28 March 2023
Discover the advantages of plasma cutting robots and automate your metal fabrication process.
As manufacturing processes continue to evolve and improve, companies are increasingly turning to automation to enhance efficiency and precision. In this article, we will explore the different types of robots used for plasma cutting, the industries where these machines are commonly used, and how to integrate such a system into your manufacturing process.
Benefits of Plasma Cutting Robots
One area where the automation trend is particularly evident is in plasma cutting, a common method for cutting metals and other materials. While many manufacturers still rely on manual welders to perform plasma cutting tasks, it’s becoming more common to leverage plasma cutting robots to streamline their cutting processes and boost productivity.
However, the benefits of these machines go well beyond productivity and efficiency gains. Manufacturers find significant improvements in the following areas after automating their plasma cutting processes:
- Safety
- Consumable waste reduction
- Improved part quality
- Scrap reduction
- Advanced design capabilities
Safety
With automated cutting systems, workers can avoid the hazards associated with plasma cutting. Plasma robots reduce the risk of injury, such as exposure to fumes, sparks, and high temperatures.
Additionally, by reducing the need for manual labor, plasma cutting robots also minimize the risk of repetitive motion injuries and other physical strains. By investing in plasma cutting robots, companies can provide a safer work environment for their employees, which can lead to increased morale, productivity, and overall job satisfaction.
Consumable Waste Reduction
One of the main advantages of using plasma cutting robots is their ability to significantly reduce consumables waste. Consumables, like electrodes, wear quicker when the torch is used at the wrong distance from workpiece or if the user cuts the part too quickly.
These robots are programmed to perform tasks the same way every time. This allows manufacturers to use a minimal and predictable amount of consumable material–reducing consumable waste associated with mistakes and inconsistent cutting techniques.
Improved Part Quality
Plasma cutting robots are equipped with advanced technology that enables them to generate higher quality parts compared to manual cutting methods. With precise motion control and advanced sensing systems, plasma cutting robots can accurately and consistently cut through a variety of materials, producing parts that meet strict industry standards for quality and precision every time.
Advanced Design Capabilities
In addition to increased quality, plasma cutting robots are capable of cutting complex shapes and designs that would be difficult or impossible to achieve with manual cutting methods. By generating higher quality parts, businesses can deliver products that meet or exceed customer expectations, which can lead to increased customer satisfaction, loyalty, and access to additional revenue opportunities.
Scrap Reduction
With their ability to cut complex shapes with high precision, plasma cutting robots can help businesses optimize their material usage, reducing scrap and minimizing material costs. In addition, by automating the cutting process, plasma cutting robots can reduce errors and improve consistency, which also leads to a decrease in scrap. By reducing scrap, businesses can improve their bottom line and increase profitability.

Types of Plasma Cutting Robots
Plasma cutting robots come in various types, each with its own strengths and applications. Some robots are designed for high-speed cutting of thin materials, while others excel at cutting thicker materials with greater precision. Metals industries need to be able to cut parts with a broad range of shapes, compositions, and thicknesses. As with most applications, the application requirements should determine the type of robot manufacturers use.
Cartesian robots are the simplest type of plasma cutting robot, moving in straight lines along the X, Y, and Z axes. These robots are commonly used for plasma cutting of flat sheets and offer high precision and accuracy. However, their rigidity limits their flexibility and makes them less suitable for cutting complex shapes. They should be limited to small and simple cutting tasks.
Articulated, or six-axis robots, have several rotary joints, making them highly flexible and able to reach areas that are difficult to access. These robots are commonly used for cutting complex shapes and contours and offer high accuracy and speed. However, their complexity can make them more difficult to program and maintain. Articulated robots are also one of the more expensive options on this list.
SCARA robots have a similar design to Cartesian robots, but with a flexible arm that allows them to move in a circular motion. These robots are commonly used in plasma cutting applications where speed and precision are essential, such as in the automotive industry. Their circular motion allows them to reach around obstacles and achieve higher cutting speeds. However, their complexity can make them more difficult to program than Cartesian robots.
Collaborative robots are designed to work alongside humans and are commonly used for plasma cutting tasks that require human intervention or control. Like industrial six-axis robots, these robots offer high flexibility and can be easily programmed to perform a range of tasks. However, their lower speed and payload capacity make them less suitable for high-volume cutting tasks.
The choice of robot type will depend on the specific requirements of the plasma cutting application, such as the size and shape of the workpiece, the desired cutting speed and accuracy, and the level of automation required. Manufacturers should carefully consider the strengths and weaknesses of each robot type when selecting the best plasma cutting robot for their needs.
