WebUna longitud (CTWD) demasiada larga puede provocar una caída de amperaje, falta de penetración y / o pérdida de gas protector. Cuando la longitud (CTWD) es demasiado corta, se pueden presentar porosidad o huellas de gusano cuando se usan alambres con núcleo fundente (FCAW). La longitud (CTWD) varía según el metal de aporte que se utilice. WebUltraCore® 70C. Flux-Cored Gas-Shielded (FCAW-G) CLASSIFICATIONS: E70T-9C-H8. E70T1-C1A2-CS1-H8.
