    So, that is the gas line at the power lug.

    If it has connections for gas then maybe that's the only way to run it.

    I'd try the stickout from tip to work like we had mentioned. If that's not it and polarity can't be changed and you were ok with fluxcore then maybe rent a 5# CO2 tank for low cost to test the machine before you jump all in with 75/25.

    Re: Mig will start an arc but has almost no heat

    Got some CO2 gas and wire, this is the best I could do...didn’t get the frying bacon sound more of a rapid popping like a machine gun. I played a bit with the heat and wire speed

    See if you can find the model number printed on the welder case.
    It will be near where the welder specs are printed.
    I am guessing it will be 117-001 through 006. If so your welder is MIG only.
    Positive on the wire and must use gas.
    Model number will start with 117-.
    You can go to Lincoln electric's web site. Pick the support tab then find parts.
    Then guest. enter the model number in the code number box. wait for a selection to show up and select it.

    if your welder is a 100 amp welder it will not weld .035 mig wire.
    use only .030 or .024

    it is a 117-003 welder. I got gas .030 wire, and tips. It is better but not right.....figured out the potentiometer for the wire feed is all over the place. 70 inches per minute to 580 in one step up on the dial. Locating the part now....bet it runs right when the wire speed is correct!

    New pot should help. Lets hope it is not the control pcb.
    Just for kicks, clip you dc meter to the drive housing and the other clip the the contact tip. run out about 2 inches of wire. trigger welder read the voltage drop across the miggun. a good gun will read less than 1 volt. a bad gun will read over 15 volts. gun is pulled apart and weld conductor is open, only the liner is carrying current. Unfortunately there is nothing helpful on the Lincoln web site.
    Try calling 1-866-236-0044 this is tech support for century products, new and old.
    They should be able to e-mail you manuals for your machine.
    might have it on my old computer but it started a virus scan and can't use it until it is done several hours from now.

    Definitely need to work on CTWD. That's what, about 2.5 inches?




    Sorry Legacy, you need to watch some good beginner videos on MIG/flux core welding, preferably from Weldint Tips & Tricks on Ebay. Very reliable source.

    If it was set for solid wire mig with gas and you are using it with flux core, the polarity is wrong.

    It's usually a matter of bolting and unbolting wires inside the spool panel.

    Download the manual, read it twice
