ProStar Flux-Cored Wire

ProStar Premium Quality Flux-Cored Wire

Flux-cored arc welding offers many advantages over solid wire and
covered electrodes. Higher deposition rates, better penetration, improved
sidewall fusion, and an enhanced ability to weld over mill scale or
rust, with less operator skill, are important advantages of this wire.

ProStar Gas-Shielded Flux-Cored Wire

ProStar tubular flux-cored wire is used in applications where the base metal
thickness is greater than 1/4" (6.3 mm) and where the parts to be welded
have poor fit-up or contain some amount of dirt, oil, rust or mill scale.

ProStar Self-Shielded Flux-Cored Wire

Designed for work environments subject to crosswinds (i.e. outdoor
construction), or for areas where it is difficult to provide cylinders of shielding
gas. ProStar self-shielded cored wire is formulated to produce its own
shielding environment as a result of the decomposition of components
present in the core of the wire and neutralization of the nitrogen gas.
