This tubular wire combines excellent operator appeal with mechanical properties superior to most conventional E71T-1 wires. A soft quiet arc with virtually no spatter produces a weld deposit with diffusible hydrogen levels typically less than 5ml/100 g required by MIL-E-24403/1.

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.
• See Above: This information was determined by welding with 100% CO2 shielding gas with a flow rate between
35-50 cfh (14-24 l/min).
• All positions include: Flat, Horizontal, Vertical Up, and Overhead.
