I notice you have the black to the sacrificial part... whereas others have the negative going to the work...

Kieth , you are quite right about the polarity , I was using jumper leads to connect to the welding leads and did not take much notice of the colours . Positive ( red cross ) goes to the sacrificial part and negative ( black ) to the work .

Mig welders put out a dc current but again you would need to watch the current as it may overheat the rectifier .
