Which Plasma Cutter Handles Your Metal Best?

Plasma cutters are rated by recommended and severance thickness — but real-world performance depends on duty cycle and clean, dry air just as much as raw amperage.

For thin sheet and bodywork, a 30–45 amp machine delivers clean, dross-free cuts. For half-inch plate and structural steel, look at 60 amps and up with a generous duty cycle so you can keep cutting without thermal shutdowns.

Whatever you choose, invest in a quality air dryer. Moisture is the number-one cause of poor cut quality and short consumable life.
