Note: Based on the generator rating, age, and condition, adjust the cutting current as needed.
If a fault occurs while using a generator, turning the power switch quickly to OFF and then to ON again
(sometimes called a “quick reset”) may not clear the fault. Instead, turn OFF the power supply and wait 60 to
70 seconds before turning ON again.
