309L in the 5F position

GMAW-Pulse, with a helium mix gas would be a good start

Haven’t welded any S/S pipe that thin with 309 wire, however welding S/S plate to C/S plate we used 309L wire in a Fronius TPS 2700 machine. Gas used if I remember correctly was Argoshield Heavy.

I found that the Austalian Edition TPS2700 machine was far better than the normal TPS2700.  This is due to the Aust model having a specific setting for 309 wire. More noticeable in out of position welding. Can’t remember if pulse was used – don’t think it was – but for 0.9mm pipe, I would recommend it.

Gary.

was it Stainshield heavy or Argoshield Heavy the later would have too much CO2 I would have thought

This was going back about 4 years ago now. I’m pretty sure it was Argoshield heavy.  I remember the bottle being the same color as the argoshield universal, just with darker band on the top.

Stainshield also has the black band on top, which I can’t recall seeing.

Having said that though, I have used Argoshield universal for 309 wire. This was just general maintenance welding though.

Gary
