I use a Jackson Halo hood with a NexGen auto-darkening lens. The Halo hood is light and comfortable. Looking through most lenses has a green color to them, the nexgen lens has an amber color that looks better and gives awesome clarity.
These alloys don't really require any kind of special machine. I did all of this work with a TIG machine on DC-, a variable pedal, with the amperage set at 70 and no special pulse settings, just straight current. So any machine that can do that (pretty much any TIG machine in existence) could theoretically make these welds. Of course, some older machines and a lot of newer machines will just generally work better than others and thus make things a bit smoother and easier to do.
What alloys like this and pretty much any material requires for TIG welding is extremely clean work, that is always well gas covered. Abrasive clean all the surfaces to be welded, inside and out, scotch brite pads work good for that. Wipe down the area to be welded and your filler rod with acetone or other cleaner that will remove dirt and oil but evaporates and leaves no residue. With materials like Stainless, Inconel, and Titanium, gas coverage is extremely important. Always use a gas lens on the torch, seriously, if you are not using gas lenses you are really missing out. They also must be back purged, that means there must be gas on the back side of the weld too, if you dont do this, you are majorly fucking up the metal and may as well just make it out of mild steel.
I'm gonna stop there because I can really go on and on about this. Welding and fabrication is my passion, sometimes I cant shut up about it.
