In order to achieve an optimum spray pattern, which adjustments should be made on the spray gun?

To achieve an optimum spray pattern with a spray gun, it is essential to make adjustments to both the fluid adjustment and the fan width adjustments. The fluid adjustment controls the amount of material being delivered through the spray gun, ensuring that the correct volume of paint is applied. This is crucial because too much or too little fluid can lead to issues such as drips, streaking, or insufficient coverage.

On the other hand, the fan width adjustment influences the shape and width of the spray pattern. A proper fan width helps in maximizing coverage while minimizing overspray and waste of material. Together, these adjustments allow the painter to fine-tune the application for different surfaces and types of paint, ensuring an even and professional finish.

While adjusting air pressure and fluid tip/nozzle size can also impact the overall performance of the gun and the quality of the paint application, focusing specifically on the fluid adjustment and fan width provides a more direct and immediate means of achieving the desired spray pattern. This combination is fundamental for achieving an effective and controlled painting process.
