What Voltage Stabilizer Is Used For Factory Welding?

Factory welding does not require any voltage stabilizer. Welding machines are currently adapted to voltage fluctuations of 10% to 15% based on the rated voltage. This voltage fluctuation range is normal and the welding machine can work normally.
There are two situations in which the welding machine causes insufficient voltage: insufficient capacity input; the cable is too thin﹨too long﹨or both.
1: Insufficient capacity. The welding machine is an inductive load, and the arc is in a short-circuit state at the moment of arc initiation. The input current requirement at this time is 1.5 to 2 times that of the full load of the welding machine, so sufficient capacity is required to ensure the normal operation of the welding machine. Otherwise, insufficient capacity will cause the welding machine to operate normally without load, and the voltage will drop suddenly after the arc is ignited and it will not work.
2: Cable problem. The input line length should not exceed 5 meters, and the input line of some AC welding machines should not exceed 3 meters. Cables that are too long will cause voltage drops. The input voltage of the welding machine is insufficient. The cable is too long, the wire diameter is too thin, or both will cause the welding machine to fail to operate due to insufficient input voltage.
For the above two reasons, the problem can only be solved by increasing the capacity of the transformer; or increasing the wire diameter and shortening the cable length. Instead of using a voltage stabilizer.

The cost of buying a transformer is more expensive than Dynamic Voltage Regulator (DVR). It would be strange if your equipment is not burned when the voltage is cut to a high level! A dynamic voltage stabilizer only costs 8,000 to 9,000 yuan.
