CHARACTERISTICS
• Low fumes and low spatter
• Easy slag removal
• Very good out-of-position capabilities

ProStar FC-71LF wire is a flux-cored wire designed
for general purpose fabrication, welding in all positions.
It can be used with either 100% CO 2 or 75% Ar/25% FILLER METALS
CO 2 shielding gas, offering a spray-type transfer of weld
metal. ProStar FC-71LF wire provides good impact
strength at low temperatures. It also has low fume and
spatter levels and the slag is easy to remove.
