    On the trailer, i have most welds done, but the few that are on the bottom of the rails i just cant get there. I burned through it. What is the best way to stick weld these seems, and what is the best electrode to use??

    First I must say I am not a welder, but I have stayed at a Holiday Inn.

    Is your buzz box AC only or AC/DC?

    If you have the option choose DC. 6011 or 6013 are all position electrodes

    That is a really good article. wish i could see the pics though. I was looking for info online for welding, but i guess it is called overhead, rather than upside down welding ;)

    I only have an AC welder. :(

    Thanks!!

    i'll second the above. my cage looks right nice from the top, but the parts people acutally see are booger welds all over the place. if you can flip it over somehow (like say use that bellview i think i remember yout alking about) it would be a whole lot smoother in the long run.

    as for technique, i tend to go for sitting underneith it and looking upwards toward what i'm welding... but off to the side slightly so it drops down my shirt sleeve or on my hand. not wearing gloves only adds to the atmosphere.

    6011 with the 'Stacked Dime' Tech for over head and vertical up. I only had an AC Stick welder until last year. This allows you to get a little hotter to get good penatration and not burn through.

    it might be kind of hard to find in your area,but give it a try,7018 AC.its made for AC machines.make sure it says "AC",if it sthe regular 7018 it wont work as it should! it might be hard to find but it is out there.go with 3/32,hope that helps.

    Yup, 6011 or 13 --are you using 1/8" rod? I was struggling with Putt Putt's DC onboard welder because my rod was too small and blobbed off (welding term) due to heat melting the coating too fast (base metal too cold). I took it for granted that it wasn't powerful enough to use 1/8" rod. I was wrong and found the 1/8" heats the base faster and melts the rod slower but you have to speed up or do short "bursts"

    So, what they said above... essentially do a series of short hot "spot" weld bursts and stack em'. I like 6013 and 6011 the best. 7018 lays down nice but I don't think I ever welded overhead with this rod.

    use dc neg for out of position (anything but flat). i find that going slight colder (100 amp on 1/8 rod [instead on normal 125]) works better for me.

    Overhead welding is a learned teqnique (kind like spelling). I used to clamp a chunk of plate to my welding table and lay on my back to practice.
    Don't attempt it without the proper gear. Use a welding coat, gloves, helmet, and some sort of ear protection (slag/spatter hurts progressevly worse the farther into your ear it goes).
    Any of the rods mentioned will work well. The hardest part of overhead welding is knowing when you're going too fast or too slow. That is why I would at least practice first.
    Flipping the trailer over would be the best way to insure a good bead if you have the means.

    I would, as stated earlier, go with the 7018. Do not just flip it over, becouse you are only cheating yourself. Not everything is capable of being flipped. We use 7018 for about 97% of our welding at work (mostly structual, on concrete wall panels) and it is a great rod. Less likely to burn through than the 6011. Also I would start about 90's -100 amps. Start low and practice on something about the same gauge. Good luck. Zach

    You fella's are amazing. I have had limited sucess in this area. I can stick two pieces together this way, but it ain't pretty. 6011 is fast freeze, and I don't like using that rod, except when necessary. 6013 is a nice compromise, I have used lots of it. My all around answer for overhead welding (if metal isn't too thick) is MIG.

    I can even run a fairly even bead overhead with this little welder.
    I will admit that the stick is WAY stronger, and you can actually get penetration. I still like my little miller 130.....
