APPENDIX B
Electrical and Data Connections
Section I. Electrical Connection
As described in
Chapter 2 , you need to supply a connector for the Power Supply input power cable (see
diagram below).
Connect the Power Supply power cable to a 3-phase, 50/60 Hz power source. The voltage range for each
model is set at the factory by a set of two jumper plugs. One jumper plug is installed on power connector
J23, located on the center chassis plate. The other jumper plug, P22, plugs into welding transformer cable
connector J22. The jumper plug set determines the power wiring configuration between the power board
and the welding transformer.

CAUTIONS:
•
Be sure that the shop source power is appropriate for your Power Supply model.
•
If the blue phase wire is not connected, no alarm will occur and the weld control will produce
more than 20% ripple in the weld output waveform.
