We have always used 309L when welding 304 Stainless but was recently told that 309LSI might be better and it would leave better looking welds with less clean up. Our shop uses mostly tig welding but recently invested in a new Miller Mig welder and it is a learning curve. Our equipment is mostly miller but getting older. Any help would be appreciated.
Also we have never used flux core wire either, any ideas?
Thanks,
