What is a petrol cutter? Purpose and principle of operation of the tool

Among construction tools, devices for cutting and dismantling structures are included in a separate group. They allow you to remove debris, cut a piece of metal, or cut through a doorway. These include a gas cutter - this device is often used in rescue operations. How the device works and in what areas it is still used is described in this article.

Petrol cutter device

The tool is equipped with a gasoline engine, usually 2-stroke. It is mounted on the body and equipped with handles. A disk is mounted on the working part of the gas cutter, which makes the cuts. Its diameter reaches 30-40 cm. On one side, the disk is protected by a casing, ensuring safety for the operator.

If you study what a gas cutter is, you should also mention the principle of its operation. When the engine starts, torque is supplied through the belt to the drive, which rotates the cutting disc. In this case, the cutter has 2 tubes - one is connected to the gas tank, the other to the oxygen container. When the mechanism starts, gasoline enters the nozzle, and the supply of oxygen atomizes it and significantly increases the speed.

Purpose of the tool

We can say about a gas cutter that it is a special unit for cutting dense materials:

• concrete;
• asphalt;
• metal;
• granite;
• reinforced concrete;
• brick.

The main area of ​​application is rescue work, when you need to quickly dismantle rubble, enter a damaged room, or cut up a car after an accident in order to extract a person.

Essentially, this is a large grinder that runs on a gasoline engine. The tool is used not only for professional, but also for domestic purposes. For example, using such a device you can cut a technological or doorway. In some cases, capital buildings are dismantled and gating is carried out. This will require more powerful tools.

Types of gas cutters

The classification of these devices is mainly related to cutting technology:

• dry;
• wet.

In the first case, the work is carried out under normal conditions, and in the second, water is supplied to the disk and working surfaces, which flows through tubes. This reduces overheating and dust. Therefore, the device works noticeably longer - it does not need to be constantly turned off to cool down.

Thus, we can say about a gas cutter that this is a device that allows you to effectively dismantle structures even from very durable materials, including concrete and asphalt. The device is more often used in rescue work, although it can also be useful in everyday life. Depending on the purpose, more or less powerful tools are chosen.
