Introduction: There is no electricity for the generator. Sometimes the diode plate for welding is also related. If the diode plate is removed, there is a possibility that the diode plate is broken or the diode plate and other lines are short-circuited. Gasoline-powered electric welding machine A power-generating electric welding dual-purpose machine is a good helper for standby power welding machines for outdoor works, outdoor repairs, outdoor railings, and road repairs. There are many reasons why Rennes gas-fired generators are used for welding generators. We conduct a one-on-one investigation. First, we check that there is no electricity in the welding. If the welding has electricity, then there is no problem with the motor. Only the AC line goes out. Check along the line. .
Side Sealing Flat bags are made from Food Grade Virgin material. environmentally friendly and hygienic. They are water-proof, Moisture-proof, strong toughness, tear resistance, good for storage and usually for packing sugar, biscuits, candy, coffee bin, fruits , drinks or other foods. Normally width from 3 inch to 12 inch. Length from 7 inch to 22 inch. Material could be in HDPE or LDPE.

If there is no electricity in the welding, there is a problem with the motor. Check the motor as follows: Disconnect the electric citizen if the hood starts:
1. Remove the carbon brush first and check if it is damaged. If it is damaged, replace it with a new one.
2. Check if AVR is bad, if it is damaged, replace it with a new one
3. If there is no problem with the carbon brush and AVR, start the machine to take a universal table to hang the 750V gear to measure whether the two lines of the 220V motor have electricity (if there is more than tens of volts, then replace the million meters. The open position of the motor shall be disconnected between the motor outlet and the terminal of the AVR. Use the energy meter to measure (sampling line) (sub-line) and whether the main line can pass; if it can pass, the generator stator should not be broken;
4. Check the rotor and the rotor with a universal meter. Check if the copper is bad. If it can pass, check whether the magnetic polarity of the rotor is positive or negative.
5. The generator does not have electricity Sometimes the diode plate of the call welding is also related. If the diode plate is removed and there is electricity, it may be that the diode plate is broken or the diode plate and other lines are short-circuited.
6. Check if the motor has worn out and if the motor has burned out. If it is burned out, replace the motor.
