Plasma cutting is one of the most popular cutting methods for metal. Plasma cutter can cut through most metals and it is also easy to operate.
Plasma cutters use a high-velocity stream of ionized gas to cut through metal and other conductive materials. The gas is heated to such a high temperature that it ionizes or breaks down into ions. This process creates a plasma arc that is extremely hot – around 30,000 degrees Fahrenheit!- and very effective at cutting through metal.
But you might be wondering just how thick can a plasma cutter cut.
Many fabricators have concerns regarding their machine’s abilities to cut thicker materials like steel or concrete.
If you’re among them, this guide is written for you.
How Thick Can a Plasma Cutter Cut
Plasma cutter can cut both thin and thick materials. However, the thickness of the metal that a plasma cutter can cut through depends on several factors.
First, the power of the machine
Second, the type of metals you are cutting and
Third, the type of tip that is being used.
Some plasma cutters only can cut through thin metals, while others can cut through thick metals.
Each plasma cutter model has an optimal range of cutting thickness. A handheld plasma cutter can typically cut a steel plate thickened up to 38mm (1.5 inches).
If you need to do some heavy-duty cutting, you will want to look at machines with more power. An industrial CNC plasma cutter can cut up to 150mm (6 inches) thick steel.
If you’re planning to cut very thick metals, it is recommended that you go for an industrial-grade plasma cutter than a hobbyist model.
Industrial grade plasma cutters are more powerful and can cut through thicker metals like titanium and stainless steel. They also have better durability than hobbyist models and require less maintenance over time.
One thing to remember when using a plasma cutter is that the quality of the cuts will vary depending on the thickness of the material being cut. Thin materials like sheet metal will produce clean, precise cuts, while thicker materials may result in rougher edges.
However, a well-tuned plasma cutter can still produce reasonably clean cuts even with thicker materials.
Plasma Cutter Amps Vs. Thickness
If you’re in the market for a plasma cutter, you’ve probably seen a lot of information about amps and thickness.
But what do those numbers really mean? And how do you know which machine is right for your project?
The amperage of a plasma cutter is a measure of its cutting power. In general, the higher the amperage, the thicker the material a plasma cutter can cut. Most home and hobby models are in the 15 to the 40-amp range, while commercial cutters can be up to 200 amps.
If your project involves cutting mostly ¼-inch thick materials, a low amperage plasma cutter will be right for you. However, if you need regularly cut metals that are around ½-inch thick, you should go for a higher amperage plasma cutter.
