LFC-711 Characteristics and Applications:

LFC-711 is an all-position flux cored wire designed to be used with CO 2 or Ar/ CO2 gas mixture. LFC-711 can be used on all-position welds with both single and multiple pass welds on mild and low alloy steels. Typical applications include shipbuilding, storage vessels, structural fabrication, machinery and piping etc.

Notes on Usage: 1.Use DC(+) polarity. 2. In order to get enough penetration in the downhand weld position, maintain a little bit higher welding speed by stringer manipulation for the first pass.
