OVERVIEW

Precision and Reliability for Your CNC Table

Take your automated cutting to the next level with the ESAB A40i, a plasma power source built to work as hard as you do. If you are running a CNC table and need a reliable, easy-to-use 40 Amp system, the A40i is the perfect upgrade or replacement. Unlike handheld units adapted for tables, this machine is designed from the ground up for automation, giving you cleaner cuts, longer consumable life, and less hassle during setup.

The A40i shines where it counts: uptime. With an 80% duty cycle at full power, you can run longer programs without waiting for the machine to cool down. It pairs perfectly with the SL60 SV 1Torch, which is famous among fabricators for its quick-change consumables and tight, focused arc. This means you get less dross, squarer edges, and parts that are ready for welding right off the table. The "SV" solenoid valve is built right into the torch head (or close to it in the mounting block), ensuring instant gas control for precise starting and stopping.

Installation is straightforward thanks to the included CNC interface cable, which connects easily to most standard table controllers. Whether you are cutting HVAC ductwork, custom brackets, or artistic metalwork, the A40i delivers the consistency you need. It handles expanded metal effortlessly with its auto-pilot restart mode, so you don't have to worry about the arc extinguishing over gaps. Compact, powerful, and backed by ESAB's reputation, the A40i is the smart choice for modern fabrication shops.

Why Fabricators Choose the A40i:

  • High Productivity: Cut longer with less downtime.
  • Superior Cut Quality: 1Torch technology delivers precision edges.
  • Easy Integration: Plug-and-play with most CNC controllers.
  • Versatile: Cuts mild steel, stainless, and aluminum effectively.
