Look into hoses and regulators for propane, they can be different
Nope, Victor sells different tips to go on the same torch. The rest of the rig is interchangeable. If the salesman tells you that your acetylene regulator or hoses will not work on propane......he is simply trying to screw you out of the price of new regulator and hoses.
Propane gives you one additional benefit. You do not have to worry about propane detonating if the regulator gets set too high. That red mark on the acetylene gauge is there for a reason.
