V. Operation & Maintenance Instructions

5.1 Startup Operation/Startup Procedure

1. Check that the welder is secured securely before use/transport to prevent collision damage./Before use or transportation, check that the welding machine is securely fastened to prevent collision damage.
2. Turn on the run switch to start the battery — the battery level display illuminates./Turn on the operation switch to activate the battery — the display screen will light up.
3. Close the main brake to supply power to the components — the fan rotates and the voltage is displayed normally./Close the main circuit breaker to supply power to all components — the cooling fan will start spinning and the voltage display will show normal readings.

5.2 Operation Procedure

1. Select the desired function mode and current parameters — voltage/ammeter display corresponding values./Select the desired welding function mode and current parameters — the voltage/current display will show the corresponding values.
2. Turn off the auxiliary power circuit breaker to supply power to the output socket — auxiliary electric display 220V./Close the auxiliary power circuit breaker to supply power to the output socket — the auxiliary power display will show 220V.
3. The cause of the alarm sound needs to be promptly investigated — the “DiDiDi” beep sound indicates a fault./If an alarm sounds, promptly investigate and resolve the cause-audible “beep” sound indicates a fault.

5.3 Downtime/Shutdown Procedure

1. Disconnect the main gate to cut off the power supply — fan stop, no voltage display./Disconnect the main circuit breaker to cut off power supply — the fan stops and voltage display turns off.
2. Turn off the running switch to stop the output — the display is off./Turn off the operation switch to stop all output — the display screen goes dark.

5.4 Charging Operation/Charging Procedure

1. Check that the wiring is secure before charging, then turn on the charger switch — each indicator light is on./Before charging, check that all connections are secure, then turn on the charger switch — indicator lights will illuminate.
2. Choose a fast charge (30a) or slow charge (15a) mode as needed./Select fast charge (30a) or slow charge (15a) mode as needed.
3. Turn off the charger after it is fully charged, and then unplug it — the indicator light is off./After full charge, turn off the charger first, then disconnect the plug-indicator lights will turn off.

5.5 Precautions/Maintenance Notes

1. Regularly disassemble the machine to remove ash and tighten the wiring terminals./Periodically disassemble the casing for cleaning and tighten all terminal connections.
2. Turn off the operation switch in time after use in winter to prevent power consumption./After winter use, turn off the operation switch to prevent battery drain.
3. Do not disassemble or collide with the lithium battery pack./Do not disassemble, puncture, or impact the lithium battery pack.
4. For long-term storage, keep full power and turn off the switch, and recharge every 3 to 6 months./For long-term storage, keep the battery fully charged with the switch off, and recharge every 3 to 6 months.
