What kind of fuel do plasma engines use?
Compressed air, nitrogen, argon, hydrogen and oxygen, or blends of two or three of these components are the most popular plasma gases for plasma cutting. Most hand-held air plasma systems operate best around 70–80 PSI (4. The exact value depends on the model, torch style, and material thickness. Always refer to your specific manual. For Thermal Dynamics Cutmaster systems, published True Cut™ ratings assume the correct pressure and flow at the torch.When selecting an air compressor for your plasma cutter, consider the tank size based on your cutting needs. For light to moderate jobs, a 20 to 30-gallon tank suffices, ideal for DIY or hobby cutting. For industrial cutting, opt for a 60-gallon compressor for continuous operation and high efficiency.
