Plasma Cutters DeWalt

DeWalt plasma cutting machines provide a solution for processing sheets and components made from electrically conductive metals. The brand was founded in 1924 through the work of Raymond DeWalt, inventor of the Wonder-Worker radial arm saw. From its first woodworking machines, DeWalt progressively expanded its international presence and its range for tradespeople and professionals. The distinctive yellow and black colour scheme now identifies tools and equipment developed for workshops, construction sites and technical work.

A plasma cutting machine can separate carbon steel, stainless steel, aluminium, copper, brass and other conductive metals using an electric arc and a jet of ionised gas. It can be used to shape sheet metal, trim sections, remove damaged parts and prepare components for welding. Applications include metal fabrication, machinery maintenance, automotive repairs and the production of brackets, frames or customised elements. As no blade comes into contact with the material, straight and curved paths can also be followed with relatively compact equipment.

At AgriEuro, machines can be selected according to their main technical features, making it easier to identify the configuration best suited to the metals being processed, the usual thicknesses and the frequency of work. The product data sheet for each model lists the parameters that should be compared before choosing.

• Cutting current: measured in amperes, it affects the machine’s ability to process materials of different thicknesses and must be adjusted to the metal;
• Cutting thickness: normally distinguishes a quality cut from the maximum severance thickness, which is achieved at a lower speed and with a rougher finish;
• Power supply: it must be compatible with the electrical network available in the workshop or on site, taking the required voltage and power consumption into account;
• Duty cycle: indicates how long the machine can operate within a defined period before it needs to cool down;
• Ignition system: it may require contact with the workpiece or use a pilot arc, which helps the cutting process start more consistently according to the torch configuration;
• Air pressure and flow rate: these must comply with the manufacturer’s specifications and remain stable throughout the cutting process;
• Torch and consumables: the electrode, nozzle, diffuser and retaining cap must be compatible with the model and inspected periodically;
• Size and portability: weight, handle and overall dimensions affect how easily the machine can be moved between the workbench and the job site.

For DIY work, ease of adjustment, compatibility with the available power supply and sufficient capacity for commonly used sheet metal are important factors. In semi-professional and professional settings, the duty cycle, consistent compressed-air delivery and availability of consumables carry greater weight. Selection should be based on the thickness processed most often, rather than considering only the occasional maximum value.

AgriEuro supports each purchase with dedicated delivery, maintenance and after-sales services. Its logistics centres and specialised after-sales service simplify every stage, from receiving the machine to finding compatible components.

• Fast and free delivery: shipping is coordinated directly by AgriEuro logistics centres, with procedures designed for handling technical equipment and reducing waiting times;
• Option to order spare parts: after purchase, the spare-parts diagram associated with the product can be consulted to identify the correct compatible components available;
• Attentive and personalised after-sales service: AgriEuro provides technical support for maintenance, spare parts and queries concerning the purchased machine, with coordinated service operations during the warranty period as well.

A plasma cutting machine creates an electric arc between the torch electrode and the workpiece connected to the earth clamp. The gas passing through the nozzle is ionised and converted into high-temperature plasma. The concentrated jet melts part of the metal and removes the molten material from the kerf. Current, travel speed, torch distance and air quality all directly affect edge consistency.

Plasma can cut electrically conductive materials, including carbon steel, stainless steel, aluminium, copper and brass. Actual cutting capacity varies according to the material, thickness, current and torch speed. Values stated for carbon steel should not automatically be applied to other alloys. The specific model data should therefore be checked when cutting aluminium, stainless steel and copper.

Selection should start with the thickness processed most frequently, not the thickest workpiece that might only be encountered occasionally. A higher current allows thicker sections to be processed but may require a more powerful electrical supply and higher air flow. The duty cycle should also be assessed: long, repeated jobs require longer operating intervals than occasional small tasks.

A quality cut produces a more even edge at a speed suitable for ordinary work and requires less subsequent finishing. Severance cut refers to the maximum thickness the machine can separate, often at a lower speed and with more dross or irregularities. The recommended cutting value should be used when selecting a machine, reserving the maximum rating for occasional operations.

Yes. If the machine does not include an integrated compressor, it must be connected to an external supply of clean, dry compressed air. The compressor must deliver the pressure and flow rate specified in the technical data even during cutting, not only when its tank is full. Many systems operate at around 5 bar, but the correct value always depends on the model. A separator filter helps retain condensation, oil and impurities that could damage the torch and consumables.

The duty cycle expresses the percentage of a standard interval during which the machine can cut at the stated current before cooling down. A 60% value over ten minutes, for example, corresponds to six minutes of operation and four minutes of rest under the conditions specified by the manufacturer. The percentage varies with the selected current and ambient temperature, so it should be read together with the other technical data.

The pilot arc starts the plasma before the main arc transfers to the workpiece. This solution supports consistent starts and, on compatible systems, makes it easier to work on painted, oxidised or discontinuous surfaces. Cutting metal grids requires a specifically compatible function, as the arc must restart when the torch moves from a metal section across a gap. This capability must be checked in the documentation for the individual machine.

Dross and irregularities may result from incorrect speed, unsuitable current, unstable pressure, damp air or worn consumables. A tilted torch or poor earth connection can also alter the kerf. If the jet deviates, ignition becomes unreliable or edge quality deteriorates, the nozzle and electrode should be inspected. Adjustments must follow the manufacturer’s table for the material and thickness concerned.

Routine maintenance includes inspecting the nozzle, electrode, diffuser and retaining cap. Components should be cleaned and replaced if they show deformation, erosion or deposits that affect the arc. Only consumables compatible with the torch specified by the manufacturer should be fitted. It is also useful to drain condensation from the compressor regularly and inspect the filter, cables, air fittings and earth clamp before starting work.

Plasma cutting requires eye, face, hand, body, hearing and respiratory protection selected according to the current and material. Suitable equipment includes a shield with the appropriate filter shade, welding gloves, spark-resistant clothing and closed safety footwear. The workstation must be ventilated and kept free from flammable substances. The machine manual and the safety procedures applicable to the working environment must also be consulted before operation.
