Designed as a low Manganese (Mn) E71T-1M product to assist with conformance to OSHA requirements and NIOSH and ACGIH recommendations for Manganese. This product offers reductions of Mn in the weld fume of 60-80% over a standard E71T-1M product with low diffusible hydrogen as well as enhanced operator appeal and excellent out of positional capability.

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: The information above was determined by welding using 75% Ar/25% CO2 shielding gas with a flow rate between 35- -50 cfh (14-24 l/min).

All positions include: Flat, Horizontal, Vertical Up, and Overhead.
