hi all, could someone tell me what basic tests i could carry out to establish the fault that my automig 180 mono has developed? i was welding a large piece of steel on no 6 and a fast wire feed and the mig blew the 13 amp fuse in the plug. i put a new fuse in and it still wont work. i have checked power supply at first point in unit thats ok. the small fuse inside the mig is ok. now i am stuck. any suggesions would be greatly appreciated. regards, stanman
