Question: 1 / 400

To prevent burn back into the torch when cutting thin materials, you should:

Lower the gas pressure

Increase the cutting speed

Use a smaller tip

One should use a smaller tip to prevent burn back into the torch when cutting thin materials. This is because using a smaller tip will result in a smaller and more focused flame, reducing the likelihood of the flame going back into the torch. The other options, which include lowering the gas pressure, increasing the cutting speed, and turning the torch up, may not be as effective in preventing burn back and could potentially lead to uneven cuts or damage to the torch.
