If the damage of electrode thread and end face exceed the regulated requirement, please contact with after sale service members to confirm whether it can be used.
2. Check where the socket plug is clean before the connection of electrodes, it should be cleaned first if there is impurity. If the electrode is damped by water, it should be dried before using.
