  • They Are The Most Commonly Used Electrodes Today And Are Preferred For Their Longevity And Ease Of Use
  • This Electrode Operates Far Below Its Melting Temperature,Which Results In A Considerably Lower Rate Of Consumption And Eliminates Arc Wandering For Greater Stability
  • Unlike Pure Tungsten,These Electrodes Are Only For Specialty Type Ac Welding (Thin Gauge Aluminum Or Materials Less Than .060-In.),But They Are Exceptional For Dc Electrode Negative Or Straight Polarity On Carbon And Stainless Steel,Nickel And Titanium Applications
