4’x8’ Plasma Cutter for Metal Cutting

4×8 plasma cutter machine is a type of equipment used for metal cutting, typically with a plasma arc. The dimensions “4’x8′” refer to the size of the cutting table or bed, which measures 4 feet in width and 8 feet in length. This means the machine can accommodate metal sheets or plates up to that size for cutting.

Plasma cutting is a process that utilizes a high-velocity jet of ionized gas, known as plasma, to melt and sever metal. The plasma arc is created by passing a gas, such as compressed air or nitrogen, through a small nozzle at high speeds and then introducing an electrical arc that ionizes the gas. The resulting plasma arc can reach temperatures of up to 30,000 degrees Fahrenheit (16,650 degrees Celsius) and can effectively cut through various metals, including steel, stainless steel, aluminum, and copper.

A 4’x8′ plasma cutter machine is commonly used in industrial settings, fabrication shops, and metalworking industries where large-scale metal cutting is required. It offers the advantage of high cutting speeds, precision, and versatility in terms of the types and thicknesses of metals it can cut. The machine may include additional features such as automated CNC (Computer Numerical Control) systems for precise and repeatable cutting patterns.


There are many kinds of power sources for the customer to choose according to the metal thickness. Such as 65A,80A,100A,125A ,160A and 200A. And the working size of the plasma cutting machine is also customized.

Plasma Cutter Machine Advantage & Features

  • The Plasma Cutting Machine can cut all metal sheets. The cutting area is very wide.
  • The cutting speed of the metal cutting machine is very fast and the efficiency is high. The cutting speed can reach more than 10m/min.
  • The cutting precision is higher than the flame cutting machine. The underwater cutting has no deformation, and the fine plasma cutting has higher precision.
  • The Plasma Cutting Machines use a professional plasma CNC system. It is all offline work and humanized operation.
  • The CNC Plasma uses the advanced USB interface to work offline with fast data transmission and does not occupy computer resources.
  • This  Metal Cutting Machine can be compatible with a variety of software.
  • The machine is with the function of continued carving when power outages and breakpoints. And the function of processing time prediction and automatic tool setting.
  • Affordable factory direct price and one-year warranty.

Plasma cutting is a fast and precise method of cutting metals, and is often preferred over other methods such as oxy-fuel cutting or laser cutting. The plasma cutter machine is controlled by computer software, which allows for precise and repeatable cuts, even in complex shapes and designs.

When operating a plasma cutter machine, it’s important to follow proper safety procedures, including wearing protective gear such as eye protection and gloves. The machine also requires regular maintenance, including cleaning the torch and replacing consumable parts such as the nozzle and electrode.
