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 possible through the use of Everlast Plasma Cutter that fuse a high-pressure air or gas flow with an electric arc. The heat can achieve 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 Above All
Even as plasma cutting is not as intense as welding, you must proceed as if it is. Ensure you wear flame-retardant clothes and hair protection. Put on glasses #5 eye protection and work in a secure area. Be familiar with your surroundings. Take note that the heat and light can be overpowering, and you need to ensure your safety.

Each time you notice that your cuts are losing their sharpness, you might need to change some or all of the components of the cutting head. In most cases, this would 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 some things you can do to delay the effects of moisture, and restrain 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. Get two, in fact - they are cheap. 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. See this video: https://www.youtube.com/watch?v=8Ofc_NS6o30.
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. If you cut too quickly, the sparks move towards you. Relax and slow it down. The sparks and dross should go towards the floor.
Often, you would hold the plasma cutter at 90-degree angle to what 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.
