Final answer:
The required temperature for a flameless electrical heat gun when removing lead-based paints in residential housing units varies but is typically between 250-450 degrees Celsius. It is important to follow the manufacturer's instructions and safety guidelines when using an electrical heat gun.
Step-by-step explanation:
When removing lead-based paints in residential housing units, flameless electrical heat guns are commonly used to avoid the risk of fire. The required temperature for these heat guns depends on the type of paint being removed. Lead-based paints typically require temperatures between 250-450 degrees Celsius to soften and facilitate removal. However, it is important to note that the exact temperature required may vary depending on factors such as the thickness of the paint and the specific heat gun being used. It is essential to follow the manufacturer's instructions and safety guidelines when operating an electrical heat gun.
