Buyer's Guide: How to Pick the Plasma Cutter
With a plasma cutter, you can slice through almost any type of metal, including those used on vehicles. With our buyer's guide for plasma cutters, you can see what features are the most important before buying the best one.
Plasma cutters can use either air pressure or electricity to cut through metals. Both are equally strong and suitable for most applications, but you may find that one is better for where you work.
If you rarely have access to electrical outlets, you'll want an air pressure model. No matter what cutter you choose, you should also consider the type of gas that it needs to run too.
With electric cutters, you should choose one with dual voltage options because you won't always have access to the same outlets. With these models, you can use both 110V and 220V standard power sources. Some plasma cutters come with adapters that let you change the plug to use different outlets.
Depending on the thickness of the materials and metals that you use, you may want to check the plate thickness of the plasma cutter. This refers to the maximum thickness that the machine can cut through.
You'll generally find that most have a plate thickness of up to 3/8-inch when working with aluminum. This means that you can also cut through steel plates of up to 5/8-inch thick and stainless steel plates with a thickness of 1/2-inch.
The duty cycle tells you how long you can use a plasma cutter without risking your safety. This usually depends on the amperage of the welder and appears on the box in a percentage format.
A plasma cutter with a lower duty cycle can only run for a few minutes, but one with a high duty cycle can run for a longer period. If you work with thicker metal, you need one with a longer duty cycle. This ensures that you can finish the job without the cutter overheating.
One thing you may not think about when choosing a plasma cutter is the quality of the cut. The machines that have the highest amperage settings typically produce better cuts. At a lower amperage, the cutter needs to expel more force to make the cuts, which can result in jagged or uneven edges.
The quality of the cut is important because it can help you complete jobs faster. If you have uneven or jagged edges, you may need to go over the edges with a sander to buff them out.
Plasma cutters often have more than one cutting speed, which lets you select the speed that works best for your project. With a higher speed, you can cut through the metal in one pass as long as you stick to the maximum thickness. At a lower speed, you will need to go over the metal more than once.
Keep in mind that the cutting speed can relate to the duty cycle too. A machine with a five-minute duty cycle will need to shut down and cool for five minutes before you can use it again.
