1. Welding workpiece should be done oil removal, rust removal treatment.
2. During welding , the gas flow is generally between 20 and 25 L / min .
3. When flux-cored wire is welded, the dry elongation should be 15 ~ 25 mm.
4. Welding wire warehouse humidity should be maintained no more than 60%.
5. Non-vacuum packaging wire storage time should not exceed half a year, vacuum packaging wire storage time should not exceed one year.
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.
