  • How Thick Can a Plasma Cutter Cut?

    The cutting power of a plasma cutter will depend on its size as it relates to the amperage and voltage capacity. It is important to note that a plasma cutter requires a relatively high voltage and low amperage. So don’t determine the cutting power of a plasma cutter by its amperage alone.

    While amperage is important but what is more important is the total output power in terms of wattage. The wattage is a combination of amperage and voltage. For instance, if you have a machine with 12 amp and rated 110 volts.

    The total power out is 1,320 watts. This is able to cut through a metal thickness of 3/16” and 1/4 severance cut.

    Tips To Increase Cutting Performance With A Plasma Cutter

    A plasma cutter is an easy to use machine. But if you are looking to improve its performance, there are tips and techniques that can help youmake the most of the unit.Follow the instructions outlined to improve the performance of your plasma cutter.

    1. Have a good workstation –For a metalwork person, the workstation is his office. A good workstation helps the efficiency of your metalwork. As such, the workstation should be made convenient to easily carry out your metalwork job.

    Ensure that you have adequate tools. Make a comfortable work table with the right height to enable the easy use ofthe torch without any inconveniences.

    2.Make a nice metal for clamping –Having a good ground metal clamp helps to improve your cutting performance.Ensure you secure the clamp to a clean metal. Clamping goes beyond safety. It is more about cutting efficiency and performance. Avoid using rusted or painted metal as your ground clamp.

    This can affect the flow of electricity while working. Ensure the clamp is very close to the target cut path. Look out for loose spot or cable that may impede the ease ofelectrical flow.

    3. Get familiar with machine –Before you cut any metal, the first thing is to be familiar with the machine. Hands-on operationmakes youknow the functionality and deficiencies of the machine before you put it to use.

    Read the owner’s manual to know the workings of the unit. Knowing how the machine operates help you to work efficiently with the plasma cutter.

    4.Check the ground connection to the metal –It is true that a plasma cutter can cut through painted and rusted metal but it is important you ensure there is a proper connection to the clean part of the metal so as to have a good connection.

    5.Make the first sample cut – Don’t just start cutting straight up. Start with a sample cut.Testing the waters with sample cut makes the job easier for you.

    6.Set the right amperage –You need to set the right amperage for  every metal cutforeffective cutting.

    7.Brace yourself properly – When you are cutting a metal material, it is important to brace yourself. Use the other hand that you are not using to support the hand you are using to cut the metal.This helps to stabilize you when using the cutting hand with the other hand.

    8.Make the first cut –Everything depends on the first cut. A right first cut makes for a good flow of  easy cutting. Place the cutting tip of the torch on the metal before you pull the trigger. But if you are cutting a thick metal, it makes sense to start outside of the cut line.

    9.Be versatile –Versatility is important to be able to cut through different shades of metals. Mark out the areas you want to cut if you are dealing with very small cut. Take care of the bigger cuts first and cut the smaller ones by hand.

    How to Find the Best Plasma Cutter for Me?

    Finding the appropriate plasma cutter is not about ordering one online or picking one of the shelves. Your power source is a vital part of making a choice. A 220/240 volts power source makes the cutter to work powerfully. If you use 110 volts, the plasma cutter will work with less strength and power to deliver your tasks.

    Another important consideration is the duty cycle. The duty cycle is written on each plasma cutter. Duty cycle is all about the thickness of the metals you intend to cut. Plasma cutters with high amp will cut steel with 1/2″ thickness. If you intend to work on thinner metals, it makes sense to buy a lower amp plasma cutter.

    Below are the ratings for different amps and the steel thickness

    • 25 amp cuts 1/4″ steel thickness
    • 50 amp cuts 1/2” steel thickness
    • 75 amp cuts 3/4 steel thickness

    Ease of use is another worthy consideration. If you intend to move from one place to another, you would want something portable and lightweight. It also means considering a plasma cutter with dual voltage so you can easily alternate between the two voltages automatically. The plasma cutter should also be easy to set up with minimal difficulty.

    Finally, you would consider consumable life. It is clear that consumables with longer life help to reduce downtime when you are working. Look for consumables with a longer life. Many brands are compatible with your type of plasma cutter.

    About Plasma Cutting Thickness Range

    Thorough research is needed before buying a plasma cutter. The interest in price difference should not supersede the cutting ability of the machine.Aspects such as cutting speed, maximum cut size, machine features, CAM and CAD software are the most important considerations when buying a plasma cutter.

    Cut thickness ability is a vital considerable too. This consideration is what ensures that the cutter is able to cut the types of metal that you intend to cut.What you intend to cut is what determines the thickness of the material.

    How the machine cuts is also determined by the CAM and CAD software. The plasma torch that you use determines how thick the material you can cut.

    Using the Hypertherm Powermax65 for instance. The Powermax65 has a max pierce of 0.625” for mild steel, 0.500” for stainless steel and 0.750” for aluminium.

    So if you are buying the Powermax65, you must ensure that the steel thickness falls into the cutting capacity of the steels you want to cut. If it doesn’t, it means you need a higher unit.

    How hot is the plasma cutter?

    The plasma cutter is really hot. Never look into the flames directly because it can damage the eyes. Never try to put a finger into it. Don’t put it near your body too.

    The temperature is about 45,000 degrees Fahrenheit or 25,000 degrees Celsius.

    Its temperature is no where close to oxy-fuel welding machine which is around 9,000 degrees Fahrenheit or 5,000 degrees Celsius.

    The main reason the plasma cutter is perfect for cutting is because of the high amount of heat it is able to produce.

    You must understand that a plasma cutter consumes a lot of energy so your electricity bill is bound to go up. A plasma cutter is actually hotter than the sun.

    The average sun temperature is about 10,000 Fahrenheit.

    Compare that to 45,000 Fahrenheit of a plasma cutter and see that a plasma cutter is more than 4X the sun.

    The plasma cutter is also hotter than the core of the Earth. The warmest region on earth is about 11,000 degrees Fahrenheit. This is also 4X the temperature of the plasma cutter.
