Send Message Request a Quote

The E70T-4 self shielded mild steel flux cored wire adopts DCEP (Direct Current Electrode Positive). This steel welding equipment generates globular transfer, and delivers fast deposition rate and extremely low sulfur content in both single pass and multi-pass welding.

Additionally, this self shielded mild steel flux cored wire is highly recommended for welding of steel at various levels with no requirements on impact toughness. This self shielded welding wire is also suitable for field maintenance where low precision groove weld joints are satisfying.
