control circuit's closed-loop control makes the power source enjoy strong ability against
power grid fluctuation and perfect welding performance. The schematic diagram is as

1-4 Duty cycle
Duty cycle is percentage of 10 minutes that a machine can weld at rated load without
overheating. If overheats, thermostat(s) will open, output stops. Wait for fifteen minutes
for the machine to cool down. Reduce amperage or duty cycle before welding.
Note!
Exceeding duty cycle can damage the machine and greatly reduce its
lifespan.
