thanks for all the suggestions guy's, to be honest i agree about using pure argon, i know you get a much better weld with it but i have been using argon mix ever sinse i started this car and it's only recently it's started to be a pain in the preverbial. it could be down to the electrodes, i'm not sure if there are any shite quality tig electrodes out there, i'm guessing there are... i will inspect the coupler at the machine, it's a quick release type but i know i get gas out at the torch end, i can hear and feel it, after that it'll be another torch lead, gas bottle, machine lol
