What is a Plasma Cutter Duty Cycle? Brief Guide [2021]

Plasma Cutter Duty Cycle

The plasma cutter duty cycle of a specific device is the period in one hour that the cutter may safely operate with no flashlight or device overheating or shutting down.

Plasma Cutter Duty Cycle

This is usually expressed as a percentage and can be set by how much amperage the device pulls. Let’s say that the plasma cutter you’re taking a look at is your Hypertherm Powermax 45 plus it’s after duty cycle values: When creating a mean cut, a half-inch thick alloy that needs 45 amps of electricity, this Hypertherm plasma cutter can operate for approximately 30 minutes every hour without overheating (50 percent of one hour).

 In the same way, it may make cuts requiring 41 amps for 36 minutes from each hour (60 percent of the hour). Finally, for reductions requiring 32 amps or not, this device needs no heating time. Make sure to take a look at your producer’s cut guides for suitable amp requirements so that you may evaluate the duty cycle properly).

Why is Duty Cycle important?

The significance of a duty cycle depends on how you will use your plasma cutter. Ask yourself: “What kinds of jobs will I’m using my plasma cutter for and also the depth of alloys I shall generally be cutting and where would I’m cutting” Generally, a more significant or more duty cycle includes bigger power requirements along with a more substantial cost.

If you’re performing lengthy, time-consuming cuts or are trimming in an automatic setup like a CNC kind of installation, starting/stopping or downtime is expensive. If you’re searching for a plasma cutter in the manufacturing shop, you may demand a duty cycle of 50 percent or greater for manufacturing purposes.

Therefore a plasma cutter having a more significant percentage at more excellent amps will signify that you’re putting more and, consequently, making money and also have less idle time. But if you are using your plasma cutter for briefer lengths of time, like on small tasks, artistic tasks, or only overall cutting-edge, the duty cycle could be necessary for your demands.

If you’re a home user or an occasional person, you could quickly get by using a version that has a 35% duty cycle in the same rated output. Besides, the plasma cutter duty cycle is based around a specified speed of clipping. The manufacturer generally provides cutting rates for many thicknesses of alloys. This is quantified in IPM (inches per second). Suppose the alloy you cut frequently is stated 1/4″.

 In that case, a machine that delivers a greater amperage will have the ability to cut the alloy considerably quicker than one graded at a lower amperage, but both may do the job. A fantastic guideline is to pick a machine for manufacturing cutting, which could handle roughly twice your regular cutting edge thickness.

There’s yet another essential aspect to consider for the duty cycle that many do not talk about–surrounding temperature. A duty cycle is generally given for this device’s highest output signal (usually at 104F (40C). The ambient temperatures can affect the duty cycle.

The device has a rated duty cycle of 75F (24C). It won’t conduct the same portion with all the temp at 95F (35C). On the other hand, the inverse can be true because it might operate somewhat longer if working outside at 40F (4C).

Final Words

Therefore the plasma cutter duty cycle is the quantity of time in one hour that the cutter may safely operate. Knowing how you will use your knife regarding the duty cycle is crucial since, if you go on your duty cycle, you risk damage to a plasma cutter, or you also get to have a rest while the cutter melts down.
