Recommend setting for 5mm 316 fillet

[MattH]

I need to weld a threaded boss into a short piece of 3" 316 pipe.
I am set up with a No7 cup, a gas lens, 1.6mm Gold Tungsten and 1mm 316 filler.

The two pieces are both 5mm wall.

Can you kind chaps recommend some starting amps and what about my set up?

The last time I turned the TIG set on was 2 years ago and that was all Ali.

I'd say a 2.4 and 140-160a

Yep, spot on. I am impatient and went for it but had to go up to a 2.4 filler. Blasted it in at 170A.

Not pretty but it will do the job well enough which was to T in a vacuum relief valve to one of my big side channel blowers without spend £100 on plumbing parts.

One of @Richard. super sharp tungstens:

It’s done and it’s certainly not going anywhere
I’d of been a good chunk lower than that myself
They look very hot
For me 120-130 1.6-2.0 filler.

Yep me too I would of said 125A. You can usually knock a good 20% off the temperature you'd weld mild steel of that thickness at for stainless.

I started at 120A but it seemed to take an age to pool up properly and I thought I’d be putting just as much heat in hanging around.
Granted at 170A it was way to hot but I just blasted around and got it done.
