Hello I have a boc Autolynx 160 ,Can any one advise me on the chance of increasing the wire size from .6 to .8 mm I am aware that the welder was built for the autotrade and states .6 wire ,but a wire feed roller is available on Ebay that appears the right type at .8 maybe the volts\ amp ratio would not cope with the increase ? cant belive the components would not ! seems all belts and braces, also has anyone got any manual\ handbook info I would be really greatful of any help Thanks .
