Managed to get hold of a big box of offcuts of 3 inch stainless tube for not a lot of money to use as practice pieces as I'll be doing an exhaust for my old Escort in the near future. Anyway, it's 1.5mm wall and a closed butt joint. Now according to the cheat sheets on here that needs 40amps to weld. At 40 it didn't get any penetration and some of the bead looked a bit cold.
So for the second half I run 45 amps after letting the part cool for about fifteen twenty minutes. This seemed a bit hot to me but I did get a bit of penetration in places. I'm moving at a fairly quick pace to avoid putting too much heat in but don't feel I'm getting ahead of the puddle. Any tips from you guys would be great.
Just to add, first pic is 40 amps, second is 45 amps. first purge is 40 amps and the other two show the areas welded at 45 amps.
