E71T-1C and E71T-1M,Shielding gas designator.2 Indicates the type of shielding gas used for classification. The letter“C” indicates that the electrode is classified using 100% CO2 shielding gas. The letter “M” indicates that the electrode is classified using 75–80% Argon/balance CO2 shielding gas. When no designator appears in this position, it indicates that the electrode being classified is self-shielded and that no external shielding gas was used.
