ProStar Steel & Bronze TIG Rod

ProStar Steel
ER70S-2 is used primarily for single-pass TIG welding
of steel, but may also be used for some multi-pass TIG Welding Rods
applications. Because of added deoxidants, ER70S-2
can be used for welding steels that have a rusty or Recommended shielding
dirty surface, with a possible sacrifice of weld quality, gases: argon or helium/
depending on the condition of the surface. argon mixture

ER70S-6 contains higher levels of manganese and silicon
than ER70S-2, and it produces high-quality welds when
used on dirty, oily or rusty steel. The high silicon content
increases the fluidity of the weld pool, resulting in smoother
bead appearance and minimal post-weld grinding.
