    Building projects made from water well pipe and oil pipe

    I have some projects to build. I like really strong, really cheap building materials.
    At the local agricultural auction I can the get water or oil pipe I would use for around $1 per foot.
    I have just never worked with it before.
    I will probably pickup a pipe notcher for these projects.
    Also have air compressors and all the grinders and stuff you would normally expect for removing thick scaly rust.

    The 2 main uses would be building utility style solar panel mounts on the ground and fence repair.

    For the solar panel mounts I will have utility power available, since it's going to be a grid tie install I kind of have to have power out there. I have my 185 amp Lincoln made AC buzz box, the miller model 250 if I can drag it out there, my very mobile home made 100 amp DC only alternator welder.

    Then typical fence repair.
    For most of the fence repair I will only be able to get my home made 100 amp DC alternator welder out there for most of it.
    The alt welder runs all 3/32 inch electrodes very well.

    If 100 amps isn't enough to do pipe my ACdelco made DR44G alternator welder could make around 200 amps with a bigger engine.
    If 100 amps isn't enough I can replace the 5.5hp Honda engine with an 8 to 13 hp engine. An 8hp engine could give me 130 to 140 amps and a 13hp engine could give around 180 to 200 amps.
    Is 100 amps enough to weld up fencing from pipe?

    I was planning on using 6013, 7014 and/or 7018, all common sizes then maybe break out some left over 5/32 inch lincoln 10018 if i can get big blue out there.
    I have heard of electrodes made specifically for welding rusty old oil pipe together for fencing but have no idea what they are called.

    What is the preferred AC electrode for pipe welding pipe?
    DC electrode for fence building when limited to 100 amps?
    DC electrode for nearly unlimited high quality dc power you get from a miller model 250?

    These are some solar panels I welded up from my neighbor, it was all built with recycled pipe and square tubing he scrounged up. He did the engineering, I did all the welding with my Lincoln HD 180 using 75/25.

    thats a nice looking solar set up, do the panels move at all to follow the sun?

    While limited to 100 amps, 1/8" 6010 or 6011 would do a good job on used material with minimal prep.

    Re: Building projects made from water well pipe and oil pipe

    I agree with Dave. 6011 is real good to burn through rust though I'm not saying no cleanup is OK. 6010 is OK but it requires a little more OCV to start the arc.

    Re: Building projects made from water well pipe and oil pipe

    The miller mod 250 has good starting ocv.
    My home made alt welder does about 86 to 88 volts DC open current at full speed. I actually have not tried 6010 on it yet.

    That panel setup is very nice.
    They don't appear to be on trackers.

    Re: Building projects made from water well pipe and oil pipe

    How would something like a miller 211 running nr-211 powered by 240v handle the above stated pipe?
    I have been thinking about getting one.

    He designed it to follow the sun.
    There is an indexing sector that allows him to tilt the panels in four stops.
    He adjusts them according to what time of year it is.

    I’ve never seen a Miller 211. Here is .045" NR-212 run with a 1966 engine drive welder.

    I think you'd be very pleased running nr-211 through a Millermatic 211. Even the cheapie weldingcity gassless flux core wire that I ran through mine welded up great. But I would advise a higher amperage gun as the stock M100 gun can get toasty quick. I have a 15' HTP M25 gun for it (250A) if you need one.

    NR-211 in 0.030'' and 0.035'' is often used in 180 amp and smaller machines.

    Re: Building projects made from water well pipe and oil pipe

    If using stick 6010 +p works okay even if rusty. running wire even fluxcore it has to be a lot cleaner or you will get porosity
    There are several tracing templates that you can buy and just run the torch around. one is shur cut The odd angles just print off an online template cut it out and trace it. i dont know if they make a mechanical notcher that can do oil tube it would be a beast

    Re: Building projects made from water well pipe and oil pipe

    I was thinking I would get a pipe holder setup for a drill press and just notch the 90 degree joints.

    The notches can be quickly cut with a chop saw at an angle. The angled cut makes the rounded throat.

    Using a template and plasma is also very fast - even easier than chop saw.

    Finish with a round rock in your angle grinder and you're all set

    Re: Building projects made from water well pipe and oil pipe

    With 100A on tap, I would think that would be enough, especially if you were to run 6010 or 6011 on DC. Lincoln 6010 5P+ in 3/32" size only need about 60A to light-up on 1/8" material. I think in 1/8" diameter, 5P+ only need about 80A IIRC. What is the wall thickness of the pipe?

    Re: Building projects made from water well pipe and oil pipe

    The pipe thickness appears to be nearly 1/4 inch.
    If I was using thin pipe like near emt conduit thickness I would just use my 120v mig.

    Can your alternator welder light up 6010s? If so, I don't see why you wouldn't be able to run 1/8" 5P+ to dig in nice and hot. Unless the voltage is too low to light them up(?)

    Re: Building projects made from water well pipe and oil pipe

    I have never tried to run any 6010 on the alt welder, I'm going to have to try it.
    The alternator welder builds up to about 86 volts at no load.
    This isn't just a car alternator, it's been heavily modified.

    No worries if it won't - 6011 will run good and have similar performance.
