  • 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.
