I recently purchased a used oxy/acetylene torch set with owner tanks, G350 regulators, and a Victor WH370FC-V w/ CA370V cutting head. It does not have a rosebud/heating nozzle, which I want to purchase. My Acetylene tank is 145 cf. 1/7 of the 145 cf is 20.7 cf per hour withdrawal rate limit. Victor shows a min. of 6 cf and max of 20 cf for the #4 rosebud, and a min of 14 cf and max of 40 cf for the #6 rosebud. I'm assuming I'm limited to the #4 rosebud with my tank size, or should I be able to use a #6? Not sure if I can go by the min cf, or if I'm limited by the max cf?
2nd question: The existing hoses are looking a little sketch, with burn marks, etc. I'm going to purchase some new "T" rated hoses. Is the 1/4" big enough to run a #4 or #6 rosebud, or should a person step up to 3/8"? I'd prefer to find a made in the USA hose, but does any specific brand of hose stand out as the one to get?
