Max-151AL Low-Frequency Air Plasma Cutter

The Max-151AL is the highest-current model in the non-high-frequency air plasma range. It is engineered for manual cutting and for automated systems alike — CNC cutting tables and robotic cells — and carries digital communication and analogue interfaces as standard for direct connection to automation equipment. Non-HF arc starting removes high-frequency interference completely, so installation next to CNC controls, servo drives and communication equipment needs no special shielding. The high duty cycle supports continuous heavy industrial production, and the three operating modes — standard cutting, continuous pilot-arc cutting and gouging — let one machine handle production cutting, interrupted or expanded-metal work, and weld preparation. Digital soft-switching inverter technology maintains accurate parameters across the whole current range. The controller records consumable cutting time and the number of pierces so that consumable replacement can be scheduled. Automatic gas-pressure detection reduces abnormal torch damage, and automatic over-temperature, under-voltage and phase-loss protection protects the power source. Applications Carbon steel, alloy steel and non-ferrous metals, in industrial power-plant installation, boilers and pressure vessels, shipbuilding, metallurgy, petrochemicals, aerospace, construction machinery and steel-structure fabrication.
