Ok let's get this straight, I purchased a almost new Victor portable cutting torch rig with bottles and everything. Only problem I have is filling those pricy little tanks up. I read that a propane Oxygen torch will do almost as good. IT should work for me since max I cut is 1/4". I have a bunch of those tall blue bottles for propane toches, I like to hook up them up. The fittings are not the same as acetylene bottles. What type of fitting do I need or adapter?
