    Default Hobart Easy Tig

    Sorry. Misunderstood and thought you had the Viper already
    In that case I disagree - the Viper actually has more functions than what you have now - just less knobs!

    Grab a piece of cardboard and cut a 1" round hole in the middle. Place it in front of your welder with one of the knobs sticking through.

    Now you have the control simplicity of the viper
    If you want to change a different setting - just move the cardboard to the knob you want to set.
    Only ever one knob to turn - same as the viper!!

    Yeah that is an idea Steve it welded great on the basic setting i was told to use i would just like a bit wider puddle the current settings were giving a puddle around 7mm i would have liked the puddle to have melted a radius on the 4mm x 4mm sheet open corner weld without blowing a big hole

    Gazza, you are a salesman's dream come true. You love shiny new toys and seek them out in the hope that they provide the magic bullet that turns you into super welder.
    Seriously though, history will keep repeating itself until you develop an understanding of how the welding process works and how changes in amperage and arc length affect the weld.
    The Hobart machine that "automatically" adjusts for thickness etc is effectively the same as what you already have. That super smart one dial does it all knob is simply an amperage control. It may tie in with the gas post flow, but that really is neither here nor there in the scheme of things. I am unaware of the Hobart brand being sold in Australia now. They were once as my personal TIG welder is a Hobart Tigwave 250.
    You already know that you use AC for aluminium based alloys and DC for everything else, with the electrode on the negative pole of course. You don't need a new welder to produce the radius edge on your 4mm ally open corner joint, you need improved skill and possibly a few more amps. Dirty ally will always need physical cleaning, the cleaning width setting or AC balance is really only very fine tuning. In 30 odd years of TIG welding, my balance control has left the AC balanced setting maybe 5 times at most. Practice is what you need and you will waste more gas and material by not practicing than what you would use in practicing. The TIG process is very economical when it comes to gas usage and with a gas lens, you may even get as low down as 4 or 5 LPM.
    On the subject of Pulse Migs. A $1000 pulse mig will be nothing but trouble, particularly if it comes in a BOC (Bodgy Overpriced Carp) box. Secondly, while pulse migs are an excellent tool for ally, they will not replace a TIG. I will guarantee that a fuel tank built solely with a pulse mig will leak 99 times out of 100 and that fittings welded to a tank will generally leak if welded with a pulse mig (or a standard mig for that matter). Cracks in Aluminium boats cannot generally be welded satisfactorily with a mig, but TIG will fix them. In my experience pulse migs are at their best with new material in a production environment, they will extend the capabilities of a competent welder, but will not make a beginner competent. I can also say that some pulse migs have more knobs than the bridge on the starship enterprise.
    I know that you don't want to hear this, but it takes time and practice to be a decent welder with Mig, Tig or stick welding and you have yet to put those hard yards in. I won several awards during my apprenticeship and could well and truly hold my own against my peers - then I went an attempted my first WTIA coded welder certification. I had to practice and rise to the next level of proficiency. It took me a couple of attempts to pass the weld test. There is no substitute for arc time.
    I really want to encourage you Gazza as you've got the motivation to have a go, but you need to temper your impatient streak.
    I know there is some sort of roadblock that prevents you attending TAFE, but is there a men's shed in your area that you could access? A couple of hours with someone that knows what they are doing would be a great benefit to you and I reckon that once you have had the various functions and their effects demonstrated to you, it would be locked in your memory.

    Not too sure about welding class's Karl i might look into it but there is a bit to learn from an experience welder, i can DC tig that is quiet easy because its one dial, the mig and AC tig are where i need improvements, my brother inlaw is a qualified welder his fav was arc welding as i was growing up but he is no longer again and i vary rarely see him its a shame because as he faded from the scene i picked up welding last i heard from hi he was welding aluminium trailers for a coin

    i know your right and it all takes time and if i am to teach my self i will need to adjust the settings on the machines its just that its not 1,2,3 or 4 settings the settings are multiple combinations and variances its a whole heap to learn and remember when i only weld sometimes once every few months i just think the "simpler" the machines the easier it will be to learn and quicker to put in those learning hours

    the problem with my machines comes down to all those settings in my head i know those settings do something and if i don't learn or don't know what they are for i feel like i don't even know how to use the machine even if i can weld on pre set settings than it just gets to much for me and i always turn to looking for a easier more simplified model to use something that is basically learner friendly
