Question: 1 / 400

Why is a smaller tip used rather than turning a torch down when cutting thin materials?

To increase speed

To improve precision

To prevent burn back into the torch

A smaller tip is used when cutting thin materials because it helps prevent burn back into the torch. This is important because burn back can damage the torch and affect its performance, ultimately costing more money in repairs and replacements. Turning the torch down may seem like a viable option, but it can actually lead to slower cutting and less precision. Additionally, using a smaller tip can also help to reduce gas consumption, making it a more efficient choice. However, the main reason for choosing a smaller tip is to prevent burn back and maintain the longevity of the torch.
