This wire has a basic slag system and is designed for use where deposit quality and properties are of a first concern. Weld metal hydrogens are very low making this wire more crack resistant than the acid slag types of wires.

• 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). For 80% Ar/20% CO2 shielding gas, reduce voltage by 1-2 volts.
