The enhaced filling degree of FCW 140 results in higher current carrying capacity and deposition rate. Thus, welding speed is essentially increased which leads to a saving of time and costs. FCW 140 is also well-suited for fully mechanized welding by means of vertical-welding unit. The weld metal produced features excellent mechanical-technological properties and a guaranteed hydrogen content of < 5 ml per 100 grams of weld metal. Low spatter loss, easy slag removal, finely rippled, pore-free welds without undercutting into the base metal. FCW 140 is preferably used with mixed shielding gas.

FCW 150 W is a rutil flux cored wire especially developed for Cortenand Patinax kind of weathering steels. The weld metal is resistant to atmospheric corrosion. Used under CO2 gas shield. Stable welding performance in short, spray and pulsed arc applications alike.

FCW 181 is a metal cored wire designed for fine grain steels requiring maximum 800 N/mm2 yield strength. High creep rupture strength until 600°C. Low spatter loss, high deposition rate and slagless fine rippled beads which are free from porosity.
