The new AirForce™ 12ci Plasma Cutter with Built-In Air Compressor features an inverter design that is both lightweight and powerful. The new XT series torch and longer life XT tips and electrodes provide added performance to an already exceptional plasma cutter. The unit features a built-in compressor for total portability and low system cost. Cuts mild steel up to 1/4in. thick using standard household current. The new XT12R torch is more comfortable, efficient and economical. Plasma cutters cut faster and more precisely with a thinner kerf and less slag than cutting with oxy fuel. A smaller heat-affected zone also causes less warping. And you'll never have gas pressure settings, flame tuning, metal preheating, or gas cylinders or refills to worry about.
