Inverter plasma cutter

A plasma cutter is a tool used for cutting metals and other conductive materials. It operates by sending an electric arc through a gas that is passing through a constricted opening. With the intense heat created by the arc, the gas becomes plasma, which is hot enough to cut through metal. Inverter plasma cutters are a more advanced type of plasma cutter that uses inverter technology to provide a more precise and efficient cutting experience.

What is an Inverter Plasma Cutter?

An inverter plasma cutter is a machine that uses inverter technology to generate the electric arc necessary for cutting. The inverter technology allows for a higher frequency of the arc and more precise control of the cutting process. Compared to traditional plasma cutters, inverter plasma cutters are more lightweight, portable, and energy-efficient. They also offer better cutting quality and can operate on different input power sources.

Like traditional plasma cutters, an inverter plasma cutter consists of a power supply, a plasma torch, and a ground clamp. The power supply generates the electrical energy required for cutting. The plasma torch directs the plasma jet onto the material to be cut. The ground clamp completes the electrical circuit by connecting the workpiece to the power supply. An inverter circuit inside the power supply converts the incoming AC power into DC power. This DC power is then fed into the torch, where it ionizes the gas and creates the plasma arc for cutting. The inverter circuit allows for precise control of the output current and voltage, enabling the Vevor CUT50 to adjust to different cutting conditions. The inverter technology also contributes to the compact and lightweight design of these plasma cutters.

How does an Inverter Plasma Cutter Work?

An inverter plasma cutter works by converting the input power from the electrical grid into a high-frequency AC signal. This AC signal is then fed into a series of solid-state switches, such as insulated gate bipolar transistors (IGBTs), which are controlled by a microprocessor. These switches rapidly turn the DC signal on and off at a high frequency. The high-frequency DC signal is then transformed into a lower voltage and fed into a transformer, which increases the voltage to the desired level. The high-voltage DC signal is then rectified back into AC by a diode bridge. This high-frequency AC is then fed into the plasma torch, where it ionizes the gas to create the plasma arc for cutting.

The advantages of inverter plasma cutters are their portability, energy efficiency, and precise cutting capabilities. Their compact and lightweight design makes them easy to transport and use in various work settings. In terms of energy efficiency, the inverter technology allows for better control of the cutting process, resulting in less wasted energy and lower operating costs. Additionally, the precise control of current and voltage provided by the inverter technology enables these cutters to deliver clean and accurate cuts on a wide range of materials and thicknesses. These features make inverter plasma cutters popular in industries like metal fabrication, automotive repair, and construction.
