How to Choose the Right Plasma Cutter?

Need the fastest way to cut the thickened metal objects? How to Choose the Right Plasma Cutter? A plasma cutter works by an inert gas passing through the metal objects and a sparking electrical arc at the same time to perform its massive  cutting tasks.

Buying a plasma cutter is a hefty investment as this is a powerful hardware machine that uses much power to work. In order to secure your investment, you need to consider few factors while choosing the right plasma cutter for your projects. No need to worry as we’ve got you covered with all the knowledge you need before opting for the best plasma cutter. Let’s start the guide.

Tips for buying the best plasma cutter:

First things first, let’s discuss the right kind of plasma cutter you need. The choice of a plasma cutter will depend on cutting work and metal projects. For example, in the case of oxy-fuel cutting, the plasma cutter can cut every kind of metal object. Some others in the same category are only able to cut specific types of metal objects. Here is some question you need to ask yourself before opting for a plasma cutter.

  • How thick metal you’re working on?
  • Is this a regular job or not?
  • What kind of plasma cutter do you need in terms of power?
  • Do you want portability or not?

Once you’re done with the type of plasma cutter, then it’s time to get to the next step.

Efficiency and Output-Plasma Cutter’s Power:

The next thing to look into a plasma cutter is its efficiency and power yield. The plasma cutter comes in a variety of power options which you can choose depending on the type of work.

For example, if you need to cut the 1/8-inches of the metal piece, then you need a plasma cutter with a power of 12 amps. Meanwhile, if you’re looking for a rugged machine that can cut 7/8 inches of metal objects as well, you may opt for 60 amps powering from a 230V of plasma acuter.

Speed and Accuracy:

The cutter’s speed will decide how much time and clean-cut you’re going to have with a specific plasma cutter. The cutting speed has a unit of Inches per Minute (IPM).

For example, if you have a plasma cutter with low RPM, it might take 4 or 5 minutes to cut a specific width of a metal object while the other on with higher RPMs will take only 1 minute or so. Therefore, choosing a particular type of cutting speed will impact efficiency.

Plasma Torch:

The last but not the least factor to look at is the plasma torch. Two types of plasma torches come in these plasma cutters. The one with a higher frequency is better to work with but requires higher voltage and vice versa.
