The DF-601A protects electronic components such as ABS, engine management systems, fuel injection systems, radios, alarms and other sensitive electronics. Achieve greater protection by increasing voltage surge protection during mig and spot welding, jump starts, plasma cutting, and other repair applications.

Our unit out performs the rest and gives you greater protection features such as a heavy-duty varistor, not a small diode insuring maximum protection and peace-of-mind. Dent Fix manufactures this product proudly in the USA and we are so confident in the superiority of this product we offer a lifetime warranty.

A red LED indicates that the device is working and correctly connected. If the unit is overloaded or damaged, the light will go out.
