B-4 B-4 OPERATION PARALLEL OPERATION The Invertec’s are operable in parallel. For best results, the currents of each machine should be rea- sonably well shared. As an example, with two machines set up in parallel for a 300 amp procedure, each machine should be set to deliver approximately 150 amps, not 200 amps from one and 100 amps from the other. This will minimize nuisance feedback conditions. In general, more than two machines in par- allel will not be effective due to the voltage require- m
