3-2772 - Thermal Arc Ultima 150 Precision Plasma Welder

Precision Plasma Welding Power Source

The Thermal Arc Ultima 150 (SKU: 3-2772) is a state-of-the-art inverter-based Plasma Arc Welding (PAW) power source designed to meet the rigorous demands of high-precision industries. Engineered for versatility and control, this unit provides a wide current output range from as low as 0.5 Amps up to 150 Amps, making it an exceptional choice for applications ranging from micro-component assembly to general fabrication. The Ultima 150 utilizes advanced inverter technology, which not only reduces the physical footprint and weight of the machine but also ensures a smooth, stable DC output that is critical for consistent weld quality.

One of the defining characteristics of the Ultima 150 is its ability to maintain a stable arc at extremely low amperages. This capability is essential for welding thin foils, medical instruments, and electronic components where heat input must be strictly controlled to prevent burn-through or metallurgical damage. The machine features a built-in Pilot Arc circuit, which facilitates reliable arc starting without the need for high-frequency initiation that could interfere with sensitive surrounding electronics. This makes the Ultima 150 particularly suitable for automated environments and clean-room applications.

The unit is equipped with digital metering for precise setting and monitoring of welding parameters. Operators can preset amperage levels to ensure repeatability across production runs. The control panel is designed for intuitive operation, allowing for easy adjustment of plasma gas flow and shielding gas flow. As a dedicated plasma welding system, it offers the benefits of a constricted arc—higher energy density, greater directional control, and a narrower heat-affected zone compared to traditional Gas Tungsten Arc Welding (GTAW). The 3-2772 model is the EMC (Electromagnetic Compatibility) version, ensuring compliance with strict industrial standards for electrical interference.

Integration with automated systems is straightforward, thanks to the machine's remote control capabilities. Whether used in a manual benchtop setup or integrated into a robotic cell, the Thermal Arc Ultima 150 delivers the reliability and performance required for critical welding tasks in the aerospace, medical, and defense sectors.
