Description:

SFC-71 is an all-position rutile flux cored wire designed to be used with CO2 or Ar/CO2 gas mixture. It can be used on all-position welds with both single and multiple pass weld position  stablen mild steel and low alloy steels.

Applications :

It is widely used for shipbuilding, storage vessels, structural fabrication,machinery and piping, etc.

Note On Usage :

1. Use DC (+) polarity.

2. Maintain a higher welding speed in order to get enough penetration in down hand welding position.
