ER70S-2 is a premium MIG & TIG wire for
welding on all grades of mild and carbon
steels, producing quality welds with minimal
porosity. It is a triple deoxidized wire
(Zirconium, Titanium, and Aluminum)
making it an excellent choice for welding
over rust and mill scale. No flux is required
with this product. This wire is available
spooled or in cut-length form.
Typical Applications
• Pipes and offshore drilling rigs
• Structural steel work
