Advantage: 1. Most common used./ Lower Electronic Function./ Higher Crystallization temperatures./ Better conductivity/ Better Mechanical Cutting Performance. 2. Low melting rate/ Longevity usage/ Good performance for DC 3. Easier arc starting capabilities./ Good arc resistance, not spread around and disperse the arc. 4. Applicability: AC welding: thin-gauge aluminum and material less than 0.060" DC welding: Carbon steel, stainless steel, nickel, and titanium.
