A plasma cutter amps thickness chart is an invaluable tool for anyone working with metal. It provides concise, accurate information about the thickness of different metals which can be cut using a particular plasma cutter amp rating. This chart is particularly useful for welding and fabrication projects as it helps to ensure that the right level of cutting power is used for the job at hand.
Here are the top plasma cutters with built-in air compressors.
How AMPs affect plasma cutting?
AMPS (Ampere) affects plasma cutting by controlling the speed and depth at which the plasma cutter cuts metal. For example, a lower AMP rating will provide a slower cutting speed and a shallower cut, while a higher AMP will result in a faster cutting speed and a deeper cut.
Case Study 1: A manufacturing company was using a plasma cutter with a fixed amperage setting of 40 amps. They found that the speed of the cut was too slow and the quality of the cut was not up to their standards. After increasing the amperage to 60 amps, they found that the speed of the cut increased and the quality of the cut improved.
Learning Outcome: Increasing the amperage of a plasma cutter can improve the speed and quality of the cut.
Case Study 2: A fabrication shop was using a plasma cutter with a fixed amperage setting of 70 amps. They found that the heat generated during the cutting process was too high and was melting the edges of the material they were cutting. After decreasing the amperage to 50 amps, they found that the heat generated was reduced and the edges of the material remained intact.
Learning Outcome: Reducing the amperage of a plasma cutter can reduce the amount of heat generated during the cutting process.
Here are the Plasma cutting tips written by the experts.
How metal thickness affects plasma cutting?
Metal thickness affects plasma cutters in two primary ways: power output and speed. The thicker the material, the higher the power output and slower the speed required to achieve a successful cut.
For example, a plasma cutter with a power output of 30 amps is suitable for cutting material up to 1/4 inch thick. As the thickness of the material increases, the power output required will also increase. For example, a plasma cutter with a power output of 50 amps is typically required to cut material up to 1/2 inch thick.
The speed of the plasma cutter will also need to be adjusted based on the thickness of the material. For thin materials such as sheet metal, a faster speed is usually required to achieve a smooth cut. On the other hand, thicker materials require a slower speed to ensure a clean cut.
In general, it is recommended to set the plasma cutter’s power output and speed based on the thickness of the material. For example, if you are cutting 1/4 inch thick material, you should set the power output to 30 amps and the speed to a medium setting. For 1/2 inch thick material, you should set the power output to 50 amps and the speed to a slow setting.
How does the cut chart contribute to plasma cutting?
Cut charts are diagrams that provide information about a particular type of plasma-cutting process. They provide information on the best settings to use when cutting a particular material, such as the recommended cutting speed, amperage, and torch–to–work distance. Cut charts can help to ensure that the plasma cutting process is as efficient as possible and that the best quality cut is achieved.
For example, if a user wants to cut a piece of stainless steel, the cut chart will provide information on the best settings to use. It might recommend a cutting speed of 150 IPM, a current of 100 amps, and a torch–to–work distance of 1/4 inch. By following the recommendations on the cut chart, the user can ensure that the plasma cutter will function properly and deliver a good quality cut.
Another example is when a user wants to cut a piece of aluminum. The cut chart will provide specific information on the settings to use when cutting aluminum. It might recommend a cutting speed of 200 IPM, a current of 75 amps, and a torch–to–work distance of 1/8 inch. By following the recommendations on the cut chart, the user can make sure that the aluminum is cut with the best quality and efficiency.
What does our AMPs & Thickness Cut chart include?
A plasma cutter CUT chart includes information on the settings and parameters that should be used when cutting different types of metals. This includes the amperage settings and the cutting speed that should be used for different metals and thicknesses. This information assists in metal cutting by providing guidance on what settings should be used to achieve the best quality cut. It also helps to ensure that the cutting process is safe and efficient.
