When cleaning, the bevel and surroundings should be ground to a metallic luster.2- For MIG welding, it is recommended to use Ar + 2% O2 as the shielding gas, with a gas flow rate of 20 - 25L/min. For TIG welding, it is recommended to use pure argon as the shielding gas, with a gas flow rate of 8 - 15L/min.3- The above welding methods, conditions and specifications are for reference only. Users should conduct process qualification according to their own welding characteristics before using the wire for formal product welding.
