What is the difference between an acetylene nozzle and a propane nozzle

First, the appearance is not necessarily the same: acetylene cutting nozzle has a ring and plum blossom type; Propane nozzle is usually plum blossom type.

Second, the outlet is not necessarily the same: the fast air outlet of the propane cutting nozzle is generally indented a little; The outlet of the acetylene cutting nozzle is generally a little more protruding than the fast outlet of the propane cutting nozzle.

Third, the alternative is not the same: generally propane can also replace acetylene, that is, the temperature of propane is lower than the temperature of acetylene, preheating and cutting slower, the cutting effect is the same; The substitution of acetylene for propane may cause insufficient temperature to affect the cutting effect.
