When users need to use multi- hole socket to expand the use of electrical equipment, the power line and socket connected to the equipment should be ensured that both of connected two power lines are not less than 2.5 mm² and that the connecting lines and sockets are free from skin damage, and ensure that the connecting lines and sockets are dry. Pay attention to safety!
9. The AC120V/240V inverter of this device adopts overload automatic protection. When the power of the electrical appliances exceeds the maximum output power of the device, the device will stop AC120V/240V output. When the power of the electrical appliances is lower than the maximum output power of the device, the device will automatically recover.
10. This device is equipped with a built-in fan for forced air cooling, which is intelligently controlled. When the internal temperature of the device reaches a certain level, the fan will automatically start. When the temperature of the device drops to a certain level, the fan will automatically stop. When using this device, ensure that the front air outlet and rear air inlet are unobstructed to prevent metal foreign objects from entering the device through the air outlet and causing equipment damage.
11. The welding machine circuit of this device is protected from overheating during use. Please ensure to rest for 5 minutes when the machine is turned on. After the internal cooling of the machine is restored, it can be used. Please pay attention to shielding the battery equipment under direct sunlight to avoid overheating and equipment protection.

Equipment Storage
Storage requirements

1. Power station, battery and charger should be placed in a cool and dry environment after use. If the device, battery and charger are not used for a long time, put the device, battery and charger back to their original packaging and store them in a dry environment.
2. When the battery is not in use, the best storage temperature is 25±5°C, and it can also be placed in a cool and dry environment.
3. After the battery is used, it should be charged in time. It can’t be stored for a long time if the battery is not fully charged. If the battery is not used for more than 3 months, the battery needs to be fully charged. If the battery is not used for 6 months, it is better to do one battery charging and discharging cycle. Regularly charging and discharging the battery can ensure the activity of the battery and prolong the life of the battery.

Equipment Maintenance

Welding problems and solutions

The phenomena listed here may be related to the accessories you are using, welding materials, environmental factors, and power supply conditions. Please try to improve the environment to avoid such situations.

A. It is difficult to start an arc, and it is easy to break the arc:

1. Make sure that the quality of the electrode you are using is good, and the electrode with poor quality may not meet the requirements for high-quality welding;
2. Electrodes that have not been processed by drying treatment are also not easy to start arc and will bring arc instability, increase welding defects, and deteriorate welding quality. 3 A longer cable will cause the output voltage to drop too much. It is recommended that you shorten the cable length as much as possible.

B. The output current cannot reach the rated value:

1. The deviation of the battery voltage from the rated value will make the output current value become inconsistent with the set value; when the battery voltage is lower than the rated value, the maximum output current of the welding machine may also be lower than the rated value.

C. The current cannot stay stable during the use of the welding machine. This situation may be related to the following factors:

1. The battery voltage changes
2. The welding output cable is entangled

D. Too much splash:

1. The current may be adjusted to too large, and the diameter of the electrode is too small;
2. The positive and the negative of welding machine output parts is connected reversedly. Under the normal process, a positive polarity welding is used, that is, the electrode is connected to the negative polarity and the workpiece is connected to the positive. Please interchange the positive and negative polarity.

Equipment Maintenance

1. The inverter(power station) has no AC 120V/240V output:
   • A: Inverter overload protection: Whether the power of the electrical appliances exceeds the rated power of the inverter(power station); When the electrical appliances are inductive load with big power motors, their starting power is greater than the instantaneous output power of the inverter(power station).
   • B: Whether the battery voltage is too low: Please check the battery level indicator light and check whether the inverter’s abnormal indicator light is on or not;
   • C: Inverter overheating protection: Please check whether the fan inside of the inverter(power station) works or not; Please check whether the air inlet and outlet of the power station are blocked or not.
2. The voltage of the electrical appliances connected to the power station(that is, the voltage of the appliances powered by this power station) is too low: Please check whether the AC120V/240V output socket and the electrical plug of appliances are connected too loosely or have poor connection; Please check whether the wire diameter of the expanded patch board used for connecting more appliances is too thin, resulting in an excessive voltage drop;

Charger Problems and Solutions

1. The charger indicator light flashes or keeps on, and cannot enter the charging state:
   • A: Please check if the charger’s charging output port and the battery charging port are connected too loosely or have poor connection;
   • B: Please check if the internal wires of the charger’s charging output cord are aging or broken;
2. The charger indicator light is not on:
   • A: Please check if the charger AC input port and socket is connected too loosely or have a poor connection;
   • Please check if the internal wires of the charger AC input cord are aging or broken;

Battery Problems and Solutions

1. The battery cannot discharge:
   • A: Check if the discharge port is loose or has poor contact;
   • B: Check if there are any debris at the discharge port;
   • C: Check if the discharge port contacts are black, oxidized, and have poor conductivity;
   • D: Check the battery’s various working data through Bluetooth on your phone to see if the discharge port is closed.
2. The battery cannot be charged:
   • A: Check if the charging port is loose or has poor contact;
   • B: Check if there are any debris at the charging port;
   • C: Check if the charging port contacts are black, oxidized, and have poor conductivity;
   • D: Check if the battery is damaged due to long-term feeding.
   • E: Check the battery’s various working data through Bluetooth on your phone to see if the discharge port is closed.
