    Vineyard - drill pipe end posts - do I need a big MIG for this?

    Hello Folks,

    I will build end post supports for vine rows with 2 3/8 drill stem and I already own a Lincoln AC225 and a small Lincoln Weldpak 3200HD MIG (can weld up to 5/16 slow). My question is with 56 of these supports to build is it worth it to add a bigger MIG like a Millermatic 252 or equivalent?

    Thanks!

    My experience with drill stem is it seems to build up a magnetic field in it which will make welding pretty frustrating. The stuff I dealt with was difficult torch cutting it as the slag had a tendency to be drawn back in the cut and would take a sledge hammer to break the joint apart. Your AC welder would be your best bet to me.

    .
    math
    56 welds
    stick weld say 2 minutes each
    small mig 1.5 minutes each
    big mig at 1 minute each
    .
    so assuming say 1x56 with big mig saves 56 minutes, not calculating cost of rod versus wire and gas
    .
    so you want to buy what a $1000 to $2000 welding machine to save what 56 minutes ??

    I was thinking the same thing

    Id just use the 225 and be done with it.

    And if he runs 6011 to stick these together, he may actually save time by not having to prep the metal.

    If the pipe is magnetized then an AC machine will be your friend.

    Either will would work for me. IF you do a considerable amount of work using pipe I would consider a nicer AC/DC machine with 6010 and 7018. A Miller Thunderbolt or like your Lincoln AC one but with DC. DC runs smoother.

    Depending on your location you may find something for $200.00. I've seen AC machine sellers trying to get that much.

    Im sure you already have your answer but mig outdoors is a pain in the backside your gas blows away in a tiny brease, drop the gun in the one puddle on the whole property and have to change tips mud and mig do not go together
    And that pipe is almost always dirty inside . unless im putting on over 15 lbs of rod i will not pull out the ln25, stick just works
    Do not argue with an idiot. He will drag you down to his level and beat you with experience.

    Get a box of 6011 and get at it.

    there is NEED and there is WANT
    .
    many adults buy stuff that are basically adult toys. most successful businesses do not get new equipment unless the total actual costs are calculated to determine time for payback. if it takes longer than 5 years to pay for equipment often ts just rented. many jobs sites rent welding equipment by the day or week.

    As someone who has actually cut and welded a fair amount of drill pipe consider this if you like.

    Drill pipe is 4140 or similar alloyed steel. 6010 or 6011 will be very brittle welded to drill stem. Perhaps a root pass but then 7018.
    I've had to go back and re-weld pipe that someone else had welded with 6010.

    I'm not saying 6010's won't hold but 7018 is MUCH better choice. There is a 7018 especially for an AC machine.
    Also preheating will help with the brittleness.

    Sometimes drill pipe is magnetized. You can beat it with a hammer. That may scatter the magnetism.
    Putting the ground on the opposite end may work. Or coiling the ground lead around the pipe has worked for me before. If coiling one direction does not seem to help, try the other direction.

    I've torch cut some pipe that had some kind of sulfur build up on the inside. It would attack your lungs. Organic mask would be called for.

    Other than the sulfur or rust build up on the inside, I don't recall any trouble torch cutting drill stem.

    Your Weldpak has a 20% duty cycle. I found that to be a big problem when I tried to do some production welding.

    So your choices are some AC7018 (which I like), a bigger MIG or a surplus of patience.

    I'm not the patient kind.

    I had heard that drill stem was cast steel, but that doesn't make sense for what it is and how it's used, not much information on it, what I found indicates it is a carbon steel alloy 4130 or 4330 or similar alloy.

    Alot of the Texas Fence builders use stick everyday and they are doing thousands of miles of this stuff. Pretty sure you'll be ok with the buzz box. If you can't get an extension cord long enough they make generators big enough to run it. I got a 6.8kw rigid that runs my stickmate. I wouldn't go much smaller than that on the DC side. Ac it uses less power. How much less I don't know.
