Characteristics | (1) CSF-71SRM is a titania type flux cored wire and designed for all-position welding by single pass & multi pass with 75%Ar + 25%CO2 gas shielding. (2) It provides the excellent usability with stable arc, less spattering, good bead appearance, better slag removal, and less quantity of welding fume comparable to solid wire. (3) It provides excellent impact value at low temperatures in the as-welded and PWHT conditions. |
Notes on usage | (1) The optimum flow of 80%Ar-20%CO2 for shielding is 20~25ℓ/min. (2) The distance between tip & base metal is to be 20~25mm. (3) Protect the weld with a screen to prevent blowholes caused by wind where the wind velocity is 2m/sec and more. |
Shielding Gas | 80~75%Ar-20~25%CO2 |
