    So I got a welder finally sooo happy. I need some help, I got the dryer plug from Lowes today (the welder just came with exposed wires, and I will by using the 230 outlet for our dryer to power it) so I have the plug and everything taken care of I just need to make an extension cord now. I need about 25 feet and I am pretty sure I can use this stuff at Lowes, I think it’s called like service wire,? It’s good for 300 volt etc...(It meets specifications for the welder) it should work for an extension cord right? So my plan is to wire the plug (which has a 6 ft cord with little "O" connectors already on the end, 3 of them) to the wires on the service cord (its power cord not communication cord or anything like that) then the other end of the service cord to the exposed welder wires (about 3 feet of wire coming out the back of the welder). So my question is how do I go about connecting all these wires together???i am assuming the simple "twist" method wont work with this kind of voltage.

    P.s. it’s a 230 volt welder working at 25 amps the outlet is 230 volts at 30 amps.
    Also the plugs wires don’t have markings on them or anything for ground and power??? So does it just not matter where I hook up each wire??

    EDIT: also the wires on the plug and this service cord are both 10/3 gauge

    What's the gauge of the "service" wire?

    White is your common
    Black is your hot
    Red is your hot
    Green is ground

    Personally, I would hook the "service" wire directly to the welder (remove the 3' it has already) and the plug and eliminate all of the connections all together.

    ok but how would i go about hooking up the other connections from the plug to the service wire?? i like the "O" connector things. could i just stick a bolt through them (if i added more connectors to the service wire) and clamp them down? then wrap in electrical tape, and add a little tubing around them???

    gauge on the service wire is 10/3 just like the plug.

    Then what you got is for 110V. You need what you have, but with 4 conductors like 98T said.

    its a china welder....i just checked white is hot and black is hot and green is ground. so i guess 110 white (doesnt say volts on it, just 110) and hot black (doesnt say volts on it, just 110) make 220 volts and then green being the ground. does that all sound right?
