I have an old brazing kit bought years ago [about 30 years] and never used for years either. The system was the Ergo which comprised of a torch ,oxygen bottle and small bottles of Malgas. The malgas has never been available for years ,but I was wondering if I can use a suitable alternative gas with the oxygen. I dont even know if I can get the oxy bottle filled [ rules & regs] . The torch and pipes are in good condition and just wondered if I can bring this little kit back to life. Any advice would be apreciated.
