Plasma cutters need air pressure to cut in a two-stage process. First, the arc heats the metal until it's semi-gaseous. Second, the plasma is forced by blasts of air to finish the cut. Therefore, all plasma cutters need an air compressor to generate enough air pressure for the task.
Yet, how big of an air compressor do I need to run a plasma cutter?
Ideally, you'll want to buy a compressor whose CFM rating is higher than your plasma cutter or one that is rated about 1.5 to 2 times the CFM of your cutter to ensure that your machine doesn't stop temporarily when the air compressor takes time to refill.

Can I weld with a plasma cutter?
With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.
HZXVOGEN 40 Amp Plasma Cutter with Built-In Air Compressor 220V Digital Inverter IGBT Clean Cut Cutting Machine (Model: HBC6000Pro)
- READY TO CUT PLASMA CUTTER - HZXVOGEN HBC6000Pro plasma cutter equipped with built-in air compressor, do not need to install air compressor regulator. You literally just need your plasma cutter and a power source to start cutting. This makes doing jobs out in the field incredibly easy
- PERFECT CLEAN FINISH, SAVE TIME AND MATERIAL - Severance cut thickness* ≤ 1/2"(12mm), ideal cut thickness ≤ 2/5"(10mm). It is hard to find a plasma cutter have gas delay function, but our HBC6000Pro plasma cutter does. With this function, it will bring even cuts, little deformation and little slag. Do not need to grind too much after cutting
- TWO EXTERNAL AIR FILTERS, LONGER SERVICES TIIME - The two air filters of HBC6000Pro plasma cutter are to make the compressor air clean, keep dust outside the machine, and reduce noise. Most of the plasma cutter equipped air filter inside the machine, but ours are external, which protect electronic components being damaged by high temperature
- AIR SWITCH PROVIDES COMPREHENSIVE PROETCTION - Most of plasma cutters are equipped with rocker switch which can withstand lower current and does not have leakage protection. Our plasma cutter came with high-power air switch which can withstand higher current and power off automatically when short-circuit or leakage to protect you, machine and your power system

Compressed Air is the most commonly used gas for lower current plasma cutting and works well for most metals from gauge thickness to 1 inch. ... Compressed air can also be used for plasma gouging on carbon steel. Nitrogen is often used for higher current plasma systems and for cutting materials up to 3 inches thick.
It's important to know if the compressor you purchase will drive the air tool you'll need for your project. For example, smaller air nailers run on 2 to 5 CFM at 70 to 90 PSI, while larger shears, air sanders require up to 10 or more CFM and 100 to 120 PSI.
Of all the plasma cutters in the industry, only the Spectrum 375 CutMate™, Spectrum 2050 and Spectrum 3080 plasma cutters consistently cut steel at or greater than 3/8 in. when using generator power. ... When connected to a generator with at least 8 kW of power, such as the Bobcat 225 NT, it cuts steel up to 5/8 in.
There's no soot, very little mill scale,” he says. “You can cut pipe through the coating with no problem whatsoever, and it doesn't disturb the coating or mechanical properties of the pipe.” ... Plasma arc cutting offers an efficient and cost-effective alternative to oxy-acetylene cutting and carbon arc gouging.
