    Love your welding vids John , could watch them all day, I’m a paraplegic permanently wheelchair bound struggling to get a job or an apprenticeship doing welding so I bit the bullet and purchased a Michigan 130 MIG welder to learn on, safe to say I love it, your vids are definitely helping me out .

      There are perfectly able-bodied people who waste their entire lives by giving up before they've done anything significant (or menial). Good on you for making use of what time you have, regardless of circumstance.

      John, you said you don’t need an expensive welding table. I’m happy to hear that, because I’m using an old galvanised water tank.

    This channel just keeps getting better and better.
    Thanks, John.... I'm a mad small workshop guy.... In fact, I have been welding today myself. I find that making in general is so therapeutic and keeps me feeling good about who I am.
    I can't write computer programs nor understand the stock market, but I can join metal with electricity and also make quality items from wood.
    But welding is my first love. In fact, I have a thing to share. I was trained as a welder in the 1980s, so I used a nod to close welding shield. Now, I have a self-darkening shield. I still find myself having a little spasm as I commence a tack or weld as my brain won't allow me to remain still.... I wonder how many others suffer like I do.... I actually laugh at myself each time I do it.

    As a boilermaker back in the day WIA 6012 were always better than a satincraft rod especially if your welding experience was minimal and you don’t get the slag inclusions. Now if you really want to get a hard on try an iron powder rod, they really lay it down and the slag self releases. Cheers really enjoyed it

    'Guilty, your Honour",... I have ( sometimes ) rushed a little job and did not take the time to bevel the joint. I knew that was wrong,.. I was lazy at that time.
    John is correct,..an 'un-beveled' joint will, more than likely, break or distort.

  • @dfross87

    Good little project, John. I won't do it because I already have a portable vice mount (goes into a 50mm hitch receiver), so I agree: a portable vice for field work is too handy not to have!
    Definitely looking at that vice though. For the price I'm sure I could find a light-ish duty use for it.

    in furniture making we use self centering drill bits. am tempted to get a welder for the very odd small job. though it may end up being cheaper just to get it done. the only thing i really want is to make a frame to sit my tablesaw on that has castors attached for easy moving.

    Good job John, you definitely picked the right profession for your personality I think engineer through and through
    I think I’ll buy one of those vices they look bloody good and the 4 1/2 inch is only 50 odd bucks…….
    Regarding the video, I like to see you tack things to hold it down, but I always thought the purpose of the tack was simply to stop things moving as the joint heats up and expands from one end to the other…… It all ends up skew wiff…… good job

    The only welders I've used that actually deliver the current they say are usually well over a grand. Modern 1K ish welders are usually pretty good but even as far back as 5 years ago it's only really welders that retailed close to 2K AUD that get even within the ballpark of what they claim. With chinese welders you can take about 30% off the top of their rating and about 15% when around the middle for 100 amp rods i find 110-120amps for chinese machines is usually about right but it does depend greatly on ambient conditions and how well your home power copes with the load in terms of frequency and voltage.
    One of the most expensive welders I used was a small 170amp mig only kempact. They were close to 2K last time I checked but their value is being able to weld well off a very dirty power supply without dying, behaving wierd and usually don't hurt a generator that can only just supply enough power.
    These cheap inverter welders are great but they can make the learning curve a little steeper, especially with stick welding as I'm constantly fiddling just a few amps here and there as they get hot whereas my way more expensive WIA ACDC Tig/ARC welder I barely have touch and feels easy with arcforce, hotstart and other functions but I find myself leaving that machine as a stationary TIG station as it weighs a tonne and I don't like wheeling the gas lines and massive tig torch cable around.

  • @trevormustey4418
    @trevormustey4418 ปีที่แล้ว

    The only tip I can add to this when welding with stick, is to keep your visor down after you've finished playing Jedi light sabre's, due to slag having the uncanny ability to launch itself into one's eyeball!.

  • @giddyup3451

    Interesting vid John. Nice one. Much better than the EV hate vids, but will probably generate less $$s for you. While you're talking about fasteners, can you talk about wheel studs/bolts. Lots of people seem to think they're there to hold the weight of the vehicle not bolt the wheel to the face of the hub. Fasteners aren't there to take the weight of anything, just to clamp to faces together.

    Satan was riding a Harley ... now he drives an S Class? Whilst that is probably true, I would imagine to take full effect of the flame thrower he'd have to take to the roof with his plasma cutter, or maybe just a recipco saw . I suppose that would stuff up the questionable warranty and probably negate any consumer law claims. I suspect my imagination has gone a bit far at this stage.
