: Many portable units are dual-voltage , allowing them to switch between standard 120V household outlets and 240V industrial supplies.
: Pilot arc technology is highly recommended because it starts without touching the metal, making it ideal for cutting through rust, paint, or expanded metal. Top Product Recommendations for 2026 buy plasma cutter
: This measures how long a machine can cut continuously in a 10-minute window. A 60% duty cycle means six minutes of cutting followed by four minutes of cooling. : Many portable units are dual-voltage , allowing
Buying a plasma cutter requires matching the machine’s power to your most frequent projects rather than just the thickest piece of metal you might ever cut. A high-quality unit should offer efficient cutting speeds, a manageable duty cycle, and affordable, long-lasting consumables. Key Specifications to Consider A 60% duty cycle means six minutes of
: Higher amperage allows for thicker and faster cuts. For light work (up to 12mm), 30A is often sufficient; for professional workshop tasks (up to 25mm), a 40-50A machine is the standard.
These models are frequently recommended by experts and users for their reliability and performance:
: Machines provide three ratings: Recommended Cut (clean, productive speed), Pierce Capacity (can start in the middle of a plate), and Severance (absolute maximum thickness the machine can separate at very slow speeds).
