Pointers for Safe and Effective Use of Plasma Cutters Plasma cutting is a precious tool for getting fast, neat cuts in steel, aluminum, or stainless. This is possible through the use of plasma cutters that fuse a high-pressure air or gas flow with an electric arc. The heat could get 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: Safety is Priority Even as plasma cutting is not as intense as welding, you must proceed as if it is. Make it a point to wear flame-retardant clothes and hair covering. Put on glasses #5 eye protection and work in a safe spot. Know your environment. Remember that the heat and light can be great, and you should ensure your safety.
What Research About Equipment Can Teach You
Equipment – Getting Started & Next Steps
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 require clean, dry air to operate well. Moisture is the biggest cause of parts going bad. There are some things you can do to decelerate the effects of moisture, and control 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 more efficiently if the air has an opportunity to cool first. You can buy an air drier that uses silica gel to pull moisture from the air. In fact, get two – they are affordable. These could be installed at the compressor and at the water trap to stretch the life of your consumables. The air driers themselves are easier and less expensive to replace than the plasma cutter parts. Cutting Speed You should cut at the effective 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 have to slow it down. The sparks and dross have to head towards the floor. The Angle Usually, you will be holding the plasma cutter at a 90-degree angle to whatever you are cutting. Reaching the end of a cut, pull the angle up a bit to make for a beautifully smooth end of cut. If there’s some dross on your cut’s underside, a small file should take care of that pretty well.
