The V350-Pro can be paralleled in CC mode. 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 400 amp procedure, each machine should be set to deliver approximately 200 amps, not 300 amps from one and 100 amps from the other. This will minimize nuisance shutdown con- ditions. In general, more than two machines in paral- lel will not be effective due to the voltage requirements of procedures in that power range.

To set machine outputs, start with output control pots and arc control pots in identical positions. Use the output control pots to balance the currents and main- tain the desired current. The arc control pots should be kept identical on the two machines.
