Category BASICS & FUNDAMENTALS

New to plasma? This section covers the fundamentals—what a plasma cutter is, how the arc forms from compressed gas, and how a torch works (electrode, nozzle, swirl ring). We explain the full plasma cutting process, pilot-arc vs contact-start ignition, basic power and air requirements, and where plasma arc welding fits. You’ll also learn the key advantages and limitations of plasma cutting—speed, kerf width, heat-affected zone, duty cycle, and costs—so you can choose the right setup with confidence. Use these guides to master terminology, compare technologies, and follow essential safety practices before making your first cut.
