First of all a quick hello, as this is my first post on the Miller site

I am based in the U.K. and am a keen motorcyclist, and amateur fabricator of all things conected therewith.

My current project is a 1989 Harris F1, here's a photo of the 'bike when I first got hold of it:

I am rebuilding it from the ground-up, and have bought myself a Dynasty 200DX so that I can learn to weld, & fabricate some parts that I need. The next stage in the project is to build a seat sub-frame from 10mm (just less than half-inch) square tube.

I would appreciate suggestions for some settings on the machine, to TIG weld 1.5mm (1/16th inch?) thick aluminium. I have some experience with MIG and gas welding, and have played around a bit with TIG and am making steady progress.

Your help much appreciated,
