    I was always under the impression that the first two were tensile strength, then 3rd was the positional usage of electrode, and last was to do with the composition of the flux.

    This is correct.
    70(70,000 psi of tensile strength)
    1= all position electrode.
    ?= type of flux coating. (8 would be Fe powdered low hy)

    That's were I get puzzled because a 7018 generally does not go v down but a 6011 does (but then I actually have some 7018 certified for V down).
    Are the electrode codes not a bit narfed up as over time manufacturers bring in new or different stuff but code them the same? Let's face it there is a massive difference in say 6013 vodex and 6013 no name badged as super six or Halfords etc etc

    Remembered reading something on here some time ago. Here's the link. Will make alot of sense as to why differnt electrodes perform differently. But you'll also find the likes of super 6 don't put the same research and development in as say murex, bohler to name a few.

    But you see 1 isn't always all positions when you include v down

    I think v down is like an add on, most the time it will specify on the packet. I've often wondered the same thing as yourself. Other than open root and thin sheet I can't think of many other uses for v down.

    Try going up on 3-6 o clock on dozens of welds. Or sheet piling when your down a muddy dark hole.

    By all position what is meant is vertical/flat/and overhead. It doesn't specify the direction of travel just the fact that that rod can produce a joint in that position.

    Now you guys have said that I realised I was getting it all fuddled up, I had read that before and actually have a poster up in the workshop explaining the electrode designations.

    You should speak to Matt about the reps position in your area Brad.
    You'd have no problems flogging those blutorange boxes mate. :clapping:

    Got some nice results with the S3 this evening. More practice will get the consistency.
    Etched some 6mm fillets. Few issues to sort out but nothing that cant be fixed. Tbf I was probably a little cold and in twinpulse, which I imagine has given rise to the lack of fusion at the root on the first run (right) and the pore.

    @Hood have you etched any of your welds with the Phoenix?

    No, think the only one I have etched that was Mig was one of the first runs I did when I got the R-Tech.
    The EWM is not at my workshop at the moment, I left it up where I have been fitting out the boats as I will be back there next week sometime, so can't do a test this weekend but will try and get a test done soonish as it would be interesting to see.

    Cool. Just use oven brite or similar as long as it contains sodium hydroxide it should etch. Left it on about 10 minutes.

    I've bought some of the Tweco croc earth clamps this week. Much heavier build that the generic tin ones.

    I have been using Avesta Pickling paste, seems to work but maybe the oven brite would be better?

    Best earth clamps are tweco ones... I imported some from the US last time I came back. They are available from rapid.

    I use stinger-v electrode holders, they're superb but I prefer the crocodile style over the twist style.
