  • where is all the videos,,,,AC,,,, stick welding,,,buzzbox ???

    Where is all the videos? I been searching, nope, can't find them.
    I am welding a new lathe bench, and what I have is a little AC, 'buzzbox'.
    Every video I look at has a story about the Lincoln tombstone, briefly, then goes on to DC, reverse polarity, adding on a TIG torch, et. al. And so on with talk on DC rods, inverters, and TIG technique.
    Well hells bells, where is the 'technique' for straight-up damnit AC stick??
    In a similar time frame of technology you can find info on the old South Bend lathes, Myford, Logans, and so on.
    Well, where is the info on the welding of the same time frame???
    Really?? Was there NO structural welding with 'AC stick' back in 1950??
    Was there NO welding inspection back in 1950?
    Was there NOBODY laying down pretty beads with AC stick back in the day??
    I welded with TIG many years ago, and that machine had all the gegaws and doo-dads for TIG, very nice.
    But that is not today, all I got is a AC stick buzzbox. So I am reaching out for some guidance.
    This machine is the type you physically plug the lead into various positions for amp changes, not even the variable hand crank for amps, the simplest of all.
    This machine pre-dates the so-called Lincoln tombstone.
    Am I incorrect to think that IF a man can turn out good parts on a old manual lathe, then his counterpart man can turn out pretty weld beads on a old-school AC stick weld??
    Where is the guidance on this?? (or videos)

    Dunno, but as far as I am concerned, the simple AC, as long as you use a rod that works with it, is pretty easy. And, it will weld to the edge of the plate, where DC will often "blow" off the plate and stop short. Seemed forgiving, and it "welded soft" where DC "welded hard" in terms of what it was like to actually do.

    The basic tombstone is an AC welder, so..........

    In class I had no trouble doing decent welds, although penetration was not as deep, they looked good, and the bead was OK, and melted into the two pieces of base metal OK. I think if you just watch some basic technique stuff for DC welding, you will find that AC is OK too. Most of the same stuff applies, except it is easier to get a good weld. (you can get a bad one also with any system)
    CNC machines only go through the motions

      7018 (baked if necessary) runs fine on AC. If you are welding ok, and then your are not then your buzz box is getting to hot. Go get a cup of coffee, do some cleanup for the next section, and then when you come back to the welder you will find it welds good again. Doing some 6" well casing on my little Lincoln some years back found I could weld half way around and get a good bead pretty consistently if I let it cool off in between.

      *** I always wanted a welding stinger that looked like the north end of a south bound chicken. Often my welds look like somebody pointed the wrong end of a chicken at the joint and squeezed until something came out. Might as well look the part.

        AC stick is just fine, same as DC. Maybe some different rods for that, but it usually isn't critical. I have one of those red AC Lincoln boxes, and I usually do 6011 with it. I also have a DC inverter that I run 7018 with, but I can do that on the AC too. I find DC a bit easier to control, but maybe thats just me. I got spoiled by the big machines at work.

          A few videos picked somewhat at random after a very brief search. I can't vouch for the quality of all of them, but there are tons more out there if you poke around a bit:

            I think you are looking for information specific to the welder, when it's really information on the process that you want. You want to search for SMAW AC welding.

            A good starting point is the information from Miller

            https://www.millerwelds.com/resource...ding-technique

            https://www.millerwelds.com/resource...-stick-welding

            And they have a lot more.
            At the end of the project, there is a profound difference between spare parts and left over parts.

              So, do I ignore all the discussion about DC?
              Since I am ONLY interested in straight AC stick welding, does the talk about DC arc length, DC penetration, spatter, DC cutback, DC crown of bead, does all that still apply to AC?
              I think the guys doing the majority videos are trying to show off their shop or welds by using DC newer machines.
              Too few of them doing it old-school.

              They will gladly tell you that ac is better at welding dirty materiel, but NONE of them show you how to burn through dirt, rust, paint.
              Show me that !
              They all start off with shiny pretty steel then proceed to switch to DC and lay a bead, they're cheating as far as I'm concerned.

              How do you fill a gap? What if your fit-up ain't just quite right?
              Show me that!

              How do you burn through mill-scale,,,show me that !!

              My machine has amperage 'steps', it is not infinitely variable, how to I run the bead 'in between' steps?
              Show me that !

              These guys making videos are not telling you the 'technique' for all the things that matter the most.

                    No, don't ignore all the instruction about DC, because it's the same process, just slightly different rod selection. AC you can run anything 60xx, it's best to run 70xxAC rods if you want or need LoHi.
                    AC is better for burning through trash and rust out in the field, and you get less arc blow in corners than DC. However, DC is much nicer to weld with, it's smoother, it's easier to reduce porosity with and welds cleaner.

                    You could also do what I did years ago and add a rectifier and polarity switch from a junked welder , or if no junked welders around, buy a 200amp rectifier bridge and heat sink off Amazon and wire one in. We're talking less than $50 and all the parts will easily fit inside the case on Lincoln tombstone.

                      I bought some 6013 and 7018AC.

                      this machine was gifted to me a cousin passed away. I just got 220v plug in the garage, and I made myself a long 220 extension cord to reach the door,

                      I been using 1/8 rod and plugged in to 118 amp setting

                      this a decent video,

                        Just a musing...
                        It seems I am just naturally better with welding AC, be it 6011 or 6013
                        than I am with DC welding 7018. I never get those dreaded slag pockets,
                        maybe because I tend to keep a tight arc length. But for whatever reason
                        I most always get pretty beads with AC welding.
                        Everyone talks like you gotta have a DC welder, but I think it is just people
                        repeating things they know little or nothing about.
                        The best advice is, get a welder, any welder, and practice.
                        Make it happen and have fun.
                        Get good enough, and some day you can weld water to wood.

                          What Doozer said.

                          6013 is called farmer rod for a reason. Grab some 6013 and start welding with your buzz box.

                          Beginner welding is all about practice practice practice. Videos are ok, but you just need to start practicing.

                            Filling in a gap is the same regardless if it's AC or DC . Same for mill scale, it's the same regardless. What weirdscience said about controlling the arc is true, and what Doozer says about getting practice and "arc miles" is very true. Full disclosure, I welded for a living since 1992 , had 2 yrs formal training before that at Airco.

                              Where does the rectifier bridge go?
                              put it in the input side of power, or,
                              put it at the transformer output?
