The Best Plasma Cutter Buying Guide: How to Select Your Plasma Cutter

A plasma cutter will slice off almost all kinds of metals within minutes. But you need to purposefully select the best one for the cuts. Once you go through this elaborative buying guide section, you will know which factors you must consider for the plasma cutter. 

 

Power Source

Commonly a plasma cutter will use either electricity or air pressure to cut through metals. Truly speaking, both are powerful and will provide you utmost satisfaction.

You only need to pick which one fits your workspace requirement. Pick the electrical one if you have access to circuits or go for the air pressure powered cutters. 

 

Cutting Thickness 

The only function of the plasma cutter is to slice through metals. So, the cutting thickness will play a key role when it comes to selection. 

The cutting capacity is linked with the cutter’s plate thickness. In general, most plasma cutters can cut 3/8” thick aluminum and 5/8” thick steel plates. And almost every cutter will cut stainless steel up to ½” depth. 

 

Duty Cycle 

The duty cycle determines the running capacity of the plasma cutter without any damage. It depends solely on the motor amperage. You should find the duty cycle percentage on the product label. 

Ideally, most plasma cutters have a 60% duty cycle for 110V and around 35% for the 220V operations. However, this will vary with the models. So, check the duty cycle when you go to buy the plasma cutter. 

 

Cutting Speed and Quality 

Most welders often undermine the cutting quality and finish when it comes to picking the best plasma cutters. We discourage such practices. 

When you buy, check for the finish quality. Remember that with higher amperage, you will get a better finish. The lower amperage will provide uneven finishes. Also, the cutting quality will be a direct output of the cutting speed.

Most plasma cutters will feature variable speeds suitable for different metals. It helps you finish the cuts faster and with the optimal quality. 

 

Torch Type

The torch of the plasma cutter facilitates you to slice through metal with heat generation. You may find three types of torch suitable for plasma cutters. These are:

  • Lead torch: The lead connects the torch with the machine.  For stationary cuts, you should use a longer lead, and for moving machines, even shorter leads will do easily. 
  • Non-touch torch: As the name suggests, with this torch, you won’t have to touch the metal for cutting.  Plasma cutters with non-touch torch provide a smooth finish, and the nozzle also remains clean. 
  • Drag torch: This kind of torch will touch the metals, and as you drag the machine, it will slice through the metal. Drag torches are suitable for decorative cuts on metals.
