The welding machine must cool off for 5 minutes out of 10.
Explicación
## Step 1The duty cycle of a welding machine is the percentage of time that the machine can operate continuously without overheating. In this case, the welding machine has a 50% duty cycle, which means it can operate for 50% of the time and then needs to cool off for the remaining time.## Step 2To find out how long the machine needs to cool off, we need to calculate the remaining time. Since the machine operates for 50% of the time, it needs to cool off for the remaining 50% of the time.## Step 3Given that the total time is 10 minutes, the machine operates for 5 minutes (50% of 10) and then needs to cool off for the remaining 5 minutes.
