What Is A Plasma Cutter?

A plasma cutter is a new type of thermal cutting machine for metal fabrication, which uses working gas and plasma arc with high-speed & high-temperature as the heat source to melt the metal locally, and blow away the molten metal with high-speed airflow at the same time to form a narrow plasma cut seams. It is used to cut various metals, like carbon steel, stainless steel, copper, aluminum, cast iron, and more. It makes it possible to cut through electrically conductive metals with precision. It features with high cutting speed, thin cut seams, low deformation, small heat-affected zone, easy-to-use, and energy saving. With the pilot arc, it will generate a low power plasma arc in the air, which make the cut with lower cost. It is used in sheet metal fabrication, metal structure making, machinery building, repair shop, drilling, digging, beveling, patching and more metal cut projects & plans.

What Are The Advantages of Plasma Cutting?

Plasma cutting is an efficient metal cutting method for sheet metal and metal tubes, which has made it to be widely used in many different industries. 

You can get benefits from 10 best advantages with fast cuts, ease of use, lower cost, safe to use, multi-tasking, expanded versatility, wide range of material and thickness, eliminated plate warping, raised inside piercing speed, and diminished dross.

Compared with traditional manual & semi-automatic metal cutting method, automatic CNC metal cutting system is an integration of quality improvement and cost-efficiency. CNC metal cutting machines include computerized numerically controlled plasma, flame, water jet and laser cutting machine. It performs automatic, full-time, high-quality, high-utilization and efficient cutting according to the CNC nesting software.

In industrial production, metal thermal cutting generally includes gas cutting, plasma cutting, and laser cutting. Compared with gas cut, plasma cut has a wider cutting range and higher efficiency. The fine plasma cut system is close to the quality of laser cutting in terms of the cutting surface quality of the material, but the cost is much lower than that of laser cutting.  It has shown great advantages in saving materials and improving labor productivity. This has promoted it from manual or semi-automatic to numerical control, and has become one of the main directions of the development of numerical control cutting technology.

1. It can cut thicker metals, such as stainless steel, aluminum and its alloys, copper and its alloys, cast iron and other metal materials. You can also use plasma gun to cut insulating materials and non-metallic materials with thickness of more than 150mm.

2. The cutting speed is fast, and the production efficiency is high, especially when cutting thin metals with high power, the production efficiency is improved more significantly.

3. The cutting quality is high, the slit is smooth and flat, the incision is narrow, and the heat-affected zone and deformation are smaller than other cutting methods.

4. Low cost, due to the high speed, the use of cheap gas such as nitrogen requires less raw materials and labor than other methods to cut the same material.

How Thick Can Plasma Cut?

Plasma CNC cutting ability: According to the size of the configured power supply, the cutting thickness is generally within 0.5-100mm, and the high power supply can cut to more than 100mm; CNC flame cutting ability: Ordinary flame cutting torch 6-180mm (maximum 250mm), special flame cutting torch generally does not exceed 300mm, of course, it can also be customized to be higher.

How To Choose A Dust Collector for CNC Plasma Cutting Table?

A material receiving and dust removal device for a plasma CNC cutting machine includes a workbench composed of a bracket and a grid-like work surface fixed on the top of the bracket. The bracket is provided with a material receiving plate that can move horizontally relative to the workbench and is located in the bottom of the grid-shaped work surface, and the material receiving plate is a steel wire mesh plate, the bottom of the workbench directly below the material receiving plate is provided with a dust removal water tank, and the bottom of the dust removal water tank is provided with wheels. The material receiving and dust removal device enables the workpieces and wastes cut by the machine and dropped below the working table to be easily taken out, and at the same time, it can greatly reduce the metal dust pollution generated when cutting the workpiece.
