    Plasma Cutter Buying Guide

    Plasma cutters is an essential piece of kit for anyone that is cutting metal sheet. It effortlessly cuts through a wide range of thicknesses due to the large amount of heat that is generated by the unit. It uses an inverter that transforms AC to DC, which produces the electric car.

    Some units use an external air compressor whilst others have it integrated into the unit. Along with the input of air, other components required is a dedicated torch, cables and an earthing clamp.

    To help you make an informed buying decision, we have produced the below guide regarding plasma cutters.

    Built-in Air Compressor

    Not every plasma cutter will use a built-in air compressor, which make an external air compressor an essential piece of additional equipment.

    Those that have them integrated can be far more expensive but they are easier to use without the hassle of connected up any hoses.

    If you need to purchase a separate air compressor, you will want to ensure that it exceeds the recommended PSI in order to operate correctly.

    Voltage Input and Power Output

    If you are a beginner or simply want maximum convenience, you will want a 110V plasma cutter. They will plug straight into a normal power outlet and are ready to use. However, they will lack power when compared to the more powerful 220V units. These will only be compatible with welder generators or adapters but there are many dual voltage units available.

    The power output is measured in the amperage and the amount you require is determined by the thickness of the material. If you require more cutting power, you will require a higher amperage plasma cutter.

    For example, a 30A unit should be more than enough to cut through 3/8 inch, which many of the recommendations above state. High powered examples that are 80A and above are more than capable of cutting through 1 inch material with ease.

    Duty Cycle Rating

    All plasma cutters will come with a duty cycle rating, which describes the amount of time it can operate before needing to cool. It is a rating that is expressed as a % of time at a certain amperage. For example, the best plasma cutter (Hypertherm Powermax30) has a rating of 35% @ 30A. This means the unit can run for 3.5 minutes at 30A before needing to cool down.

    Depending upon the type of work that you will be carrying out with the plasma cutter will determine if this rating is an important factor.

    Portability

    If you intend to keep the plasma cutter inside the garage all the time, portable isn’t an issue. However, for those that take it from job to job, you will want to easily transport it on your own with limited hassle.

    Key points to check include an ergonomic handle that you can easily grip and the weight of the unit. Anything that is too bulky may be difficult to move and may be an issue. Although having an air compressor integrated into the unit will make it more convenient, it will increase the weight.

    Additional Equipment

    Unless you purchase the plasma cutter with a range of consumables, there will be additional equipment that you require. These include an electrode, nozzle, shield cap, retaining cap and swirl ring. These are all components that will need to be replaced as you begin using the plasma cutter.

    This is where the quality and clever technology comes into action because they help the consumables remain long lasting.

    Safety Recommendations

    Due to the large amount of smoke that is produced from using a plasma cutter, it is advised that you wear a welding helmet. You will want to have the best visibility whilst using the cutter to avoid incorrect cutting or injury.

    It is important that you also wear protective clothing that will protect you from sparks or droplets of metal. These include work shoes, aprons, welding gloves and more.

    Many manufacturers have integrated various safety functionality into the units. The main feature being thermostatic protection, which cuts of the supply of electric if there is a surge or voltage error. Other safety features include voltage signalling, overheating protection and high frequency priming of the pilot arc.

    Conclusion

    Plasma cutters are a versatile tool that can be used for a range of applications. Whether you are cutting up sheet metal for auto panels or taking on a roll cage project, they are an essential tool.

    All of our recommendations above are suited for professionals to those that are on a budget and want something easy to use. We highly recommend that you avoid cheap units unless they have long warranties or are developed by a reputable brand.
