0559356344 - ESAB A-Series A40i Automated Plasma Cutter Power Source

Precision Automated Air Plasma System

The ESAB A40i (0559356344) represents the entry point into the high-performance A-Series of automated air plasma systems. Engineered specifically for mechanized applications, the A40i combines advanced inverter technology with a user-friendly interface to deliver superior cutting results on mild steel, stainless steel, and aluminum. With a 400V 3-phase input, this unit provides a stable and powerful arc capable of piercing and cutting with high precision, making it an ideal power source for entry-level to mid-range CNC tables.

Superior Duty Cycle and Performance
One of the standout features of the A40i is its impressive 80% duty cycle at the maximum 40 Amp output. This allows for continuous production cutting on materials up to 12mm thick (production pierce) without the frequent cooling pauses required by lesser machines. The system utilizes the renowned SL60 SV 1Torch, which features a valve-in-torch design. This architecture significantly improves cycle times by metering gas flow closer to the arc and enhances consumable life by ensuring proper cooling and arc initiation.

Seamless Automation Integration
Integrating the A40i into your existing CNC setup is straightforward thanks to the included CNC interface. The rear panel provides access to Start/Stop inputs and OK-to-Move (Arc Transfer) outputs, allowing for immediate communication with your table's controller. The internal voltage divider card (optional or included depending on specific package configuration) can provide scaled voltage for torch height control (THC) systems, ensuring consistent standoff height and cut quality across warped or uneven plates.

Advanced 1Torch Technology
The A40i is optimized for use with the Thermal Dynamics / ESAB 1Torch consumables. These consumables are designed for precision, offering a constricted arc that produces narrow kerf widths and minimal heat-affected zones (HAZ). The Start Cartridge technology eliminates high-frequency interference, protecting sensitive CNC electronics from electrical noise. Whether you are upgrading an older table or outfitting a new installation, the ESAB A40i delivers the reliability and cut quality professional fabricators demand.
