Hi again everyone I own a castomag 150 mig which is a very old but very good welder unfortunately it has not been used more than once in the last 12 months and I went to use it yesterday and it has developed a fault the wire is not stuck as I can pull it through with pliers but it is not feeding through so I would welcome any suggestions on how to bring it back to life when the gun trigger is pulled you hear one loud click as normal but no wire feed the gas is feeding many thanks Chris
