    since you like some weld porn, here is another MIG beads run nice and hot although not as hot as the last, around 30 volt and 600 IPM and with .045 wire instead of .035.

    Re: Critique my beads (V2.0 on the bottle)

    Jee...s ! almost had an orgasm !!!

    Seriously I never used MIG, I have read about the absence of direct amps regulation, but I confess Volts and wire feed do not talk to me then.

    I will finish my 2G exercice. Beads until I run really straight left right right left . ANy hint ?(that is yet far better than it was; with 1° fixed shade #11 gold plated - 2° New pair of glasses just for working.

    I'd like to prop but have no support to put an anckle or a hand, so I just maintain the rod at its beginning, then all the rest with one hand (I am happy to begin to have a steady hand without prop)

    Prop is not as easy as it seem, often it restrain my moves. I noticed anyway that when propping, that is the welding hand that "learns" so if the body is stabilized one hand may suffice. the lead is heavy I need to hold it or to have it laid not far to suppress its weigh (even if only a few feet - BTW if the lead is falling free to the floor, I need to hold the stinger farther from the rod)

    My 1/8 beads seem to be a little large (without manipulation) but they work OK , I will try to make them thinner - I have not too much amps is not it ? (115A for the 1/8, no Arc Force)

    What you've head is right, with a few exceptions (most notably with the STT (Surface tension transfer) machine by lincoln and the LN25 wire feed suitcase (also by lincoln) which can run of CC or constant currant) wire feed welding has no direct amp control, it is a CV (or constant voltage) process, and so the machine keep's the voltage constant while welding by changing the amps, more wire gives more amps, and a shorter stick out from the electrode contact tip to the weld also gives more amps, while stick and TIG are CC which change the voltage to keep a constant amp, with a longer arc the voltage go's up with TIG and stick.

    for reference, in my first picture welding inside the pipe that is about 350 amps at 32 volts, to get the same deposition rate and heat input with stick you would need to run 3/8th in (8mm) electrodes which pretty much dont exist.

    Go clean up and bevel two pieces of metal and connect them. After all the point of welding is just that. Welds are like women. The backside has to look good too !
    Pads an MIG are an utterly goofy concept. Sorry for my redundancy but pads are for practicing drag and down with an electrode. Robotic movements. Nada mas.

    ARff !!! Sure, real project also more interesting than padding, I agree § May say I am more inventive with pianos and music, than with metal work, but there are a few things I need in the shop (and a gig for my padding an other welds ,)

    Something escape me, when I make a too tight arc, my welder send more volts to keep the amps level ? is not it the same as when welding ? Or do arc force raise voltage even before the arc is too short, making an arc that dig more ?

    I (possibly) wrongly consider amps as a pure data, to allow more amps, the machine may send more volts, correct ? (sorry for the dumb question)

    I am in absolutely no way what so ever an expert. I'm just a high school senior taking Welding 1. However, please correct me if I'm wrong but I don't see any signs of penetration. Granted you can't see the back of the plate to really tell though. Thoughts?

    I have one for every occasion. i use the cutter on the cheapie grinder because it’s lower rpm and doesn’t explode the cutting disks. That sucks when that happens. I put the grinders on my other 4 1/2” Dewalt because it hauls azz and is perfect for grinding. The metal is back slick again do time to get busy. I have plenty of access to metal, i just know if I wanna weld I have to prep. That’s part of the gig. Like I say, if ya don’t wanna grind and prep you’re in the wrong gig. It sucks, but it’s how it goes. All jobs have a sucky side of maintenance to them even being a waiter you have to do some prep in the kitchen. The more you accept the harder aspects and practice them the easier they’ll be so I grind therfore i am.

    See these heat marks by the clamp? That’s backside penetration. I build a lot of things, but I always run beads in the downtime. Practice is perfection.

    The only thing I’m curious about is with everything I use being multipass is if I’m getting a different outcome in the weld toes by welding over filler.

    But, really escape me, if you want to weld on your preps, why not do bevels ?

    Me too ! I also are have grinders (plus a metal brush on a polisher and a large 320 mm one !!! )

    If you like to grind, I suggest you by the 3m support for the cubitron II disks (the one in the middle) I was amazed by the efficiency of that abrasive, , it eat weld beads really fast and do not send dust as the grinders (way less) grit 36 , they say for that strong grit use the ventiled support that is a little crowned, the flat I have on the pic is more adapted for grits above 60 (they say)

    Good old straight boring pull. Until I get the crusty toes under control on the whips I’ll have to stick with old trusty for anything other than practice.

    The one on the top seem to have melted the base better than the first ones you did post.

    Re: Critique my beads (V2.0 on the bottle)

    The first welds to me dont look to havent penetrated much angle to me looks to steep. Dragging a bead on flat plate itl build. Whach the puddle watch edges wet in.

    Quit trying to make them look cool and concentrate more on solid sound weld.

    You mentioned the bob mofit guy.

    Put welder down and spend a few day's watching his
    videos

    Then burn burn burn, soon travel speed gun angle and even welder set up will come to you as natural as scratching your nose.

    Good luck and have fun with it.

    And get more scrap metal . Im a cheap as but id rather make puddles then waste hours upon hours of my life erasing welds

    They are all hot. Lots of penentration. The toes will crust up if too hot just as here:




    Bu I’d rather have penetration and be hot than not have it and be cold.

    It is simple for you to check, cut in two, etch, you will see by yourself.
