You will need aTIG welder with an AC setting, argon gas (don't use a mix) and a suitable filler. Use either a pure tungsten electrode (or a 2% ceriated if your welder has a square wave function).

If you can get a welder with a foot pedal it makes it much easier as you can ramp up the power to get heat into the weld at the start and fade it out at the end of the weld.

If you have ever gas welded (oxy-acetylene0 then you will have some idea of TIG (generating a weld pool and using a fill wire).

As with all thing, practice makes perfect. Why not try an evening class (new baby permitting!).

Cheers matey, hadn't thought of evening classes... maybe they'd let me bring bits in for practical lessons

I am sure they would. Failing that, if you have only a few bits to do, then get friendly with your local college....they might weld them up gratis

you can get a mig welder to alloy weld but you need a good welder that has a lot of adjustability

Only really good for heavy-ish alloy. You can get the spool-on-gun type or a push-pull system (spool on the welder body with a motor on the gun pulling the wire through). Both types are a pain in the butt to use....great for heavy sections but not so good for small pieces. Plus the weld beads are very difficult to get neat and tidy.

more hassle than they are worth IMO for small type fabrication.
