Lincoln Precision TIG 275 TIG Welder 208/230/460/1/60 - K2619-1

Lincoln Precision TIG 375 TIG Welder 230/460/575/1/60 - K2622-2

The Lincoln Precision TIG 375 - K2622-2 is a professional-grade TIG welding system engineered specifically for demanding applications requiring superior arc performance and precise control. This versatile power source offers exceptional duty cycle ratings—the highest in its class—making it the ideal solution for fabrication environments tackling thicker materials and extended welding sessions. Featuring multi-voltage input capability (230/460/575V, single-phase, 60Hz), this advanced system adapts to various facility power configurations while maintaining consistent output performance. The integrated TIG pulser technology provides enhanced heat input control, effectively reducing distortion and burn-through on thin materials while allowing for more consistent bead appearance and controlled filler metal deposition.

The Precision TIG 375 incorporates Lincoln's patented Micro-Start™ II Technology, a sophisticated arc management system that significantly enhances starting characteristics and maintains exceptional arc stability throughout the welding process. This advanced technology enables operators to produce more precise welds and achieve superior crater fills, elevating overall weld quality and appearance. The innovative AC Auto Balance feature automatically determines the optimal mix of cleaning action and penetration when welding aluminum materials, simplifying the welding process while ensuring excellent results. For applications requiring specific performance characteristics, the system allows operators to manually adjust the AC Balance to increase or decrease cleaning action or penetration on aluminum based on specific project requirements.

Designed for maximum operational flexibility, the Precision TIG 375 delivers an impressively wide output range from 2 to 420 amps—the broadest in its class—enabling operators to tackle materials across the entire thickness spectrum with a single machine. The standard Advanced Pulse Control panel provides comprehensive pulse parameter adjustment capabilities, allowing precise tailoring of the welding output to specific application requirements. Thoughtful design elements include side-mounted torch holder and connections that facilitate cable management and provide convenient torch storage when not in use, enhancing workplace organization and protecting valuable components. This comprehensive combination of advanced technology, precise control capabilities, and practical design features establishes the Precision TIG 375 as an exceptional solution for professional welding operations requiring maximum performance and versatility.
