I don't know if this is the right place but I wanted to help anyone looking for a good welding supplier in the North West, Lancashire area. I'm in Preston and I have been dealing with an excellent place called Preston Welding Supplies.
50 Essex St, Preston PR1 1QE
He has sorted me out with a number of things but he recently swapped out my CO2 X sized cylinder for an Argo Co2 mix and a new regulator.
He was genuinely interested in my project, more than happy to be asked questions by a complete amateur and offered some reallt good helpful advise. Very friendly helpful chap.
