Plasma Cutter Best for Workshops

Plasma cutting is now one of the fastest-growing steel cutting practices among the diy  homeowners, repair and restoration shops and even in large scale metal production industries.plasma cutter best

Unlike with oxy-fuel cutters that cut metal by oxidizing and burning it, plasma cutters can almost cut any type of metal by melting it as long as it is conductive to electricity.

There are 3 different types of plasma cutters.

There are the 3-phase units like the CNC types that require high-frequency current and used generally in industrial settings,

the mid-range machines that are capable of TIG or MIG or Stick welding and the cheap plasma cutters that are mainly for cutting metals and suited for the hobbyists and DIY guys.

If you are looking for a plasma cutter for your home use, the budget plasma cutters are right for workshop use. However, most of them are best only for metal cutting and have limited cutting capabilities with regards to metal thickness.

The mid-range plasma cutters are for the multitasker because they offer more features like TIG, MIG or Stick welding.

These cutters are in general more expensive than the cheap plasma cutters. But they can compensate you with better quality cuts and more versatile use. But don’t get us wrong. There are also cheap plasma cutters under 500 that are also versatile, have a high-duty cycle, and robust in their plasma cutterconstruction.

So if you are into a serious metal work which means you have to have the best plasma cutter and a welder in one unit, you can settle for the mid-range plasma cutters that can do various types of welding.best plasma cutter under 500

Before we go looking for the best plasma cutter suited for multi-tasking jobs and do the plasma cutter reviews, let us first identify what should you consider when choosing the best plasma cutter suited for your workshop.

Practical Tips When Buying a Plasma Cutter Best for Workshops

Consider the thickness of the metal you will most likely to cut. Low amperage units are best for thinner metal sheets while higher amperage are perfect for thick metals. For example, 80 amperes can cut up to 0.75-inch thick metal, 60 amperes can cut 0.5 inch and 25 amperes for 0.25 thickness.plasma cutter best

Prefer those that have fastest cutting speed. Speed is measured in inches per minute (IPM). Since higher amperage units can cut faster than lower amperage units, prefer the best plasma cutter that has twice the cutting power as against the thickness of the metal you want to cut.plasma cutter best For example, 60 Amps plasma cutter can cut a .25-inch metal twice faster than a 25 Amp plasma cutter.

Consider the Duty Cycle. Mid-range and budget plasma cutters generally have a duty cycle of 10 minutes which means you cannot use the torch continuously for more than 10 minutes or the machine can overheat. That’s why some manufacturers indicate in their machines the duty cycle in percentage. For example, a 40% duty cycle means you can cut continuously for 4 minutes but have to rest the machine for 6 minutes.

Check the portability features. You may want to consider mobility or portability. If you are looking for a plasma cutter best for workshops and to bring to your job site, it should be easy and light to carry and can be hooked up on standard electric outlet. You can find such machines that have adapted the inverter technology.plasma cutter best

Availability of consumables. Make sure your unit has a lot of available consumables that could match its accessories and easily available for order. Take note that some brands are very specific with their consumables. That’s why a plasma cutter that requires generic plasma cutter consumables including TIG and MIG consumables should be on your priority list.

If you are on a budget and only need a metal cutter for your workshop, the cheap plasma cutters can be the right units for you. But if you wanted to take plasma cutting to the next level, we recommend the mid-range units.

Their price ranges from US$500 but should not be over US$1000. As we have said, they are a bit more expensive than the budget types but these are packed with additional features and have more useful functionalities.plasma cutter best

So here are some of our plasma cutter reviews and we’ll focus on the mid-range units.

Best Plasma Cutter for Home Workshops

This plasma cutter uses the blowback system which means the electrode is pushed back to let the air pressure to pass thru the nozzle to create a spark and eventually form an arc between the nozzle and the base metal. In this process, a low amperage arc is formed.plasma cutter best

The advantage of a blowback feature is that it doesn’t require the High Frequency to start up an arc which can interfere with the electronics connected to the wires. It also enables the arc to cut on painted and rusty metal without the need to tap the nozzle torch to the base metal.plasma cutter best

This unit can also be used with generators with up to 11,000 Watts to get clean power. It is also equipped with IGBT (inverter) modules from Infineon which makes the unit lighter, more portable and yet high performing in all aspects. So not only that this small machine is perfect for home workshops but it can also be your best plasma cutter if you are running a fabrication shop.

This machine can deal with metals up to ¾ inch thick at high speed. It is also capable for 1-inch thick to 1 and ¼ inch severance cut. It can virtually cut almost any type of metal like stainless, steel, copper, aluminum, nickel, nickel alloys, cast iron, and even titanium.plasma cutter best

So how does this differ from the 50 amps unit that the DIY users prefer? Well, this unit has a 60% duty cycle at 60 amps so it’s actually a CNC capable unit. It can cut cleanly and smoothly using a genuine iPTM 60 CNC torch.

So this is a hard-core, heavy-duty unit that is capable of industrial use but should be perfect for home workshops without disrupting the flow of current.

For its price that is less than US$1000, this machine can be your good investment especially if you’ll use it for restoration shop and even for your metal assembly shop.
