Care should be taken to keep the welding machine clean. Compressed air can be used to clean the dust inside, wipe the dirt outside with a cloth. .
Brush on commutator pressure should be appropriate, daily maintenance, such as brush wear too much, to be replaced in time.
As a result of moisture immersion will reduce the insulation resistance of the welding machine. .
The maintenance of three-phase asynchronous motor in DC welding machine is exactly the same as that of three-phase asynchronous motor.
