Hi im Pete, I first visited this site, because I was searching for tech. data on the Wolf 140X mig that l purchased during the lockdown. My interest is in aluminium welding, so l also purchsed a, cheap, spool torch head. The conversations regarding the live tip were very interesting. I had anticipated that l would need to modify the machine which is why l went for the cheapest. If l can achieve my aim l will happily share any info. I gained from the conversations that the live tip head is an issue. I have also, just now, orderd two 200A starter relays (less than £7 each) that l hope will allow me to switch between the spool head and the standard one. If l don't meet my demise in this process l will be happy to offer the wiring diagrams.
