Hello to everyone, just joined this great forum, so be gentle to a newbee. I have the above mentioned welder. My problem is the tension roller does not run true, i.e. when the roller is feeding the wire, it wobbles from side to side thus causing the wire to coil up and stop it from feeding the gun. At this time, i cannot get replacement parts for this machine. Does anyone know where I can get one that is compatible with this welder ? Many thanks to all. Regards, Frank B.
