I have had plent of practice welding alloy with the henrob but never really got the results i expected
Make sure you preheat the alloy on a bbq or similar and use the flux they recomend.
This was the best result i ever achieved

Yep, been using it for 3 years, works great on SS and mild steel, Alum is quite difficult, TIG alum is much easier.
Henrob is beautiful on sheet metal work/thin mild and ss. Alum also but difficult, the claim is Henrob welds are much more pliable/not brittle as other welds are, flat weld beads and minimum warpage. Thick steel like quarter-half inch is difficult, can weld with biggest tip but looses its pin point accuracy. If you�re welding your Torana patch panels Henrob is prob the best, use number zero or 1 tip. If you�re welding alum it�s probably the worst particularly for thick stuff.
I�ve seen guys weld alum fuel tanks for choppers on TV, these applications are nicely within the Henrob capability due to pliable weld and the weld bead flatness and deep penetration, I don�t know about TIGing steel but TIGing alum means the weld stays mostly on top of the material, the Henrob penetrates deep in alum and steel, almost creating one piece which is why Hot rodders and chopper builders use this.

Yep, thats about the result, you dont get the nice stacked plate look like TIG alum

I don't understand how you came up with that? A TIG is just an electric oxy welder, so if the weld isn't penetrating, just turn it up. If the henrob isn't set up properly it wont penetrate either.

I've had "some" experience with a henrob torch but just don't see the benefit from a classic oxy for panel welding. I know the henrob is a bit easier, so maybe that's why people like them? Oxy welding is fairly easy, and like you say, the welds are nice and soft and can be beaten and planished smooth. You don't HAVE to use a henrob to achieve this.

As for chopper and hot rod shows using henrob, well I've never seen it. American Chopper, American Hotrod and all the Rides I've seen have used TIG.

Having said all this, any sort of welding is fun, so just get in and give it a go no matter what set up you can get your hands on.

Hey Bart, on a more important matter, was it fairly expensive to put a manual behind the VH nissan motor? I'm trying to talk my wife into letting me take the auto out of the firebird so it's not a pansy car : )

Did I say that?
I guess I meant the technique with applying heat and feeding the filler.
The claim is the Henrob will penetrate more and have a flatter weld bead compared to the Tig, the Tig will surely penetrate but the weld bead will be higher slightly and not as smooth from what I have seen and read.

The gearbox was $2000, its a RB25t gearbox. The adapter plate was $350 inc flat head bolts, maybe the bolts were extra?

I remember welding training when I was an apprentice. We had to weld aluminium with an oxy. Bugger of a job as it doesn't change colour like steel.
Been wondering about those Henrobs. I have to do some serious panel joing on one of my HK GTS's. I wonder if it'll be better than the MIG or TIG I have? I have to do major joins around the wheelarches and join across the C-pillar.

Tig is definitely good enough, its what most guys use if not a mig. The Henrob normally makes smoother flatter welds, but i think the Tig is almost there anyway.
