    Default Tig Welder

    Hi all. Looking at buying a new Tig Welder to make an aluminium tray.
    The unit I am looking at is a UNIMIG.
    It's not cheap at $2000 but seems like a very good unit.
    What are people out there using?

    UniMig isn’t too bad. Middle of the road stuff but plenty good enough for the guy at home. Make sure it is AC and HF (high frequency) if welding aluminium and at least 250 amps. For that price I assume it would have a hot start function that help a fair bit and important for aluminium welding, a downslope function to help prevent crater cracking.

    Fronius, Kemppi, Esab, Miller are some of the high end stuff but you would be looking at 3-5 times the price.

    Do you have a model number?

    Is it this?

    More versatility in the future as a ute tray might be just the beginning.

    Spend the extra and get a quality torch with trigger. You don't want to be lift starting with aluminium welding. Constant tig welding 150amp + you will want a water cooled gun

    Something easily forgotten too is to make sure you have a 15amp circuit to run it off.

    I assume you have welded aluminium before but as a shopping list reminder:

    *Zirconated tungsten - 2.4 and 3.2mm for what you are doing. The 3.2 when getting 150+ amps
    *2.4 and 3.2mm collet sets. They do wear
    Long and short back caps
    *A range of cups. 5, 7 and 8 would be good using 8 as default, smaller for tight corners
    *2.4mm 5356 filler wire
    *Stainless steel wire brushes to remove crap and oxidization
    *Good quality tig gloves for feel of filler wire
    *when it comes to cutting and grinding try and use disc with cutting teeth such as used in woodworking as typical cutting and grinding disc imbed particles from the disc making it crap to weld. Aluminium die grinder bits are a worthwhile investment too.

    Good luck with it!

    Thanks for your advice mate.
    I am diving into the deep end.
    I have never welded aluminium before, but I am going to do it. Paying someone $100 an hour will add up very quickly. Im thinking a TAFE course at night will get me going.
    There will be will be swearing and mistakes, but I'll do my research and go for it..

    Definitely do a Tafe course if you can. Aluminium tig welding is a higher level skill compared to mild and stainless. Understanding the setup, consumables, weld techniques especially feeding the filler wire and current or heat input is different. And of course Tafe fees leave you with skills you can always use unlike per hour rate for someone else to do it.

    for my certificate .. I did a TAFE course many moons ago (3 years of night school)

    DEF worth it as they teach you all types .. plus cutting and stuff like spark erosion too

    Thanks boys.
    That's a long course Smitty, but like you both said, well worth it.
    I will enquire shortly about a course..
