Hypertherm plasma cutters are a must-have for anyone in the fabrication field. However, as amazing as these tools are, they are not without their limitations. Understanding what your plasma cutter can and can’t do will go a long way in helping you get the most out of it.

For instance, will your plasma cutter cut rusty metal? In this post, we’ll offer a quick breakdown of the types of materials your plasma cutter can cut.

How Do Plasma Cutters Work?

The first step to understanding your plasma cutter’s limitation is knowing how it works. Basically, a plasma cutting machine is a tool that uses ionized plasma to cut through metal.

It has two main parts: a power supply and a torch. The power supply provides the electrical current that ionizes the plasma gas. The torch then directs the ionized gas towards the metal you intend to cut.

All plasma cutters fall under two major categories – conventional and precision plasma systems. Conventional systems use the torch’s nozzle to determine the shape of the pilot arc. Precision systems on the other hand use various gases to deliver optimal cuts.

The Benefits of Using Plasma Cutters

Yes, you can use other tools to cut your metal, such as oxy-fuel torches and saws. However, plasma cutters have a distinct advantage.

For starters, plasma cutters are a lot more precise. They enable you to create that clean cut you desire. If that wasn’t enough, they are also less likely to harm the material around the cut. This makes them the perfect option when cutting metal in tight spaces.

What Can Plasma Cutters Cut?

Will your plasma cutter cut rusty metal? The short answer is yes. In fact, your plasma cutter can cut through most metals whether they are painted or rusty. This is why many people in the construction and automotive industries prefer using them.

What You Cannot Use Plasma Cutters On

Sadly, your plasma cutter can only do so much. Yes, it can cut through rusty or painted metal, but it still has its limitations.

This should go without saying but your plasma cutter cannot cut through non-metallic materials such as glass or concrete. Also, it won’t be able to cut through coated metals like galvanized steel.

Such materials prevent the plasma from ionizing. Since this is what’s responsible for creating the clean cut you desire, using your plasma cutter on powder-coated metals will only be a waste of time.
