Miller HE002076 allows you to adjust the amperage output from the input circuitry in 50-ampere increments from 50 to 350 amperes. It is also protected from damage due to excessive overload by a 400-ampere fuse connected in the input circuitry. With it, you can also function as a welding control station remotely located from the main power source. It provides a receptacle to which the electrode cable is to be connected and also a coarse and fine current control.
