Understanding Tools

How to Use Plasma Cutters Safely and Effectively Plasma cutting is a valuable tool for producing fast, tidy cuts in steel, aluminum, or stainless. This is done through the use of plasma cutters that mix a high-pressure air or gas flow with an electric arc. The heat may go up to a temperature of up to 40,000 degrees Fahrenheit. The following are some things to keep in mind while you’re using a plasma cutter: First, Safety While plasma cutting is not as intense as welding, you have to proceed as though it is. Ensure you wear flame-retardant clothes and hair protection. Put on glasses #5 eye protection and work in a safe spot. Know your surroundings. Keep in mind that the heat and light can be strong, and you have to ensure your safety.

In case you notice that your cuts are losing their sharpness, you may have to replace some or all of the parts that compose the cutting head. Mostly, this will consist of a heat shield, contact tip, insulators, nozzle, and offset tool. It’s wise that you check the availability of the said consumables as you purchase your plasma cutter. Select a current model with a convenient process for ordering parts. The Importance of Moisture Plasma cutters need clean, dry air in order to function properly. Moisture is the biggest cause of parts going bad. There are a few things you can do to stall the effects of moisture, and restrict it to a bare minimum. Have 25 to 30 feet of line between the air compressor and the moisture trap. The moisture trap will work much with the air having a chance to cool first. Buy an air drier that makes use of silica gel to bring out moisture from the air. Have two in fact – they are inexpensive. These may be installed at the compressor, as well as at the water trap to prolong the life of your consumables. The air driers themselves are easier and less expensive to replace than the plasma cutter parts. Cutting Speed You must cut at the proper speed. If you’re new to plasma cutting, it might take you a number of tries to dialed it in properly. One of the surest indicators is the direction of the sparks as you cut. When you cut too fast, the sparks move towards you. You should take it slow. The sparks and dross should go towards the floor. The Angle Usually, you will be holding the plasma cutter at a 90-degree angle to whatever you are cutting. Upon reaching the end of a cut, shift the angle upward just a little to create a smooth end of cut. If you see some dross on the underside of your cut, a small file can take care of that.
