LT·E711 1.2/1.4/1.6mm CO2 Gas Shielded Flux Cored Arc Welding Wire
E71T-1C was developed for welding mild steel and 490MPa high tensile strength steel and launched into the world of arc welding nearly 30 years ago.
The prefix of the trade designation, DW, was coined from the words, Dual Wire, because the wire consists of steel sheath and cored flux. This development provided the momentum for shipbuilders and bridge constructors in particular to employ semiautomatic and automatic welding with
E71T-1C instead of shielded metal arc welding with covered electrodes. This is why E71T-1C is called an epoch-making flux-cored wire.
