What to know about choosing a plasma cutter

Whether you’re new to plasma cutting or want to upgrade your plasma cutter, we’ll lead you through everything you need to know to make a well-informed decision about purchasing a new plasma cutter.

1 | Select equipment based on the material you need to cut

Are you cutting mild steel, aluminum, stainless steel, or other materials? How dense? Mild steel is the most often cut substance, and as a result, mild steel is the most frequently rated fabric for plasma cutting equipment. Other conductive metals may also be cut using a plasma torch. People frequently use plasma cutting in auto repair, fabrication shops, industrial buildings, scrapping operations, and salvage.

2 | Choose the right plasma cutter for your transportation needs

A plasma cutter can weigh as little as 20 or 100 pounds for robust industrial units. You’ll need something you can carry without straining your back if you transport your plasma cutter from task to task. But keep in mind that smaller, heavier plasma cutters will be able to slice thicker metal than lighter devices.

3 | Examine the output power

The material thickness that a plasma cutter can cut depends on its output level (or amperage). You can usually determine the ideal range of thicknesses a plasma cutter can cut by looking at its amperage rating.

Verify that the fabric you intend to cut mostly falls within this thickness range. A general rule of thumb is that the more amperage you require to cut your fabric, the thicker it is. Choose a plasma cutter that is right for the job.

The model of plasma cutter you choose will depend on the type of work you do, much like when buying a welder. A plasma cutter can cut every type of metal except oxy-fuel cutting. The thickness and quantity of metal you intend to cut should therefore be your primary considerations when selecting a plasma cutter.

4 | Know your air supply capabilities and environment

Some brands offer better dependability in situations with significant amounts of dirt and metal shavings like those from grinding. Many hand-held plasma cutter companies advise utilizing regular air as the cutting gas for air supply. The cooling air passes through the equipment without blasting over the electronic parts, preventing the accumulation of grinding dirt on vital parts.

The machine reduces the quantity of debris entering the unit by only operating the cooling fan when necessary. Because it is less expensive than bottled air, builders frequently choose bottled nitrogen for smartphone platforms. Some think nitrogen creates less oxidation while cutting stainless steel than compressed air because it is drier.

5 | Buy from a verifiable source

Where you decide to buy plasma cutting equipment is just as significant as the model and brand that you select. Many manufacturers refuse to fulfill warranties for products bought outside official distribution channels. When making an online purchase, conduct your research to ensure that the vendor is reliable and available to help in case of a problem. Learn how to inspect used cutting equipment to ensure adequate functionality if you’re considering buying a plasma cutter, and ensure consumables and maintenance parts are still readily available.
