Painting of various items and surfaces with such a device as a paintopult implies the creation of a high-quality and uniform layer of good density, without the formation of any irregularities or herds. In principle, this tool can do it without difficulty, especially if connected to a good compressor. But the simple connection may not be enough to get a quality result. So that the power of the spray gun is fully disclosed, it should be properly adjusted by installing the best pressure, as well as some other indicators. We will try to figure out what the scheme of this process and which for this should be implemented.
Begins to adjust the collapse with torch adjustment. This element will be responsible for the area for which paint will be sprayed. If you need to cut a large surface over the area, then you should set the maximum value or close to it. If you need to combine several colors or make applying to a small area, this parameter will better reduce. Change is performed using a special regulator that should be twisted either in the direction of magnification or in the opposite.
When installing the lever at a maximum layer of spraying it will be very thin, so the paint on the edges will be dry. Moreover, it will cause too high paint consumption and entail unnecessary financial spending, besides, it will be necessary to spend extra time for kneading. It is better to configure this: unscrew the regulator until it is maximum, after which it is a little twist it in the direction of reduction.
Add that To apply paint, the torch is kept in a vertical position, but for painting bottlenecks should be changed its corner almost up to horizontal.
But it should not put the mode of weak spraying, because the high concentration will cause strips and leakage.
Adjusting the input pressure
Another point regarding the setting of the paint tool – adjustment of the pressure of the input type. After all, it should be understood that the pressure of the paint emissions is determined by the pressure of the air, the regulation of which is made by a special valve. If the indicator is too high, then instead of an oval form will be obtained. And this means that the borders will be blurred, splashes – simply get beyond the boundaries of the contour. With a weak pressure, paint will form dense clots that will fall on the surface with a thick layer.
The simplest method of selecting the required level of pressure for beginners will be the following algorithm:
- fully open the valve;
- At a distance of 250-300 millimeters we produce a trial spraying;
- twist the regulator in the direction of lowering until the stain will not have the desired shape, and the paint-applied layer will not become homogeneous.
If for some reason, the splashes can not be removed, and the paintopult continues to “spit”, and does not spat out paint, it suggests that a block formed in the device and it takes to clean it.
Naturally, it is worth noting that if the spray is new, then such a problem may not occur.
In addition, the configuration of the device can be done using a regulator with a pressure gauge, which is located at the handle. When the air moves, part of the pressure disappears. But the regulator makes it possible to correctly select pressure.
If the device is equipped with a pressure gauge of the built-in type, then there will be no problems. The setting will be done like this:
- The flare width control screw is fully opened;
- It is required to press the sprayer’s trigger;
- The required pressure level is established due to the air mass regulator.
If the painting gun has a separate device, the input pressure setting will be made as follows.
- Screws that are responsible for the speed of air flow and changing the size of the clouds should be installed at maximum. Paint spraying speed will not play roles.
- On the spray arm, it is necessary to pressed in such a way that the gas supply of compressed type starts. When you turn the adjusting screw on the pressure gauge, you need to select the necessary input pressure. If the paintopult is conventional, then we are talking about the values of 3-4 bar. If a low-pressure model is 1.5-2 bar.
- Now you should install the kraskopodachi regulator to the maximum position. When the operator is verify that all screws are installed in the desired position, and the viscosity of the paint is as needed according to the norm, you can start testing the device.
If the gun does not have measuring elements at all, then you can try to establish an exemplary pressure level, using the filtering mechanism pressure gauge or compressor gearbox. Here should be taken into account two aspects.
- Pressure in an unguded filter should be about 0.3-0.5 atmospheres. If it is clogged, the recommended value rises five times.
- Part of the pressure disappears as the air masses are moved along the hose. We are talking about the value of about 0.6 atmospheres.
To prepare a device for use, unscrew the screw of gas supplies to the maximum. Then open the cloud size regulator and click on the trigger.
It remains to establish pressure on the gearbox, accepting the loss.
Now let’s talk a little about the following stages of the setting of the sprayer, which can be useful for painting the tree or applying the coloring agent to other types of surfaces. Let’s start with paint.
When the torch size of the torch was installed and the best pressure level is set, you can start setting up paintopod. For such purposes, the paintopult is equipped with a special system responsible for regulation of paintopod. At the start of testing it should be twisted to the end, after which it is gradually twisting to the other side as test prints apply. Professionals advise not to install the high level of paint from the very beginning, because in a similar way you can accidentally be consumed by the entire stock of the composition and spoil the surface exposed to processing.
If the feed is carried out at a too high level, then there is a danger that the painting camera will be contaminated. With such a type of work per unit of time, the consumption of the material will be too high, and small delays in the use and small distance of the device from the surface are the cause of elements that are difficult to call aesthetic.
For this reason, the reduced level of material feeding will look more preferably, because if desired, it is significantly easier to raise the feed level than to reduce it.
To understand exactly how best to set up a spray paint for painting of various kinds of surfaces, you should have at least a small base of knowledge about how paints and varnish materials are supplied to such a device.
There is nothing complicated here, because the feed mechanism consists of a steel needle that covers the inlet, the course of which is limited to the aforementioned screw adjustment.
The simplicity of such a design allows the operator to produce operational and the most insignificant changes in the mode of operation of the device, depending on the needs and established situation.
Distance to the surface
If we talk about such an aspect as the distance to the surface, then there is no uniform opinion among specialists and experts. Some say that for metal or any other surface, the distance between it and the paintopult should be about 10 centimeters, and others – up to 30 centimeters. Such a big difference is explained very simply – everywhere different models are used that have different characteristics, including power. It will be better to comply with the following recommendations:
- for HVLP – 100-150 millimeters;
- for LVLP – 150-200 millimeters;
- For dispensers of conventional character type HP – 200-250 millimeters.
How to set up a gun with different tank location?
It should be said that in the market you can find models with the top and with the lower arrangement of the paint tank. The second option will be easier. Both types of models have certain features.
- The model with the top tank will be an excellent solution for working with a high degree of viscosity. It is also convenient to use under varnish. But applying such a device is not very convenient due to the fact that it is always required to keep it under the same angle, which is not so simple if long-term work is supposed. The change of material in this case will also be not the easiest process, due to which the paint material in the container in full.
- A device having a capacity below can be called more practical. Its only feature will be that it is not suitable for working with paint with high viscosity.
It is required to say that the location of the reservoir over the handle is somewhat inconvenient in terms of hand fatigue. For example, if you can easily hold the tank below the second hand, then when it is located on top, it is significantly more difficult.
That is, the only advantage of the model with the top tank will be the fact that it is better only when the paint is applied to viscosity.
Device setup should also be taken into account aspects.
- Keep the gun from the surface constantly at the same distance. We are talking about the values of 20-30 centimeters.
- Deviation of the collapse to side is invalid. If the hand is tired, it is better to take a break. It is clear that without minimal oscillations it will be difficult to do, but if they are too strong, then the paint on the surface will be distributed unevenly.
- When spraying on the ends, it is not necessary to save paintwork, producing deviation of the device from a strictly vertical position. It is better to spend a little more substance than to encounter low quality coverage.
- The first layer should be applied horizontally, and the second vertical. The displacement of the bands should be carried out by 30-60 millimeters, there should be good drying between the layers and absolutely absent adhesion.
- Staining speed in normal mode – 30-40 millimeters per second, and should not deviate from these values. Keep the device should be smoothly and move as smoothly as possible.
Setting up paint tools for beginners may seem extremely difficult, if not to adhere to the aforementioned moments.
But with their observance, even an inexperienced person can carry out the correct setting of collapse.
