0559356341 - Thermal Dynamics Cutmaster A40 Automated Plasma Power Source

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.
