Despite its small size, the Powermax30® AIR delivers big performance. This small air plasma cutter — the smallest, lightest handheld plasma cutter in its class — includes its own built-in air compressor. That’s right, it’s a small plasma cutter with a built-in compressor so you can use the Powermax30 AIR anywhere there’s single-phase power. ust plug it in, attach the work clamp and you’re ready to cut.
