There's quite a few variations on the tme around now - I'm always a bit skeptical as to how good the weld is likely to be.

I'd be tempted to give it a go though. The only problem I can see is that, as in the video, when you heat up another part of the metal to do another wel, any previous welds nearby will melt and detach.

Why not just go to BOC and buy aluminium fluxed rods or a tub of flux and rods ? this is what we use at work

I've used similar for making tees in alloy hoses - they've never failed despite my rubbish technique! It takes a bit of practice and you need to get the metal up to temperature but it's not hard. As StevieB says you have to be careful not to reheat any joints you've already made.

There's a supplier on eBay I've used who's really helpful. I'll try and dig out his details.

I've used HTS2000 aluminium braze to good effect.
If you are joining or filling large sections you really need a good heat source.

It can be used on most alloys including high magnesium content alloys.

I built up a missing portion of lug on an alloy upright, it's still holding after 7 years of competition.

I used the "original" ones IE the Technoweld brand. Blooming strong. Tricky for pieces where you need multiple brazes in a small area but hey...

A blow torch with a smaller flame would be easier then you have more control i would have thought?
