Frequently Asked Questions
Do I really need an external air compressor for these machines?
Yes, almost every arc plasma cutter requires an external air source to create the plasma stream. While some units have a built-in compressor, these are usually limited to very thin materials. Most professional-grade cutters rely on your shop's compressed air system to function.
What makes a pilot arc torch better than a standard one?
A pilot arc allows the torch to start the cutting process without touching the metal directly. This is extremely helpful when you are working on rusty or painted surfaces that would otherwise block the electrical connection. It also helps preserve your consumables by reducing the initial spark intensity.
Can I use a plasma cutter on aluminum or stainless steel?
Absolutely, as long as the metal is conductive, the plasma cutter will slice through it. Plasma works by ionizing gas, which melts and blows away any electrically conductive material. Just remember that different metals may require slight adjustments to your travel speed and air pressure.
How much amperage do I actually need for home projects?
For most hobbyist work, a unit providing 30 to 40 amps is plenty. This range covers steel up to about half an inch thick quite easily. If you intend to work on thicker structural steel, you should look toward machines that offer 60 amps or more.
What safety gear is essential when I am cutting?
You must wear an auto-darkening welding helmet with the appropriate shade level to protect your eyes from intense UV light. Thick, flame-resistant gloves and a leather apron are also necessary to block the hot sparks and molten metal spray. Never operate these machines in an area with flammable vapors or dust.
