What is the order that the parts are connected to the torch, starting from the piece closest to the handle?

The correct arrangement of components connected to the torch, starting from the piece closest to the handle, is indeed accurately represented in the chosen option. The O-ring is the first part in the sequence, as it forms a seal and is crucial for preventing gas leaks in the system. Next is the swirl ring, which helps to create a swirling motion in the plasma gas; this motion optimizes the arc stability and improves cutting performance. Following the swirl ring is the standard electrode, which provides the electrical energy needed to create the plasma arc. The standard nozzle then focuses and constricts the plasma flow to enhance cutting precision. The retaining cup secures these components in place, and the drag shield further protects the torch and operator from potential hazards.

This sequence reflects the logical assembly needed for effective plasma arc cutting, facilitating proper function and performance.
