I have been trying to weld together a stainless steel rail and in 3 days I have 20 ft out of 240 foot done. My setup is millermatic 211 Auto set with MVP wire is ER308L size 0.023. In 11 lb spool. Gas is tri-mix. I am having the hardest time keeping the rail straight and at the angle since it is a rake rail. All the welds are coming out really bad and it is going to need some serious finish work. I don't know what grade ss it is but it is sch 40 size and bends. I also have a millermatic 350p that I could use with the spool gun if that would make a better looking weld. I need some help with this one guys, I love welding but not lately. Any tips or xp with ss would help

Pics of the welds would be helpful....
BTW .023 is usually used for thinner stuff... like 12 Ga and smallerLast edited by H80N; 10-28-2014, 03:57 PM..

Here is an old tread on it..

Also...I do hope that you are NOT trying to use the AUTOSET feature on stainless....

Tri Mix... Which Tri Mix...???

if we look at the cross reference and selection manual... the selection is formidable....
