    can anyone tell me why i get this brown dicolouration around the welds and some brown in the weld?
    could it be the gas? im BOC argosheild light could i be pushing the limits of the gas shielding capability?
    or could it be bad wire?

    It's nothing to worry about, it comes from the welding fume.

  4. As has been said its nowt to worry about, although, if the welds in the photo are typical of the stuff you do you may want to consider swapping to Universal. The higher CO2 content will give you better fusion etc
