remains flat discharge adjust sparker electrode gap (0.8 ~ 1.2mm), if need be,

Change control board.

7 Other

In addition to these reasons, the cutting speed is too slow, cutting torch and the workpiece verticality, as well as the operator of the plasma cutting machine familiarity, operational level, etc.

All affect the stability of the plasma arc, the user should pay attention to these areas.

high pressure hose assembly cleanliness
Pipe cleaning industrial enterprises in the country, you need to shut down, shutdown, use a metal brush, a blower, oil or chemical solvent cleaning, high pressure water jet, etc., that increase costs, but also pollute the environment, cleaning a long time, can not be cleaned pipe, After washing with residual chemicals, but also to the user at risk.
        To introduce you to a more rapid and efficient method of cleaning. Currently Caterpillar, Volvo, John deere and other companies are using.
        Otto Brooklyn hoses and innovative cleaning system uses a pneumatic pipe emission gun, firing a bullet through a hose or pipe cleaner. A pump has been damaged, in which the output of the last few gallons of oil in a large number of metal fragments, flows to the downstream system. Rinse with solvent and air is very cumbersome, and sometimes the effect is not ideal. But Otto Kling system can be quick and simple solution to the problem of clean hydraulic hose crimping machine system piping. And it makes you free from tedious and rigorous chemical process. Simply remove the two ends of the hose assembly, can be injected into a specially designed projectile. Cleanliness up NAS1638-4 grade of this product is the high-pressure hose
