In a scenario where multiple torches are used on a large fitting, what position should the secondary torch be at?

The proper positioning of the secondary torch when working on a large fitting is crucial for effective heat distribution and the successful completion of the soldering or brazing process. By placing the secondary torch at the 5 o'clock position, heat is directed towards the area that requires solder or braze, while maintaining control over the heating process. This position allows better access to the joint, ensuring that both the primary torch and the secondary torch can work in synergy to evenly heat the entire fitting and joint area.

In soldering and brazing, even heat distribution is essential to prevent stress and potential damage to the materials being joined. The 5 o'clock position strategically facilitates this, providing a natural flow of heat that circulates around the joint. This approach helps in avoiding overheating any single area, which can lead to warping or burning of the metals involved.

Thus, using the secondary torch at the 5 o'clock position effectively supports optimal heating strategies, ensuring a strong and reliable connection between the components.
