ProStar ER70S-3 Wire – 0.035 in – 33 lb

ProStar ER70S-3 wire is typically used on clean, oil-free and rust-free base material. With a reduced silicon content, it helps avoid silicon islands that can form on top of the weld, giving it a glassy look. Paint applied over a silicon island may later flake off. In addition, with multiple pass welding, a silicon island may be detected on an x-ray as a slag inclusion. Such defects may require costly rework.
