The Taurus FCW E71T-1-1.2MM -H4 is a high-quality, highdeposition rutile flux-cored wire with an enhanced degree of fill for Argon/CO₂ gas mixtures. It is ideal for welding 355- 460Mpa steels and thick steel components. The diffusible hydrogen level is consistently below 4ml/100g in deposited weld metal and since the seam of the wire is laser welded, there is no moisture pick-up. The wire is not copper coated and therefore there can be no contamination of feed liners, torches or contact tips resulting from copper flakes. It is designed for welding medium-strength steels (420MPa,61psi yield strength) using either 100% CO₂ shielding or Argon/CO₂ shielding gas mixture (15 – 25% CO₂ and balance Argon).
TYPICAL APPLICATIONS
Hard-facing of hot cut-offs, shear blades, dies for pressure casting, scraper blades, conveyors, rollers, crusher rolls and worn parts in agricultural equipment.
FEATURES
• All positional welding capabilities with outstanding performance in vertical-up welding of fillet and butt welds.
• Coefficient of flux fill and current capacity designed to deliver all positional weldability.
• Savings in welding cost resulting from easy slag removal and lack of spatters. Ideal for applications in shipbuilding and steel construction.
• Designed for mixed gas and the use of 100% CO₂ is possible
WELDING POSITIONS
• Down hand • Horizontal flat • Horizontal vertical • Vertical up • Vertical down • Overhead
