What Major Qualities Determine Which Is The Best Plasma Cutter?


The spread world of machinery and technical equipment is a confusing one, specifically when you want to purchase a machine that will work wonders for your business. With a plethora of plasma cutters available in the industry with different technical specifications and features, choosing the best plasma cutter can be a difficult experience. 

A plasma cutter can improve your fabrication skills with fine metal cuts, but a cheap quality plasma cutter ruined your work. We have put together a list of qualities that you need to look out for when buying a plasma cutting machine. Make sure you make an informed purchasing decision.

Major qualities to consider before investing in plasma cutter

  • Precise cut- One of the most important qualities that you need to look after is the average thickness of the metal that the selected plasma cutter can cut. Get enough information on the type and thickness of metals that the plasma cutter can precisely cut. However, an ideal quality plasma cutter can easily and accurately cut through any electrically conductive metal, i.e. stainless steel, alloy, aluminum, copper, and so on. All you need is to keep monitoring the thickness of the metal that the shortlisted cutter can cut through.
  • Power input- A decent plasma cutter that runs about 110/115/120 V power source is ideal for your indoor power supply source. Such a plasma cutter is the best option for beginners or those who are using it at home. However, if you want to use it for business purposes at a big level for heavy-weighted metals, then you will need to look for a 220V plasma cutter for the job to get done accurately. Before purchasing, make sure your workshop is compatible with 110V and 220V power outlets. 
  • Built-in air compressor– While cutting with a plasma cutter, there will be a need for compressed air to produce plasma. There are some plasma cutters available in the market that are already equipped with an air compressor or an external compressed supply. However, it can’t be overlooked that a plasma cutter with a built-in air compressor will be a little more expensive option, but worth the output you’ll get when using it on a daily basis.
  • Cutting speed- The cutting speed of the best plasma cutter is typically identified as Inches Per Minute (IPM). Your workflow and requirements will help you determine which cutting speed of the plasma cutter is the best for the job. One thing to know is that two plasma cutters can cut through a ½ inch of metal precisely, whereas one plasma cutter consumes one minute to cut the metal, while the other cutter could take as long as 4-5 due to low metal cutting speed. Choosing a plasma cutter with the right cutting speed can make a huge difference in your fabrication work and quality output.
  • Duty cycle- The duty cycle is the overall amount of time taken by the plasma cutter to operate its function (metal-cutting) within a ten-minute of time span before cooling down. A longer duty cycle will be an ideal choice for making deep or long metal cuts with utmost precision, while a shorter duty cycle is ideal if you’re working at home where a series of small metal cuts are required.

Last, but not least, it is ideal to test out the prospective plasma cutter or make sure the supplier offers a good return policy (specific cases) if the case cutter didn’t stand up to its commitments. Furthermore, a warranty period by the vendor also ensures your investment in the plasma cutter will be guarded for a longer duration.
