Designed to cut through the thickest and toughest metals, plasma cutters are best suited for machine shops and heavy-duty construction. They rapidly heat up with compressed air or gas, and the arc torch is capable of reaching extremely hot temperatures. The small flame is then able to make a clean cut through tough metal and steel with ease. If you have a difficult job ahead of you and need a high-quality plasma cutter, consider one of these for your workshop.

Tips

  • Make sure the power source you are plugging the plasma cutter into can handle the machine. If not, you may end up tripping a breaker and shutting off the power.
  • Wear protective eyewear to avoid any slag or other debris from getting in your eyes.
  • Always wear a thick pair of gloves when operating the cutter. They will ensure your hands don’t get dangerously burned. Always use caution when operating it, and do not get your body close to the arc.
  • It will get hot when operating a plasma cutter, so you will want to ensure you have someplace to cool down if you get overheated.
  • Always make sure the plasma cutter is turned off when you are finished using it and any metal is removed from beneath the torch. The pilot arc will take time to cool down and may warp or bend the metal if it’s left unattended.

FAQs

Q: What do I need for a plasma cutter to function?

A: You will need a reliable and functional air compressor and air hose to ensure the plasma cutter works properly. Many may not come with a plug for the air hose, so you will need to check with the manufacturer before buying a plasma cutter.

Q: How hot can a plasma cutter get?

A: Since it is made for cutting thick steel and metals, the pilot arc will reach extremely dangerous temperatures. Use caution when handling a plasma cutter as they can reach temperatures of up to 45,000 degrees Fahrenheit.

Q: How long will it take to cut a piece of metal?

A: It depends on what you are cutting and how you want to cut it. If you just need to slice one piece it shouldn’t take more than a few seconds. If you are making small precise cuts, then it can take a few minutes. Always work slowly and methodically to make sure you stay safe.
