TIG Welder

Miller Electric Mfg. Co.has incorporated Blue Lightning high frequency, noncontact arc starting technology on all of its 200-, 350- and 700-amp Dynasty AC/DC and Maxstar DC TIG welders. It was previously available only on 200-amp models. Blue Lightning provides consistent, reliable high-frequency arc starting at all amperages, including as low as 1 amp on Maxstar and Dynasty 200 models, 3 amps on Maxstar and Dynasty 350 models, and 5 amps on Maxstar and Dynasty 700 models. Blue Lightning sets the optimal starting parameters based on tungsten size (from 0.020- to 0.250-inch diameter), eliminating operator guesswork. The technology controls four arc starting variables: amperage, time at amperage, slope time and minimum amperage for various tungsten sizes. This increased control ensures the arc start and eliminates the current over-shoots that cause burn-through. Aerospace welding, tool/die welding and other low amperage TIG applications especially benefit. For more information visit www.MillerWelds.com or call (800) 426-4553.
