Manual non-contact cutting
(1) The torch roller is brought into contact with the workpiece, and the distance between the nozzle and the workpiece plane is adjusted to 3 to 5 mm. (The "cut thickness selection" switch is switched to the high level when the main unit is cut.
(2) Turn on the torch switch, ignite the plasma arc, cut through the workpiece, and move at the same speed in the cutting direction. The cutting speed is: the premise of cutting through, should not be slow. Too slow will affect the quality of the incision and even the arc.
(3) After the cutting is completed, the torch switch is turned off, and the plasma arc is extinguished. At this time, the compressed air is sprayed out to cool the torch. After a few seconds, the ejection stops automatically. Remove the torch and complete the cutting process.
Manual contact cutting
(1) The [cut thickness selection" switch is used in the low gear, and is used when the single machine is cut thinner.
(2) Place the torch nozzle at the starting point of the workpiece, turn on the torch switch, ignite the plasma arc, cut through the workpiece, and then move at the same speed in the direction of the slit.
(3) After the cutting is completed, the torch switch is opened and closed. At this time, the compressed air is still being sprayed, and after a few seconds, the spray is automatically stopped. Remove the torch and complete the cutting process.
Automatic cutting
(1) Automatic cutting is mainly suitable for cutting thick workpieces. Select the "Cut Thick Selection" switch position.
(2) After the torch roller is removed, the torch and the semi-automatic Cutting Machine are firmly connected, and the connecting parts are provided in the random accessories.
(3) Connect the power supply of the semi-automatic cutting machine. According to the shape of the workpiece, install the guide rail or radius rod (if it is a linear cutting guide, if the circle or arc is cut, the radius rod should be selected).
(4) If the torch switch plug is turned down, replace the remote control switch plug (included in the supplied accessories).
(5) Adjust the appropriate walking speed according to the thickness of the workpiece. Place the [pour" and [shun" switches on the semi-automatic cutting machine in the cutting direction.
(6) Adjust the distance between the nozzle and the workpiece to 3 to 8 mm, and adjust the center position of the nozzle to the starting strip of the workpiece slit.
(7) Turn on the remote control switch, cut through the workpiece, and turn on the power switch of the semi-automatic cutting machine to cut. At the initial stage of the cut, the cut seam should be kept in mind and adjusted to the appropriate cutting speed. And always pay attention to whether the two machines work normally.
(8) After cutting, turn off the remote switch and the semi-automatic cutting machine power switch. At this point, the entire process of cutting is completed.
Manual cutting
According to the material and thickness of the workpiece, select the single or parallel cutting method, and select the corresponding cutting method. Tighten the crossbar in the random attachment to the screw hole on the torch holder. If the length is not enough, it can be connected one by one. To the required radius length and tighten, then adjust the distance from the tip to the torch nozzle according to the length of the workpiece radius (the factor of the slit must be considered). After adjusting, tighten the top fastening screws to prevent loosening and loosen the cage to tighten the knurled screws. At this point, the workpiece can be rounded.


Production application
The advantage of the Plasma Cutting Machine is that the plasma arc energy is more concentrated, the temperature is higher, the cutting speed is faster, the deformation is small, and the materials such as stainless steel and aluminum can be cut.
The insufficiency of plasma cutting is that the arc is strong, the noise is loud, the dust is much, and there is a certain pollution to the environment. For medium and thick, many underwater plasma cutting is used, and the cutting thickness is also limited. Similarly, gas flow, arc length, telegraph quality, current magnitude, and cutting speed all affect quality, and it is not as easy to grasp as it is. The plasma cutting gun should not be more, because the cutting speed is faster, it is easy to be affected by the above factors, and the cutting quality is different. Generally speaking, for thin plate cutting, the surface quality of the plasma cutting incision is superior to that of the fire filling, and the hanging residue is rare.
In recent years, foreign manufacturers have developed a new technology called fine plasma or high-precision plasma, which has been introduced by domestic manufacturers. The effect is better. By improving the design of the cutting moment, the quality of the cutting surface of the workpiece is significantly improved, and the verticality of the edge can reach 0-1.5°, which is particularly advantageous for improving the cutting quality of the thick plate. Due to the improved cutting gun, the electrode life is increased several times. However, the distance between the cutting gun and the steel plate is relatively high, and the height sensor on the cutting gun is required to be more sensitive, and the torch lifting reaction is faster.
Therefore, the use of plasma cutting 4-30 mm steel plate is an ideal method to avoid the shortcomings of slow cutting speed, large deformation, severe cut of the incision and serious slag. A blank of a certain thickness of stainless steel or the like is obtained.

Cutting specification
1. No-load voltage and arc column voltage
The plasma cutting power supply must have a high enough no-load voltage to easily induce arcing and stabilize the plasma arc. The no-load voltage is typically 120-600V, and the arc column voltage is typically half of the no-load voltage. Increasing the voltage of the arc column can significantly increase the power of the plasma arc, thereby increasing the cutting speed and cutting a larger thickness of the metal sheet. The arc column voltage is often not achieved by adjusting the gas flow rate and increasing the internal pressure of the electrode, but the arc column voltage cannot exceed 65% of the no-load voltage, otherwise the plasma arc will be unstable.
2. Cutting current
Increasing the cutting current also increases the power of the plasma arc, but it is limited by the maximum allowable current, otherwise the plasma arc column becomes thicker, the slit width increases, and the electrode life decreases.
3. Gas flow
Increasing the gas flow rate can not only increase the arc column voltage, but also enhance the compression of the arc column, so that the plasma arc energy is more concentrated and the ejection force is stronger, thereby improving the cutting speed and quality. However, if the gas flow rate is too large, the arc column will become shorter, and the loss of heat will increase, so that the cutting ability is weakened until the cutting process is not performed normally.
4. Electrode shrinkage
The so-called shrinkage refers to the distance from the electrode to the end face of the cutting tip. The proper distance can make the arc get a good compression in the cutting nozzle, and obtain a plasma arc with concentrated energy and high temperature for effective cutting. If the distance is too large or too small, the electrode will be severely burnt, the cutting nozzle will burn out and the cutting ability will be reduced. The amount of shrinkage is generally 8-11mm.
5. Cutting height
The height of the cutting tip refers to the distance from the end face of the cutting tip to the surface of the workpiece being cut. This distance is generally 4~10mm. It has the same amount of shrinkage as the electrode, and the distance should be appropriate to fully utilize the cutting efficiency of the plasma arc, otherwise the cutting efficiency and the cutting quality will be lowered or the cutting nozzle will be burned out.
6. Cutting speed
The above various factors directly affect the compression effect of the plasma arc, that is, the temperature and energy density of the plasma arc, and the high temperature and high energy of the plasma arc determine the cutting speed, so the above various factors are related to the cutting speed. Under the premise of ensuring the quality of cutting, the cutting speed should be increased as much as possible. This not only increases productivity, but also reduces the amount of deformation of the cut parts and the heat affected area of the slotted area. If the cutting speed is not suitable, the effect is reversed, and the sticking slag is increased, and the cutting quality is lowered.
maintenance

1. Correctly assemble the torch
Install the torch correctly and carefully to ensure that all parts are well matched to ensure gas and cooling airflow. Installation Place all parts on a clean flannel to prevent dirt from sticking to the parts. Add appropriate lubricating oil to the O-ring, which is subject to the brightening of the O-ring.
2. Replace consumables in time before they are completely damaged
Do not replace the consumables with complete damage, as severely worn electrodes, nozzles, and swirl rings will create an uncontrolled plasma arc that can easily cause severe damage to the torch. Therefore, when the quality of the cut is found to be degraded for the first time, the consumables should be inspected in time.
3. Cleaning the connecting thread of the torch
When replacing consumables or routine maintenance inspections, be sure to clean the internal and external threads of the torch and, if necessary, clean or repair the connecting threads.
4. Cleaning the contact surface of the electrode and the nozzle
In many torches, the contact surface of the nozzle and the electrode is a charged contact surface. If there is dirt on these contact surfaces, the torch will not work properly and should be cleaned with a hydrogen peroxide cleaning agent.
5. Check gas and cooling gas daily
Check the flow and pressure of the gas and cooling air flow daily. If the flow is found to be insufficient or leaking, stop immediately to eliminate the malfunction.
6. Avoid torch collision damage
In order to avoid damage to the torch collision, it should be properly programmed to avoid the system from overrunning. The installation of the anti-collision device can effectively avoid the damage of the torch during the collision.
7. The most common cause of torch damage
(1) Torch collision.
(2) A destructive plasma arc due to damage to the consumables.
(3) Destructive plasma arc caused by dirt.
(4) Destructive plasma arc caused by loose parts.
8. Precautions
(1) Do not apply grease to the torch.
(2) Do not overuse the O-ring lubricant.
(3) Do not spray splash-proof chemicals while the protective cover is still on the torch.
(4) Do not use the manual torch as a hoe.
