K2535-1 - Lincoln Precision TIG 225 AC/DC Welder Ready-Pak

Unmatched Precision and Versatility in TIG Welding

The Lincoln Electric Precision TIG 225 Ready-Pak (K2535-1) is engineered to deliver professional-grade performance for a wide variety of industrial and fabrication applications. Designed with the serious welder in mind, this machine boasts the widest operating range in its class, delivering anywhere from 5 to 230 amps. This broad amperage capability allows operators to tackle everything from thin automotive sheet metal to heavier structural fabrication with a single machine. At the heart of its performance is Lincoln's patented Micro-Start II Technology, which ensures extremely stable low-amperage starting, welding, and cratering for both AC and DC processes. This technology is critical for achieving precise, high-quality welds on delicate materials where arc stability is paramount.

For aluminum welding applications, the Precision TIG 225 features AC Auto-Balance. This intelligent system automatically adjusts the ratio of cleaning action versus penetration, ensuring optimal weld quality without the need for complex manual tuning. However, for experienced operators requiring specific arc characteristics, the system allows for manual override to prioritize cleaning for heavy oxide layers or penetration for thicker sections. Additionally, the integrated TIG Pulser is a vital feature for controlling heat input, significantly reducing material distortion on thin substrates and helping to moderate filler metal deposition for a consistent, aesthetically pleasing bead appearance.

Beyond its TIG capabilities, this machine is an excellent Stick welder, capable of running up to 5/32-inch (4.0 mm) electrodes, including the demanding Fleetweld 5P (E6010). The unit is built for the shop environment, featuring Fan-As-Needed (F.A.N.) technology that minimizes noise, power consumption, and the intake of dust and debris by running the cooling fan only when necessary. The Ready-Pak configuration ensures you have the essential components to start welding immediately, including a PTA-17 air-cooled torch with Ultra-Flex cable, a heavy-duty foot pedal (Amptrol), gas regulator, and work cables. With its robust construction and advanced wave control features, the Precision TIG 225 is a reliable workhorse for maintenance, repair, and production environments.
