What type of tips available for propane create a hot, concentrated flame?

Swirl jet tips are designed to create a hot, concentrated flame by utilizing a swirling motion that mixes fuel and air effectively. This design ensures that the propane burns more efficiently, leading to a hotter flame. The aerodynamic shape of these tips promotes a vortex, which increases the turbulence of the gas and air mixture, enhancing combustion. This results in a flame that is not only hotter but also more powerful and focused, making swirl jet tips particularly suitable for tasks that require intense heat, such as cutting or welding.

Other types of tips, while useful for different applications, do not create a flame as concentrated as that produced by swirl jet tips. Standard tips provide a more straightforward flame, air-fuel tips can vary the mixture for different burn characteristics, and mixing tips primarily focus on improving the overall mixture of propane and air but may not provide the same intensity of heat as the swirl jet design.
