    Go find something kicking about that has been professionally welded, like a trolley stand (hint!). Look at those welds, and I'd be surpised if they weren't done with a mig welder running gas. Just clean and neat.

    Actually, your welder running without gas isn't even a mig, since the ig part of mig means 'inert gas', and you aint got none of that.

    I think that wire usage is reduced when running gas, but I wouldn't bet money in this case.

    To weld ally, you need a welder capable of doing it (Ask Grahame), you need the right gas (straight argon, I think. Ask Grahame), the right wire, and to know what the heck you are doing. Most folks seem to think ally is something anyone can do, but there's an awful lot of fooling around to do simple weld on the stuff. Once you jump through all the hoops, it is doable.

    Ally with no gas, I dunno. Ask Grahame.

    If West Oz is really 10 years behind, then you should have no trouble finding somewhere to sell you gas. Used to be going and getting gas was an easy thing, now they make you do all kinds of interesting things to get what you want.


    The short version of all that (and I know you don't do short) is that gas makes your welds much nicer to look at, and no cleaning up the weld area after you are done. Well wroth it, if you can honestly justify the cost of gassing up your mig.

    Not 100% on this but will be in a few months as I need to gear up to weld Aluminium......got this big Alaskan mill to weld up you see.

    I think you can use Argoshieldlight to weld ally, but you are much better off with pure Argon. You also need to change the wheels oh the feed motor. The ones for steel have a serrated V-groove which is too aggressive for the softer ally, so they need to be changed to exact fitting (to the wire diameter spec) with a curved groove. The liner of the trigger tube also needs to be changed to a much smoother and forgiving one so the Ally wire has a nice easy journey to the tip...thats all I know for now.
