    Hi,
    Just a potential heads up.
    It is to do with DIY trailer and who welds on. I really think you should ask some questions in our Forum trailer section about this.
    If memory serves ,the registering authority may need some documentation on who welded the trailer. Info was stamped on a plate and this plate is permanently attached to the trailer .It was part of the inspection procedure .
    I think it is in the ADRs for transport.

    Before you commit to $ you need to check.

    Regards
    Grahame

    Thanks Grahame i just asked in the other forum

    to everyone subscribed looks like my vertical welding is improving this afternoon i cranked up the welder and thought i would try again welding vertical, the first past i was at 45amps blew a hole backed it down to 40amps on the line and it ran these welds with a nice bite into the metal i could see the pool melting the material

    the arc striking is quiet strange i had a good earth connection and i knocked off the coating on the rod to see if it were just me with the machine not arcing and sure enough it wasn't arcing bare rod steel to the bare metal i had to wait probably 8-15 seconds before it would arc again is this due to the VRD?

    these 3 pictures are vertical up welds at 40amps if i turned the amps up to say 43-44amps it was blowing holes, i did try a vertical down weld surprisingly it welded a bead it was a fast weld tho

    Hi. You are only just getting in the range of enough current.... the bottom bead in the right hand picture is getting closest.
    I think your arc length is still too long. It should be the diameter of rod wire core. That makes it more and more difficult the thinnner the rod is. But in the end it is just practice.....
    I've gone back to welding school (Cert IV in engineering) after hobby welding for 50 years - and learning lots of bad habits. I'm finding with 4 hours a week of supervised arc/plasma/oxy time, a lot of pennies are dropping that I never knew even existed. On the other hand, my hobby welding is now a pleasure, because I feel much more confident about success.... and recognise what I still need practice and supervision with.

    As an aside, I'm currently learning fusion welding of cast iron. That will be a future separate thread.
    Cheers, Joe

    Thanks Jhovel i think i just need more practice this is only my second i think day welding vertical with a stick welder so hopefully more learning to be done

    I find the stick welding a lot easier than mig i just need to find that happy spot on the amperage control or that particular day and i reckon i will be a happy camper, I'm sure it will all come to me one day everything will line up

    It's been a few years since a mate made a car trailer, but in NSW at that stage, there was no requirement for any listing for who welded the thing up short of production, from memory he just had to get a weighbridge printout. Probably would be a good idea though, with the strong chance to have bad mig welds, that might look half ok cosmetically tearing down the highway.

    These oil filled boat trailers, sure that's not oil filled then drained? If it's like some of the aviation uses, the intersecting nodes were drilled, a quantity of some sort of oil that left a waxy surface behind was added and sloshed around, then removed.....I'd guess Boeshield or similar might be used now....as it's no longer the 1940s.

    Strikes me as very odd this multiple swapping/selling of tools on this and previous threads - a bit of tafe evening instruction might go a long way after reading the start of this!

    Thanks Hutch, I'm unable to go to tafe mate for personal reasons, thinking of filling the trailer with SX-50 its biodegradable and mostly water
