<p>Jplovell: </p> <hr /> <div>Surface mix torch: A torch in which the gases mix after exiting the face of the torch, as opposed to a premix torch in which the gases mix in a chamber. Surface mix torches provide more complete combustion of the gases than a pre-mix torch, which allows for a better flame atmosphere. The atmosphere of a surface mix flame is more suitable for use with most colored glasses than a pre-mix torch. Surface mix torches do not require a flashback arrestor or check valves like pre-mix torches do.</div>

<p>Jplovell: </p> <hr /> <div>Pre mix torch: A torch in which the oxidizing and fuel gases are mixed in a chamber prior to exiting the face of the torch and undergoing combustion. These types of torches are commonly used in welding. Pre-mix torches must have flashback arrestors, and or check valves to prevent the ignited gases from traveling back to the tanks.</div>
