How to Choose The Right One?

Following are the factors you need to consider while choosing a plasma cutter:

Type of Plasma Cutting

On which surface are you going to use the cutter: table or floor? If you are unsure about the future, get a plasma cutter which offers both. That’s right; there are cutters out there who let you switch between handheld and mechanized modes, and back again.

Or, if you can afford to spend extra, there’s nothing better than a CNC plasma cutter. They rely on a computer to control the path of the torch, with the term CNC referring to “Computer Numerical Control.” And the best part about them? They provide accuracy and quality for all types of metal fabrication.

Cut Rating

The cut rating determines the cutting speed of a plasma cutter w.r.t. The thickness of the metal it is dealing with. At the cost of over-generalization – since most manufacturers have their names for cut ratings – here are the three most common cut ratings out there:

  • Rated Cut:

Cuts mild metal has a cutting speed of 10 inches per minute.

  • Quality Cut:

Cuts thicker materials and has a lower cutting speed.

  • Sever Cut:

Can cut through the thickest of metals, though the cutting speed is less.

Pilot Arc vs High-Frequency Plasma Cutters

Once you’ve chosen between a handheld and CNC plasma cutter, the next stage involves choosing between these two.

  • Pilot Arc

Pilot arc operate on the principle that your interfere with electronics should be as less as possible when the cutter is doing its job. Unlike high-frequency plasma cutters, they do not undergo a scratch start – which is the reason why they last longer. Finally, they have ridiculously low running costs.

  • High-Frequency 

Go to your nearby fabrication shop, and 9/10 times you’ll come across a high-frequency plasma cutter. In addition to being cheaper – hence the reason why they are so ubiquitous – the high-frequency cutters produce a stable cutting arc. Since they undergo a scratch start, these cutters have a lower shelf life.

Other features

Regardless of your project type, you must look for these features before making a purchase:

  • Duty Cycle

Want to meet output quotas? Have a huge order to fulfil? Then get a plasma cutter with a high duty cycle – which determines the time your cutter can run continuously without requiring a shutdown. Put, if your cutter’s duty rating is 50%, it might only operate for 5 minutes out of 19 minutes total.

  • Cut Quality

Looking for the cleanest cuts out there? One way to make sure of that is getting a cutter which offers continuous plasma arc. By cutting in a non-disrupted way, it provides a uniform and clean cutting quality. Also, if you can, get MOSFET transistors in your machine as they also help to create a steady arc.


Read the above mentioned reviews carefully? If your answer to the question isn’t in the affirmative – which means you need our recommendation – our vote goes in favor of the  Lotos LTP5000D 50Amp. Though slightly expensive, this plasma cutter packs a brilliant bunch by offering a market-high duty cycle, excellent cut thickness, and uniform cut quality. Add to this its warranty of 1-year, and this plasma cutter becomes a must-have.
