TRANSFORMER SPECIFICATION NOTES:
1
For the Model X11/4/460A, turns ratios
(TR) are selectable by a switch on the
transformer rear panel.
2
HF2 Weld Control Input voltage selection
must be jumpered at E12 on the HF2 Weld
PCB as shown in Figure 2-3. E12 is
located at the center of the PCB left edge.
3
Maximum weld time at Maximum Short
Circuit Current is 50 milliseconds.
