K3946-2 - Lincoln Aspect 375 AC/DC Water-Cooled TIG Package

Advanced Industrial AC/DC TIG Welding Solution

The Lincoln Electric Aspect® 375 AC/DC TIG Welder Ready-Pak® (K3946-2) represents the pinnacle of mission-critical welding technology. Designed for the most demanding industries—including aerospace, motorsports, shipbuilding, and heavy fabrication—this machine delivers precise arc control and superior weld quality. The unit is engineered with PowerConnect® Technology, allowing it to automatically accept any input power from 200V to 600V, single or three-phase, 50 or 60 Hz, without manual linking. This flexibility ensures the Aspect 375 can be deployed in virtually any facility worldwide.

At the core of the Aspect 375 is its advanced inverter technology, which provides extremely fast arc response and stability. For aluminum applications, the machine features AC Auto Balance® technology, which simplifies parameter setup by automatically calculating the optimal mix of cleaning and penetration. For more experienced operators, the AC Wave Shape control offers deep customization, allowing users to adjust offset, frequency, and wave balance to modify the arc profile for specific joint configurations. This level of control is essential for breaking through heavy oxide layers or maintaining a narrow arc in tight corners.

The Ready-Pak configuration is a comprehensive turnkey solution that includes the CoolArc® 47 Water Cooling System, a heavy-duty inverter cart, and a premium water-cooled TIG torch. The system boasts a robust duty cycle of 40% at 330 amps (3-phase), making it suitable for continuous production environments. Additionally, Intellistart™ technology optimizes arc starting characteristics, providing softer starts for thin materials to minimize distortion and hotter starts for thick materials to ensure immediate fusion. With memory storage for up to 9 procedures, operators can quickly recall settings for recurring jobs, enhancing consistency and productivity.
