OVERVIEW

Precision Automated Plasma Power Source

The ESAB Thermal Dynamics Cutmaster A40 is a premium automated plasma cutting power source designed to deliver reliable performance for light to medium-duty CNC applications. Engineered with the needs of modern fabrication in mind, the A40 combines a high duty cycle with a compact, lightweight inverter platform. This unit is specifically configured for automated tables, offering a seamless interface with CNC controllers for Start/Stop, OK to Move, and Divided Arc Voltage signals.

With a 40 Amp output, the Cutmaster A40 is capable of piercing up to 3/8 inch (10mm) mild steel and edge cutting up to 5/8 inch (15mm). Its 80% duty cycle at maximum output ensures that production runs can continue with minimal interruption, making it an excellent choice for HVAC ductwork, sign manufacturing, and general sheet metal fabrication. The unit features intelligent Auto-Voltage detection, allowing it to accept single-phase input power ranging from 208V to 480V without manual linking or rewiring.

The A40 is designed to work with the legendary SL100SV 1Torch (sold separately or in kits), which utilizes Thermal Dynamics' proprietary SureLok electrode technology for consistent arc starting and extended consumable life. The system's electronic pilot arc controller improves reliability and reduces high-frequency interference, protecting sensitive CNC electronics. Whether you are retrofitting an existing table or building a new automated system, the ESAB A40 provides the stability and precision required for high-quality cuts.

Key Technical Benefits

  • Automation Ready: Comes standard with a CNC interface port for easy integration into gantry or table systems.
  • Global Input Power: Automatically adjusts to any single-phase voltage between 208V and 480V.
  • Superior Torch Technology: Optimized for the SL100SV torch, offering excellent cut quality on steel, stainless, and aluminum.
  • Rugged Durability: Built to withstand industrial environments while maintaining a small footprint.

FAQ

The ESAB A40 has a recommended pierce capacity of 3/8 inch (10mm) and a maximum edge cut capacity of 5/8 inch (15mm) on mild steel.

This specific SKU is typically for the Power Source (PS) only. It is designed to be paired with the SL100SV 1Torch, which may need to be purchased separately or as part of a different kit.

The A40 accepts Single Phase input power from 208V to 480V. It features Auto-Voltage detection, so no manual linking is required.

Yes, the Cutmaster A-Series is specifically designed for automation. It includes a standard CNC interface for Start/Stop, OK to Move, and Divided Arc Voltage signals.

The machine is rated at 80% duty cycle at its maximum output of 40 Amps, allowing for extended cutting sessions without overheating.

While designed for automation, the power source can operate a hand torch if equipped with the appropriate adapter and torch, but its primary configuration is for machine cutting.

It requires clean, dry, oil-free compressed air or nitrogen. The recommended pressure and flow rate should match the specifications of the attached torch (typically around 70-75 PSI).

ESAB typically offers a 3-year warranty on the power source and a 1-year warranty on the torch (if included), though terms should be verified at the time of purchase.
