diamondspark NiCu1 BC is a seamless, weather resistant flux-cored wire of the basic type, alloyed with copper and nickel.
It is used on grades such as S235JRW and ASTM A 588. The seamless sheath keeps moisture away from the core even after longer storage, and the wire goes into structural steelwork, on tanks, piping and series production.

Clean rust, paint and grease out of the groove, contaminated plate gives porosity even with well set parameters. Hold a short arc, a long one breaks the shielding and raises the hydrogen content in the weld. Take care of degassing and a clean groove, basic slag will not forgive oily edges. Thinner diameters suit root runs and thin sheet, thicker ones the fill passes.
