One local yard is using a couple of the cheap inverter units with the hand spools attached, and are quite happy with it.
And the welds look just like tig, with a good operator pushing the trigger.

Hi all, Can you weld aluminium using a mig welder?
and if so how?
thanks

It's hard work with a hobby type Mig, you really need a 4 roller industrial machine with serrated rollers a different liner and pure argon.

You can get a special MIG spool gun with a small spool of wire feeding only 6 inches rather than the normal meter or two.
Still won't be as neat as TIG.
that is a good link, lots of infromation.
Tried it a few years ago, then purchased a TIG.
It is almost impossible to get a decent weld from a hobby machine IHMO, it is possible to stick two bits of ali together but the weld will look poor
and is no good for anything containing fluids. So if you are planning a fuel tank then forget it.

I'm not a particularly experienced welder, and aluminium welding seemed a bit daunting, so Ive just got some of these.
HTS-2000
Haven't had a chance to try them out yet, but I probably stand a better chance of getting a good result than I do with a TIG.
that soldering stuff is pretty good, I have the durafix type stuff and I have soldered loads of non critical parts with it,
I thought I had pictuires in my album but can't find them, will look at home for them.
the thing is that peel strength of the joint's is not really strong, so for large seems I would consider soldering it together and then covering
the whole piece with GRP of better carbon and epoxy. simply breaking a joint is a whole different story it's pretty strong stuff.

They build aluminium boats with spool in hand guns. Hook 'em up to ac/dc tig power units to get the power.

Hi, has any body use this type of welding,
Link
thanks
stuart
T.I.G welding ali should look something like this
5% silicon rods flow nice but not quite as strong as 5% magnesium
mind the fumes though

Plenty it's also called Lumiweld/Technoweld, more like soldering or brazing than welding, but good for smaller nonstructural work.

There's usually a guy demonstrating/selling it at the kitcar shows.

hey Matt, is that this one?
and more importand did it stay in one piece?
GSXR 750 TBs and manifold
the durafix and lumiweld stuff is the same I've been told don;t know whether this is true,
there's also a german company completly specialized in alloy soldering http://www.rexin-loettechnik.de/

Hi all, i recived the rods today so i am going to have a crack at making my manifold today.
i post up some pics once i have done the welding.
stuart
Here is mine go at it.
