Buyer’s Guide: Find the Best Plasma Cutter for Your Needs


Plasma cutters are expensive, even those at the lower end of the quality-and-performance spectrum.

That said, you certainly don’t want to pay for a cutter that doesn’t meet your needs. But you also don’t want to pay a premium for features that you don’t need.

This buyer’s guide takes a look at the various buying considerations to consider when you’re looking for the best model for your specific needs.

Power

The power level you’ll need in a plasma cutter depends on the thickness of the materials you want to cut. If you’re generally cutting metals that are ¼-inch or thinner, you need a unit with a power output of at least 25 amps. If you want to cut metals up to ½-inch thick, you need a power output of at least 40 amps.

Heavy-duty plasma cutters capable of cutting 1-inch metals or more require outputs of 80 amps or more. Most models have variable power outputs that you can adjust according to the thickness of the metal you want to cut.

Duty Cycle

Manufacturers typically express the “duty cycle” of a plasma cutter as a percentage of time at a specific amperage.

This rating represents the amount of time in an hour that the cutter can operate without risking overload. For example, if a unit has a duty cycle of 50 percent at 40 amps, you can cut ½-inch metal for thirty minutes (50 percent of an hour) every hour without worrying about overheating.

Various factors influence the duty cycle. For example, manufacturers rate the duty cycle at room temperature, but if you work in a hot climate, your machine will have a lower duty cycle than listed in the specs.

The thickness of the metal you cut also plays a role. Cuts that require a power output of fewer than 30 amps require no cooling time.

Drag Technology

Drag technology is a feature that allows your torch to make smooth cuts through metal while the top of the torch touches the surface of the workpiece. If the cutter doesn’t feature drag technology, it may result in a double-arc fault, causing the nozzle to stick to the metal.

Problems with a double-arc fault include tip deterioration, loss of precision, and inconsistent cuts. Always choose a cutter with drag technology to avoid these issues.

Portability

Generally speaking, the higher the power output and functionality of a unit, the heavier and bigger it is. If you have to work at various sites, portability is a critical consideration. However, if you plan on placing your plasma cutter permanently in one location, don’t compromise on power for the sake of portability.

Pilot Arc Technology

Pilot arc technology makes it possible to cut expanded metals. If your plasma cutter features pilot arc technology, you can cut metals with corroded, dirty, or rusted surfaces. You can even cut metals that have a layer of paint on them.

High-frequency cutters, on the other hand, can only cut metal workpieces that have clean, plain surfaces.

In addition to making cuts easier on contaminated surfaces, pilot-arc technology also makes the plasma cutter safer to use.

Inches Per Minute

Inches per minute, together with a machine’s duty cycle, indicates the speed at which you can cut. For example, if a unit can cut ½-inch metal at a rate of 10 inches per minute, it will take you two minutes to cut up to 20 inches. If, on the other hand, the plasma cutter has a duty cycle of 20 percent, you have to wait eight minutes after cutting 20 inches before you can continue.

Consumables

Consumables are those plasma-cutter components that are susceptible to wear and, as such, that you must replace periodically. Consumables typically comprise a shield, retaining cap, nozzle, electrode, and swirl ring.

Look for plasma cutters that employ consumable efficiency and brands with affordable consumables to optimize your long-term savings.

External Air Compressor

A plasma cutter that doesn’t include an integrated air compressor requires an external compressor to pressurize shop air through the nozzle of its torch. Clean, pressurized air enhances the accuracy of your cuts and extends the life of your consumables. You also might need a filtration system to remove dust, oil, and moisture particles from the pressurized air.
