Hi all,
I'm having a bit of trouble with root pass suck back using .045 DW-309LP (Kobe) FCAW filler to weld 2G and 4G open groove on dissimilar metals (HSLA, high CE). Using similar parameters in the 2F and 4F I'm getting great results, as well as intermediate and cover passes on the grooves.
I'm running an Invision 456MP MIG mode @60% inductance
28.5v
350ipm
100% CO2
Is there anyone with any tips on how to eliminate the suck back? I'd normally just toubleshoot for a few hours but the material I'm using is limited in supply and quite expensive, so I need a fast track.
Thanks in advance,
FF
