Inverter plasma

Types of inverter plasma

An inverter plasma is cutting equipment that uses plasma technology to cut different types of materials. There are various types of plasma cutters available for sale on the market now.

• Air Plasma Cutters

  An air plasma cutter uses compressed air as plasma gas to cut through metals. It can cut through almost any conductive material, including steel, aluminum, copper, brass, and titanium. Users of the device must ensure the air compressor is tidy and meets the pressure requirement, which is between 70 and 80 psi. The benefit of using an air plasma cutter is that, unlike other plasma cutters that use different gases, it is easy to come by and use an air compressor as a cutting gas.

• Shielded Plasma Arc

  The shielded plasma arc cutter impedes arc diffusion by using the flowing granules of glass and fluoride plasma. The method improves concentration and makes it less obstructed. This increases the quality and output of the cut, making shielded plasma arc cutters an attractive option for those looking for a good quality but affordable plasma cutter.

• Hig Frequency Plasma Arc

  High-frequency arc plasma cutters make use of high-frequency arcs to initiate ionization of the plasma gases. The implementation of the high-frequency arcs allows for non-contact pilot arcs. This makes it easier for the cutter to start operating. The benefits of high-frequency plasma cutters include fast starting speed, smooth operation, and cut quality. However, it is essential to note that high-frequency plasma cutters are susceptible to electromagnetic interference. Therefore, they may require additional noise filters and electronic components to reduce the effect of EMI.

• Non-Touch DC Plasma Arc

  Non-touch direct current plasma arc cutters work without pilot touching arcs. They ionize gas in the torch, which strikes an target metal. It creates a narrow cut the width of the arc. Non-touch DC plasma arcs have small heat-affected zones. This makes them useful for precision cutting in thin material. They minimize distortion and damage. In addition, non-touch DC plasma cutters are easy to use and don't require contact with the workpiece to start an arc. This makes starting faster and reduces tip wear.

• Thermal Dynamic Plasma Cutters

Thermal dynamics plasma cutters work without pilot touching arcs. They ionize gas in the torch, which strikes an target metal. It creates a narrow cut the width of the arc. Non-touch DC thermal dynamic plasma cutters have small heat-affected zones. This makes them useful for precision cutting in thin material. They minimize distortion and damage. In addition, thermal dynamic plasma cutters are easy to use and don't require contact with the workpiece to start an arc. This makes starting faster and reduces tip wear.

Specifications and Maintenance

• Input voltage: 110V plasma cutters work with single-phase 110V/120V electricity. They suit environments using standard household electricity. 220V plasma cutters use single-phase 220V/240V power and are for business sites where this higher voltage is common.
• Cutting capacity: The thickness of metal a plasma cutter can cut depends on its current rating. For example, a 30A plasma cutter typically handles metal up to 1/4 inch (6mm) thick. Higher current models cut thicker metal. A 40A plasma cutter can cut materials up to 1/2 inch (12mm). A 60A plasma cutter is for metals up to 7/8 inch (22mm).
• Air compressor: Plasma cutters that use compressed air need an air compressor to generate that air. The cutter specifies what size compressor it needs in cubic feet per minute (CFM) of compressed air produced. A small compressor producing 5 CFM works with small plasma cutters. Larger compressors with 14 CFM output are for industrial-grade cutters that massage more metal.
• Electrode and nozzle sizes: The plasma cutter has an electrode and a cutting tip, or the nozzle is made in different sizes to cope with various kinds of jobs. Some jobs need to cut a thin arc, and some need to cut a wider arc; depending upon the size needed, the cutter works better with a specific type.
• Working environment: The place a plasma cutter is used must be free from flammable and explosive gasses. Plasma cutters use oxygen and compressed air to cut through metals. They can ignite any flammable materials and become explosive.

Maintenance tips

• Always follow the instructions provided by the manufacturer. Proper handling can be more important to the longevity of a plasma cutter than maintenance.
• Only use extensions and cords approved for plasma cutters. This helps ensure the safety of the operator and the cutter.
• Wear proper safety gear when operating the cutter. This includes goggles and a face shield to protect against flying metal shards. It may also include hand protection if the cutter produces a high level of heat.
• Store the cutter and its hoses in a protective case whenever possible. This helps prevent damage to the equipment.
• Hoses should not be twisted or bent sharply during transport to avoid kinks or damage.
• Visually inspect the cutter prior to use. This includes examining the torch and its parts to ensure they are intact, functional, and free of damage.
• Protect the input voltage cable and oxygen and air hoses from burns and splashes while cutting. Keeping them away from any object being cut helps prevent burns and damage.
• Regularly clean the customer's parts, including the cutting torch, to prevent clogs and ensure the proper function.

Application scenarios for inverter plasmas

The plasma cutter inverter machine is a versatile tool used in various industries for cutting different types of metals. Here are some of the common application scenarios for this machine:

How to choose an inverter plasma

• Output power:

  The output power of the inverter plasma cutter determines its cutting capacity and whether it can handle thick materials. When selecting the appropriate inverter plasma cutter output power, the material thickness and type must be considered.

• Cutting thickness :

  It is crucial to match the plasma cutter's output power to the material thickness to be cut. Different plasma cutters are designed for various thicknesses, so ensure the chosen cutter has sufficient power to cut through the materials at the required thickness.

• Arc restriking:

  Ensuring quick arc-restriking is essential for maintaining productivity and efficient cutting. This feature allows the plasma cutter's arc to reignite instantly if it extinguishes temporarily, such as when cutting through gaps or interruptions in the material. Quick arc-restriking reduces downtime and minimizes the need for manual intervention to restart the cutting process.

• Protective Components:

  Consider a plasma cutter with protective components, such as a thermal overload protector, to prevent damage from prolonged use or overheating. The thermal overload protector automatically shuts off the plasma cutter when it detects excessive heat, protecting the internal parts from damage. Choosing a cutter with this protector can prolong its lifespan and maintain its optimal performance.

• Operating Voltage:

  The operating voltage of a plasma cutter indicates the input power needed to operate the equipment. Plasma cutters typically have low voltage (such as 110/220V) and high voltage (such as 380/440V) options. It's essential to select a cutter with a voltage compatible with the available power supply. Additionally, some plasma cutters have a voltage display on the front panel, allowing users to monitor and adjust the input voltage to ensure proper operation.
