    Just trying a bit of vertical up mig welding.
    I have a couple of bits of 10mm flat bar in a fillet.
    Settings I have started on are 7.5M/M WF and 19.5V on 1mm wire.

    I'd rather get some advise on before wasting any more material:

    Just knocked my wire feed down to 6.5 and had another go. Took a little while to calm down and settle into the pattern. What do you guys think?

    A few more short runs with 6.5 wire speed.
    This one shown below is probably my neatest but I used more stickout to get more comfortable which drove the voltage up to just over 20V.

    Spend more time at the sides
    Quick across the middle it will take care of itself when you get comfortable with the technique
    Take a smaller jump up everytime you move up
    Get comfortable and relax into it
    it’s not a race

    What technique are you using
    Single pass triangualation

    Two pass
    Hot root stringer
    Zig zag cover

    This is all single pass triangulation.

    Not the best but here’s a
    Couple runs singlepass triangulation
    The effect of not spending enough time at the sides

    The bottom part very little time
    Middle 1sec approx
    Top 2sec approx
    19v 6.5mpm 1.0wire

    I was taught to put a root pass in first before weaving over the top on 10mm plate.

    The root will help with your weave as the root material gives a flatter area to weld over.

    What way are you applying the root pass with mig vertical down??

    Can a stinger be done with mig I thought you could only do vertical up with weld manipulation ie tracing the front edge of the puddle, triangular motion z wave etc etc??

    I was taught vertical up for the root pass and the weave. I'm no expert. Just passing on the practice I was taught.

    Someone who knows what they are talking about be along in a minute I'm sure.

    Hi Matt
    Try this. 5-5.5 m/min 19v.
    Should give you 100-115 amps with a short stick out. Hold on the corners for a smidge then move over hold move hold move.

    Yes you can do a stringer but with slight manipulation to keep the toes in blend. It’s pretty much a stringer.

    100 amps 19v
    Stringer root weave cap.
    I’m no expert with a mig either but I dabble for a laugh when the need arises.
    The important thing is keep the torches angle pushing up and watch the root bite in the corner. If you weave too heavy on the root you’ll get lack of fusion where you need it.

    Bit of trial and error. Improved things with a little less hold time
    The root was pretty much straight up. A tiny bit of a wiggle to get edge wet but really aimed that wire into the corner.

    @MattH I'm about at the moment if you wanna hand with settings can provide some scrap if need be my backs still fluffed but I can still weld and point you in a good direction

    What sort of a mess. Throw a few details out with some pics

    Depending on plate thickness, 100-130A

    Thanks mate, it might be good to spend a bit of time on the rig with someone who can drive it properly. I’m hoping to spend a day in my workshop over the long weekend to tidy up a bit and do some more practice runs.
    You’d be more than welcome to pop over, have some brews and show me some techniques.
    @HughF fancy popping over as well?

    Regarding some scrap steel, that would be great. I have some stock but it’s being wasted on practice runs.
