    Welding 3/8 aluminum with cost in mind

    First off I wanna say I had no idea what to title this thread with...

    I'm looking for a machine to weld some fairly thick aluminum with. Up to 3/8 of an inch is probably as thick as I'll need to go. I priced out a Lincoln 260 mig with a push-pull gun. It's a little more than I'd like to spend right now. I started looking at higher amperage tig welders and I was wondering what would be the best bang for my buck. Going with an older machine, no bells or whistles... but cheaper, or going with a new machine? I already have a 175 square wave that works great for thin stuff, I just need something with a few more amps for the thick stuff... . The work is mostly on rectangular tube, going to be welded in position and there's a fair amount of welding to tie all the tubes together. Just looking for some opinions. Thanks!

    Syncrowave 250. It’s a 310 amp machine

    There's a guy who's somewhat local selling an older syncrowave 250 with a liquid cooler for $3800. I can also get an Everlast 325ext with a cooler brand new for about the same price. Would you recommend the older machine in that case?

    Hell For 3800 you can buy a HTP221

    Ive seen used Syncro 250ís for 1500 bucks.

    My weed burner says Victor USA and the ability to pre-heat is an asset to EVERY welderator playing with thicker alumininimum....or a bigass chunk of cast .

    Those htp 221ís go for what 2400? Which is a inverter btw and inverters are known to brake much faster then a transformer

    Older ones usually go for 1800+ with bottle and everything making it turn key. You will wanna stick with the known to last brands.

    That's grossly over priced.

    My mid 90's syncrowave 350 with cooler cost $1800 including freight.

    My Airco 300 was $225...

    I'd find a used Lincoln 256 or Millermatic 252 with a spoon gun. You don't necessarily need a push pull gun to MIG aluminum.

    Yup. I seldom wire up my TIG any more. Too easy to grab my spool and plus into my Mm200

    I kinda forgot to mention that I'm in canada also... . Our maple syrup dollar isn't that great right now, so all those prices are CAD. However $3800 still does seem a little high

    For example the Everlast single phase 325ext on the American site shows $2799 USD... On the Canadian site in Canukbucks is $3700

    Re: Welding 3/8 aluminum with cost in mind

    FYI i have a syncrowave 250 at home and have welded 1/2" AL in my garage more than a few times. It will require a 100 amp breaker at the panel if you've got the machine cranked up. You will want to AR/helium mix when it gets that thick.

    .
    depends on amount of welding. obviously you can stick weld aluminum but most people know you need bigger rod for anything over 1/4" thick. 5/32 and 3/16" aluminum stick rod is harder to get usually special order.
    .
    for the same reason all aluminum welding requires relatively much much higher amps. if you use 1/8 stick rod usually weld starts are cold and its difficult to easily get a decent weld without some serious preheating. like if you Tig weld thick aluminum at 250 amps or more who could possibly think you can stick weld with a lot less than that in amps and not have lack of heat problems. and 1/8 aluminum stick rod is far too small to use anywhere near those amp levels.

    what's the thinnest aluminium you'll want to weld?

    John doesn’t seem like u know what your taking about 3800 is what a dynasty 200-210 goes for not a htp. And it’s a fact inverters will die long before a transformer. Look how many dynasty’s die. Just ask terry. Sorry John you are getting all defensive and feel this way. I’m just throwing out facts.

    I'll never understand why people insist on trying to weld heavy aluminum with $35 Chinee inerter soldering irons...it's like trying to go into the gravel hauling business with a four-cylinder Chevy S-10.

    Just because it can be done, doesn't mean you should try!

    So Terry uses his dynasty's everyday in a production environment. I don't care what machine you use in that environment, they all die and need repairs at some point. I'll take a quality inverter from Miller ANYTIME over any transformer machine no matter if they don't last as long which imo is pure bs. The weld quality is WAY better with the inverter technology versus a dinosaur transformer machine. Not to mention portability. To get the same thickness range from a transformer versus the Miller dynasty 280dx your talking being able to carry the dynasty by hand or using a forklift for a syncrowave 250. To each there own but I'm a professional and I'll take new technology period, I know what produces the results I desire.

    I think the more important point here is the OP started out looking at a MIG set up. TIG is going to be much slower for this job. Time is money and he will be much better off ditching the idea of a TIG unit and finding an appropriate MIG with a spool gun

    Anyone who had go after a cracked up aluminum dump bed would quickly agree

    1/4" stick electrodes and an SA200 would work. unless you need it to look good/hold alot of weight. then that'll take some serious practice and a preheat torch
