Red Seal Welding Practice Exam

What is the coolant to water ratio for a specific operation?

1. 120:1

2. 25:1

3. 50:1

4. 10:1

The correct answer is: 25:1

The coolant to water ratio for a specific operation varies depending on the type of operation and the materials being used. A ratio of 1201 (option A) is too high and can result in poor heat transfer and inefficient cooling. A ratio of 50:1 (option C) is also not ideal as it can lead to mineral deposits and corrosion. A ratio of 10:1 (option D) is too low and can result in overheating and damage to the equipment. Option B, with a ratio of 25:1, is the most recommended as it provides adequate cooling and prevents any potential issues from arising. It is important to consult the manufacturer's guidelines or a professional to determine the specific coolant to water ratio for a particular operation.
