Best metal cutters for 2020

A metal cutter is a professional device that is rarely used in the household field. Thanks to such a device, a person can perform cutting of any complexity, and some models are used for jewelry work. For those who are just going to buy this device, it is important to know what to look for and the best representatives. For this reason, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of metal cutters for 2020.

Types of gas cutters

There are hundreds of models from various manufacturers on the market, but the classification is based on such criteria as:

• Cutting method. Most often, two methods are distinguished: surface and separating, the first type is usually used.
• The cutters can be hand-held or mechanized.
• Also, the difference concerns the types of fuel used by the device. So there are propane, methane, acetylene and kerosene cutters.
• By design, there are two types of models: with an injector and without.
• In addition, the differences lie in the type of mouthpiece used and the oxygen supply, which can be low or high pressure.

There are hundreds of types of devices on store shelves that are produced by both domestic and foreign manufacturers. Most of them are distinguished by the complexity of modifications and ergonomics, but they are all similar in design. So, regardless of the price category, the device has a handle, a valve that regulates the fuel supply, and a tip where a flame is formed.

Injection Type Cutter Features

Such devices make it possible to use combustible fuel of different pressures: from low to high. When oxygen passes through the injector, a rarefaction effect is created (this is done in a special chamber) because of this, gas is sucked in. After that, the resulting mixture enters the head.

Regardless of the manufacturer, there are 4-6 mouthpieces in the cutter package, thanks to which high-quality and high-speed cutting of metal is ensured, the thickness of which should not exceed 20 cm (when working with acetylene). In addition, the kit contains 7 internal elements that can handle material up to 30 cm (propane-butane). Also some models may have some modifications of external mouthpieces.

It is important to understand that some cutters are manufactured to work with specific metals of a certain thickness, so, for example, to cut carbon or low-carbon steel (the thickness of which does not exceed 10 cm), then a person needs to have a device that is designed to work with acetylene and propane-butane ... In order to cut through thick metal, it is important to select a device that is capable of handling both acetylene and propane and methane. Then the person will get high efficiency.

Inline mixing torches

In such devices, mixing takes place in special channels that are located between the outer sleeve and the mouthpiece.To supply oxygen, a person needs to use a lever valve; for gas, a separate regulator is used, located on the torch handle.

When buying such a device, it is important to know that there are no universal models. Cutters are available in 3 versions: designed for work with acetylene, propane and methane. In addition, such devices have a high level of safety, since the gas is mixed in the head, and not at the handle. However, such a constructive solution is often more expensive than the previous version, therefore it is used in industry.

Kerosene-oxygen devices

Such cutters for metal have more significant differences in design compared to gas cutters. This is due to the method of obtaining a flame, because it is necessary to convert a liquid into a gaseous state. This operation takes place in the evaporator, where the kerosene is heated by the heating element.

Fuel is supplied under a pressure of 30 kPa and passes from the tank through a special hose. To ensure safety, the tank has a special safety valve and a pump. The tank can hold about 8 liters of fuel. The use of such a device is indispensable for field work.

Plasma cutters

Some types of work cannot be carried out with gas appliances, then the best option is to buy a plasma cutter. However, it is important to understand that such devices differ from each other not only in special capabilities, but also in design. Also, there are differences in the way the arc is ignited and the cooling system used.

There are compact mobile models that can be easily transferred from one point to another. In addition to this option, there are entire gantry installations that are designed to perform complex production tasks.

Most plasma cutters are divided into 5 categories:

• Devices designed to perform assigned tasks in an environment of inert and shielding gases.
• Models capable of operating in an oxidizing environment - places with a high oxygen index.
• Devices designed to form with various mixtures.
• For work in stabilizers.
• Magnetically stabilized equipment.

Also, the difference between devices occurs according to the type of energy consumed. So there are household cutters that are actively used to perform simple tasks and work from a voltage of 220 V. Professional devices function only from 380 V, but their scope of application is several times larger.

It is important to understand that regardless of the energy consumed and the power indicator, it is necessary to check the device connected to the public network. In addition, it is worth remembering that a compressor with an average power is connected to the cutter. Therefore, it must also be taken into account when connecting.

Inverter torches

This is one of the best budget options that will cope with metal, the thickness of which will not exceed 30 mm. Such models are in great demand for small jobs in the household or in small workshops. Also a big plus is the low consumption of electrical energy and compactness.

90% of the models sold are easy to transport. This opens up the opportunity to work in hard-to-reach places. In addition, efficiency is a big plus, which is 30% higher.

Transformer type plasma cutters for metal

More expensive devices designed for medium jobs. They are able to cut metal up to 80 mm thick. It looks like a large box, the movement of which is due to the wheels. Weight and dimensions, respectively, more than the previous model.

The reliability of such devices is several times higher. Even in the event of voltage surges, transformer-type plasma cutters will not fail, and this makes it possible to work in regions where there is a problem with electricity.

Also an additional advantage is the operating time with uninterrupted switching, which is almost 100%. Therefore, the device is able to function throughout the whole day without any interruptions. However, despite the positive features, such models also have a negative side: high power consumption.

In addition to dividing models by type, torches are also distinguished by the type of contact. So there are contact and non-contact devices. The first model is capable of working with metals, the thickness of which does not exceed 18 mm, and the second version works with any thickness.
