Lastifil 20TM is a metal cored copper coated seamless wire. It has excellent welder appeal and superior arc stability. It produces spatter free welds, eliminating the need for costly cleaning.
Slag free weld beads allow for multi-pass welding without deslagging or worry of slag entrapment.
Lastifil 20TM combines the high deposition rate of flux cored wires with the low slag volume and the efficiency of solid wires. (Deposition rate 7 to 10 kg/hr.)
The high current density characteristics allow for faster travel speeds than obtained with solid wires. Due to better root penetration a smaller joint angle can be used.
Boiler work, general plate and sheet metal fabrication, off shore constructions, all mild and medium tensile steels.
Structural steel: S185, S235 - S355 (EN 10025).
Boiler plate: P235GH, P265GH, P295GH (EN 10028-2).
Pipe steel: P235T1 - P355N (EN 10217-1); P235T2 - P355N (EN 10217-3); StE290.7TM - StE480.7TM (EN 10208-2).
API steel: X42 - X70.
Fine grain steel: StE355 - StE460 (EN 10028-3).

The coppered seamless wire can be welded with standard driving wheels but for smaller types of driving wheels the serrated wheels for tubular wire can work better.
