Plasma Cutters 101 – Buyer’s Guide

To understand what plasma cutting is and how it works, we first need to understand plasma as the fourth state of matter. In a nutshell, we get plasma when a gas is heated or subjected to a strong electromagnetic field, to produce an electrically conductive collection of highly charged negative electrons and positive ions.

A plasma cutter uses a highly compressed jet of hot plasma to cut through electrically conductive material. The process is fast, very precise, clean, and cheap, which makes it quite efficient and popular too.

Back in Time: A history of plasma cutters

Plasma cutting, developed by engineers of Union Carbide Corp, can be traced back to the 1960s. It was initially used to cut large stainless steel aluminum to smaller precise shapes. Back then, they were bulky, slow and expensive, and did not come with much flexibility.

 But as it is with technology, it kept evolving and improving until in 1968, when radial water injection was introduced. This nozzle technology worked by constricting the arc to increase energy density, leading to higher quality cuts within short spans of time.

Between 1970 and 1990, more cutting edge technologies were introduced with the aim of reducing power consumption of these plasma cutters while working at higher speeds.

It’s during this period that an oxygen based plasma cutting system was introduced. With this system, steel could be cut at lower power levels with high speeds and edge squareness was also improved.

The 90s Era to the current generation saw the discovery of high definition plasma, among other technologies which all worked at reducing the price of plasma cutting, increasing energy density, minimizing errors and automating processes.

 Computer Aided Design has since taken over and operators now use CNC machining in large scale production which requires a high level of precision and speed.

Types of Plasma Cutting Machines

Plasma cutters can be broadly classified into two groups namely:

  • Conventional Plasma systems

Conventional plasma cutters are used in small scale settings to cut steel or metals that do not require high amps. They are mainly hand-held plasma torches that are easily maneuverable with power ratings that range from a low of 7 amps to a high of 200 amps. They don’t need additional air and their input voltage ranges from 120 to 600.

  • Precision Plasma Systems

They are specifically designed to produce high precision cuts of the highest quality. They use compressed air and operate with amperage ranging from 100 to 600. They are powered by three phase power transmissions with an input voltage ranging from 200 to 600.

Businesses Making Use of Plasma Cutters

  • HVAC Businesses: in duct cutting it helps to achieve precise cuts and replicate parts remarkably fast.
  • Construction: Many construction projects which involve cutting of brackets, fencing, brace plates to name but a few have benefited from plasma cutting.
  • Art: artists using metal in their venture can now create innovative metal designs, signage, and templates thanks to CNC Plasma Cutting technology.
  • Automotive Businesses: this is one industry that saw a great need for customizing automotive be it for vehicles or tractors, and has certainly benefited from plasma cutting technology.
  • Energy Industry: the need for fabrication of components of equipments and devices used in this industry such as filter separators, electrical boxes and switches e.t.c. has seen to the rise of wide use of plasma cutting in the energy sector.

Top Brands in the Market

  • Lotos dominates the space in terms of pocket friendly pricing, basic yet reliable features, and the easy access to its consumables. They are great performers with most of them featuring a pilot arc for precision cuts among other model-specific features.  
  • Hypertherm on the other hand presents robust units which you can depend on to give you some years of service. These units are designed for both light and heavy duty plasma cutting yet they feature diversity in their operation and the kind of simplicity that beginners looking for a quality start will appreciate. Both the LOTOS and the HYPERTHERM brands are keen on performance albeit at different levels.

What should you consider Before Selecting a Plasma Cutter?

With so many plasma cutting models available, selecting the best is no easy task. There are a lot of things you need to evaluate including:

  • Max cutting thickness – The first factor you must always look at is its ability to cut through your preferred thickness. You will most likely see them labeled max severance thickness ¾ inches and max cutting thickness ½ inches. You get to choose what suits you which and this is a factor that greatly influences price.
  • Cooling systemFor your machine to run effortlessly and serve you longer, it requires a cooling system, to prevent the electrode and nozzle from melting. The best Plasma cutters will come with a built-in cooler to automatically cool .
  • Cutting Speed and Duty Cyclecutting speed is a critical factor particularly in commercial settings. For a plasma cutter, the cutting speed is measured in inches per minute (IPM). The higher the amperage of your cutter the faster it will cut. It is advisable to get a cutter that can tackle twice the thickness of the application you intend to put it into. Duty cycle on the other hand defines
  • BevelBevel results from motion of plasma gas produced from the nozzle. When buying a plasma cutting machine, look for one with a torch that provides quality cuts and in straight lines.
  • TorchPlasma torch sometimes referred to ask the arc is responsible for the direct flow of plasma. The cutters come with a torch and some are even customizable to one’s liking.
  • VoltageMost plasma machines operate with either 100v or 220v. If you are not sure which voltage you need, there are dual voltage plasma cutters.
  • WarrantyTo avoid getting stranded in case of any sudden or future faults, you need to check the warranty period.  Never accept a plasma cutter or any other machine for that matter that does not include a warranty.

CNC cutting methods

It is almost impossible to make precise cuts on metal when doing it manually. With the help of a computerized system, metal cutting machines can cut out various shapes and sizes accurately and fast all thanks to CNC (Computerized numerical control). In metal cutting, there are 6 CNC methods you can use. They include:-

  • Plasma cutting– Best for thick metals as it involves high temperature plasma and electric arc.
  • Laser Cutting– Cuts through metal pieces less than one inch thickness by vaporizing them with.
  • Water jet cutting– It is the slowest of the previous mentioned as it uses high pressurized water to cut metal as thick as 6 inches.
  • Oxy Fuel cutting
  • Surface Grinding– It involves a spinning disk to make flat surfaces in metal pieces. This is made possible by the coarseness and abrasive grit that covers it.
  • Cylindrical Grinding– It combines lathe turning and surface grinding to make cuts on both internal and external diameters.

Maintenance tips

Every machine requires some level of maintenance for continued performance and longevity. Some measures to take include:-

  • Clean your plasma cutter frequently as it is subject to dust and debris which can clog the hose. To do this, a blower is most suitable to get the job well done.
  • Perform regular check-ups on the hose. This should be done to avoid any future malfunctions.
  • Replace consumable parts frequently.
  • Avoid arc stretching as this could easily wear off the consumables.
  • Ensure gas and coolant flows are consistent which again promotes durability of consumables.
  • Assemble torch parts as required and clean the body and leads routinely. Additionally, do not use it as a hammer.

Safety Tips

  • Eye damage (arc eye) is likely if one doesn’t wear eye protection.  It is necessary to wear appropriate lenses to protect your eyes from ultraviolet and infrared light. For skin protection, wear protective clothing such as insulated gloves and industrial boots.
  • Fumes from metals, if not toxic may lead to health issues such as lung damage, crippling of the nervous system or certain types of cancer with continued exposure. Invest in an appropriate respirator.
  • Magnetic fields from plasma cutters affect the functioning of the Pacemaker and hearing aids. Wearers should consult a physician before going to such sites.
  • Extreme caution needs to be taken to avoid plasma arc burns which can be inflicted through plasma arc rays.
  • Never touch any part of the plasma system of operation as this may lead to fatal electrical shocks. This is where insulated gloves come in.
  • Never use compressed gas equipment that are not designed for that specific purpose.
  • Some plasma cutters produce a lot of noise. Always wear ear protection.

Accessories/ Safety Accessories

To protect you and your cutting machine, there are safety accessories that you need to purchase along with it. They include:

  • Machines cover This keeps off dust and also prevents it from rusting.
  • Plasma Roller Guides when cutting along fine lines, you need a plasma roller guide to help keep the torch steady for a straight cut.
  • Welding jacket It should be both protective and comfortable to work in.
  • Gloves They keep your hands safe from the spark, heat, and spatter. They should be well fitting and comfortable.
  • Helmet It should have the ability to purify your respirator system since you are going to work in a harsh environment.
  • Safety glasses- They protect your eyes from the arc rays. These should be high-quality and well fitting.
  • Pressurized air for plasma cutters that depend on shop air This is very important as it aids in accurate cuts as well as extending the life of other replaceable parts.
  • Circle cutting attachment- It is an accessory that aids in making clean and accurate cuts.
  • Consumables this is a replacement kit that includes spare parts of the cutter which wear out fast.

Frequently asked questions
