The dairy bends are 1.5mm thick and I've been using 1/16 tungsten.

You are correct for spotting that the pieces I used for welding practice look thicker (it's coming back to me now).

The plan is to build the exhaust with 1.6mm thk pipe. I was lucky to score some free off-cuts of S/S pipe.....except I hadnt initially realised that there was a mixture of 1.6mm thk and 2mm thk pipes!

According to my notes, I did my last weld using 50Amps.
15CFH flow through the torch & 7.5lt/min flow for purging.
The tungsten protrusion was set at 6mm.
...and I was using a no. 9 gas lens! (or is that a no. 6 )
