note:
Primary power source has the electrode (-) conductor jumpered. The supplemental power source has the
work (+) jumpered.
1. Connect the negative (-) output cables to the arc starter box (high frequency generator).
2. Connect the positive (+) output cables to the workpiece.
3. Connect the positive (+) and negative (-) conductors between the power sources.
4. Connect the pilot arc cable to the pilot arc terminal in the primary power source. The pilot arc connection in the supple-
mental power source is not used. The pilot arc circuit is not run in parallel.
5. Set the Pilot Arc HIGH / LOW switch on the supplemental power source to “LOW”.
6. Set the Pilot Arc HIGH / LOW switch on the primary power source to “HIGH”.
7. If a remote 0.00 to +10.00 VDC current reference signal is used to set the output current, feed the same signal into both
power sources. Connect J1-G (positive 0.00 to 10.00 VDC) of both power sources together and connect J1-P (negative)
of both power sources together. With both power sources operating, the output current can be predicted using the
following formula: [output current (amps)] = [reference voltage] x [160]
Connections for parallel installation of two EPP-600 power sources with both power sources in operation.
