CNC or automatic plasma cutting machines are being widely used in the fabrication industry and have become quite popular. Nevertheless, to get the best out of your CNC plasma cutting equipment, it is a good idea to follow some tips for efficient plasma cutting.
Before you begin operating your plasma cutter, familiarise yourself with the operation of the system by reading the instruction manual thoroughly. This will enable you to optimise the capabilities of your plasma cutting machine.
The plasma cutting machine must be maintained properly and must be operated in a dry, clean and an oil-free environment. The plasma cutter must be maintained at a specified pressure.
The plasma torch and the workpiece should be maintained at a vertical angle. When you begin cutting with the plasma cutter, ensure that the cutting begins at the edge of the plate and the plasma arc penetrates the workpiece fully. Ensure that the plasma torch is moving at the correct speed, not too slowly or too fast. After the cutting is completed, ensure that the plasma torch is disconnected completely.
Proper Operation of the Plasma Cutting Machine
Plasma cutting can be done using a cutting table. When using a cutting table, ensure that the plasma cutter starts cutting at the edge of the workpiece and do not begin by cutting a hole. Starting the cut from the edge will help to extend the consumable life. When cutting, avoid unnecessary arcing and reduce the arc time as prolonged arcing can cause electrode consumption and nozzle damage. Ensure that a proper distance is maintained between the plasma torch and the cutting surface. Make sure that the thickness of the material you are cutting is in the permissible range for the particular plasma cutting system.
The plasma cutting table, the plasma torch and all the consumables must be kept clean at all times as any dirt on the torch can affect the cut quality and efficiency of the system.
Reducing the Dross
When you are cutting with a plasma cutter, dross is produced. You must ensure that the plasma cutter has enough power to produce a sufficiently big plasma arc to melt the plate and so that the dross is also blown away. Make sure that the cutting speed and the speed of the gas flow is correct. If these are not right, there will be a greater accumulation of dross.
By keeping these tips in mind, you can optimise your plasma cutting, increase productivity, enhance efficiency and lower the operating costs of your business.
