Aluminum welding.
few pointers you need to learn.
1: its AC not DC welding, thus, a half decent welder will set you back ~3.5k.. yes you can get cheaper ones, i said half decent.. I want to spend 5k. But the missus has other ideas.
2: preperation is half the job
3: correct rod selection is half the job
4: Alu melts from the inside out. Knowing this is actually sort of important. This means think of your welding pool as a "volcano". It is only a smaller puddle on the top which you can see, but there is MUCH molten goo in the middle you cant see.. This is why preperation is VERY vital.
5: steady hands is yet another half
With all these halves combined you might make something useful.
As for sneezing,.. exhale as MUCH as you possibly can when you know you will sneeze. then try to hold it thru the actual sneeze action. You tend to hurt your throat / lung a bit, but you dont actually move / shake the weld.
yes its an actual technique i have used.. No its not actually used much, but it is used.
Personally i use a breathing mask. Breather on the waist belt.. Clean air.. no fumes,, no sneezing.. thus no cavatation of your lungs.

I guess you're talking about TIG/stick welding ... I am a mere mortal who uses a home MIG after a fashion, so far most of what I've done has survived! I didn't think it'd be too different to welding MS so I thought I'd have a crack at aluminium and bought a reel of wire and a bottle of argon - I ended up having a very frustrating experience!
I've seen these kits which you use like brazing rods - heat the job to 350-375C with a torch, clean and de-oxidise with a stainless steel brush then tin/flow the filler in from a stick. Are they any good cos that's about my level of ability

TIG is like gas welding / brazing. If you learned with that first it's just a matter of following the steps Quan-Time suggested (I was only half joking about the sneezing part). Keeping the impurities out and getting the right "temp" is the key. Once the pool starts forming, it's just a matter of learning the feel.
His beads are very good though, mine look more like old chewing gum stuck on in series. Sorta like the Yamaha factory robots.

We just spent about 10K on a new mig welder at work.You just dial in your metal thickness and it automatically sets everything for you.You can manually adjust everything aswell if you want to ,but for plods like me it easy and can actually make the welds look good.It makes nice jobs with aluminium or ferrous metals.It is also a stick welder, if that takes your fancy.
As for the aluminium soldering kits that Greg is talking about, they do a nice job as far as looks go, if you prepare it properly, but there isn't much strength.
You would think that with access to CNC machines and all the machinery under the sun, I would actually do something, but since I found out that a Harley Sportster is my ideal bike , I seem to struggle with motivation
