  • Page 11: Parallel Operations

    INSTALLATION PARALLEL OPERATION The EX350i are operable in parallel in CC mode. For best results, the currents of each machine should be reasonably well shared. As an example, with two machines set up in parallel for a 400 amp procedure, each machine should be set to deliver approximately 200 amps, not 300 amps from one and 100 amps from the other.
