FCW R 690
Description & applications
- Seamless copper coated rutile flux cored wire for gas shielded metal arc welding
- 2.2% nickel alloyed to improve sub-zero impact strength and tensile properties
- Single and multiple pass welding of high strength steels
- High deposition rate welding can be carried out in all positions without the need to change parameters
- No moisture pick up, excellent wire feeding properties, good weldability and low spatter
- Extremely low hydrogen content over the whole parameter box
- For use with mixed gas
