PH: +1.216-481-8100 • www.lincolnelectric.com OUTPUT INPUT 1 PHASE L WHAT’S INCLUDED IN CO LN ELECT RI C Top TIG Welding Performance • Square Wave™ Technology – Delivers a low peak current and fast positive / negative transition time. High frequency arc starting is used for both AC and DC TIG welding modes. You experience reduced tungsten spitting, tungsten electrode erosion and a smooth, stable AC welding arc. • Standard Auto Balance® control automatically delivers optimal mix of cleaning action vs. penetration. • Excellent low amperage starting performance – down to 10 amps. It's Like Getting a Stick Welder for FREE! With outstanding general purpose AC/DC stick welding capability, you can tackle steel, stainless, cast iron and hardfacing applications, including AWS E6010 electrodes like Fleetweld® 5P+. Standard Foot Amptrol™ – Remotely controlling your current level is an added expense with other TIG welders in this class. Enhanced TIG Torch Handling – Includes a rugged Series 17 torch with Ultra-Flex™ cable. The torch is detachable for easy repair or to use optional torches for especially tight spaces or unusual applications. Automatic Remote Sensing – The unit automatically senses when a remote current control, such as the foot or hand Amptrol™, has been connected. Shielding gas pre-flow and post-flow – Built-in 0.50 second pre-flow and 15 second post-flow timers purge and protect the weld and tungsten. Two Year Extended Warranty Available in U.S.A. and Canada.

PERFORMANCE AC Auto Balance® Controls — Automatically sets the optimal cleaning vs. penetration level for aluminum welding! Patented AC Auto Balance® automatically sets the ratio of cleaning action (+) versus penetration (-) based on amperage. WELDING AMPERAGE More Cleaning (+) WELDING AMPERAGE When aluminum welding, the positive (+) portion of the AC welding amperage cleans the oxides from the aluminum surface. The negative (-) portion delivers more heat input, increasing penetration level. Less Cleaning (+) TIME Less Penetration(-) TIME Auto Balance® Results More Penetration (-) RECOMMENDED...
