    Lincoln AC-225-S

    Just purchased this unit used.

    Its not like all the other 225 welders, mine has a flat top, with rounded corners. Like these:

    Do you guys think all the ones made in Canada were flat top?
    Mine has these markings
    Code No, W-190 7
    Type K-1170
    AC-225-S
    CM 9803-1

    States its made in Toronto Canada, but should have a CI not a CM for March 1998.



    Info on the color ranges from Plastikote Fire Red, Safety Red, Fire Truck Red
    to Rustolium Royal Rad, or Regal Red, or Sunrise Red
    Dupont Centari Auto - Powder Paint Red B8902AW
    Sherwin WIlliams J22XXR16517P4337
    Dupont pre 91 is 6334, 91-97 is 45832 and 97+ is B8012


    There is a black wire, label on it states H2, my digital multi meter hooked up to that, goes to the bottom left on switch. Seems to be heat shrunk, with some red paint. Not sure if its suppose to be connected to anything or not. The bottom left has a wire hooked up to it, I cant tell if H2 is the same wire, or connected to another wire. It is all heat shrunk.

    That's the Canadian shape.

    I found a picture of paper tag online about the h2 and h3. It states for the 230V input, connect h3 and fan motor to switch and insulate lead h2. For low line voltage connect h2 to switch and insulate connection of lead h2 & fan motor. Does low line mean 110V, since h2 is insulated?

    Best guess as to the shape other then the "Canadian" model LOL is the age of stick welder. Looked high and low for the serial, dont think CM 9803-1 is it, since CI is Toronto. I have found no stamps anywhere on the metal. The only thing with any numbers is the face plate.

    I’ve seen plenty of units like this, all made in Canada. It’s been awhile since the ac180 amp machine was made. The are all 225’s now. My 1991 250 ideal arc is also a flat top, made in Canada machine.

    I doubt they were referring to 120 volts when they said low voltage. More likely they mean 208 volts like you'd get from 2 legs of 3 phase.

    I was going to get a unit that converted two 120V outlets on different phases, but the input line would only handle 15A or 20A whatever the circuit breaker is rated for on the 120V line. Needless to say I purchased a clamp meter because it was on sale for 80% off. Cleaned her up nice, spark plug cleaner on the contacts, cleared out the cob webs, cleaned up the welding gunk caked onto everything. On the hunt for some diode rectifiers.

    Lots of YT channels to choose from for learning, anyone have a welding YT channel they prefer?

    Thanks for the input.

    Re: Lincoln AC-225-S

    Hey thanks guys.

    I just hooked up the machine for the first time, and did my first sparks, I wont call them welds. I had it at 60A for some 1/4" (no joining steel) and the 6013 would stick, not enough juice. Then moved over to joinery and slowly raised it to 100A when I got my first "bead" what an amazing feeling to melt two pieces of steel together. I have to get the feel for how much feed to give the rod into the puddle. Definitely have to hook up 240 outlets in both garages now, and go on the hunt for scrap steel.

    For a long time I always pondered trying this out, just felt overwhelmed and the cost of the machines through me off. I paid $160 cdn for the box, no cables, no clamps or holder. I bought everything from Power Fisted Princess Auto. Into it all for probably $225'ish.

    I bought their house brand rods PowerWeld, 5lbs, because they were on sale, half off.
