    What are you welding? 

    How THICK is it? 

    Your welder has electrodes? 

    Should only have a single electrode. 

    Rough guide: 

    ¼" = .250" electrode = 250 amps 

    ⅛" = .125" electrode = 125 amps 

    Do you see the pattern? 

    Your metal better be more than 1/2" thick if you're using a 1/4" electrode and all that current. 

    P.S.  I looked at your welder specs.  It's only 225 amps AC, so a 1/4" electrode is already at the maximum size for your welder wide open. 

    Please explain what you plan on welding.

    Then you don't need to be operating it - and please tell me you aren't welding anything important.

    1/4" electrodes?  250 amps  1/4=250

    . usually 1/8" electrodes or  125 amps 1/8=125 unless you are building the Titanic II
