wires # 202 and # 203 going to plug # J3 on the main P.C. board.
4. Splice the black wire extending from the Control to wire # 202 and
the white wire to # 203.
5. Adjust the "VOLTAGE" control as necessary and ignore the "WIRE
FEED" knob on the Wirematic front panel.
notes: 1. Proper operation of the PA-G1 kit is dependant upon the correct input voltage value.
2. The feeder inside this unit will also be turned ON, so disengage the spring tension on the
drive roll.

The PA-G1 Control (P/N 005-0264) can also be connected to the SP255 as follows:
1. Remove the hinged lid and right side panel of the SP255.
2. Locate Plug J3 on the main PC Board (lower center). Find the red wires # 202 (goes to plug J3
- pin 1) and # 203 (goes to J3 - pin 3).
3. Splice the black wire extending from the Control to the red wire # 202 and the white wire to the
red wire # 203.
4. Locate trigger lead plug J13. It is a connector plug coming through the center divider of SP255.
It can be found just forward of the upper left side of the main PC Board. There'll be a 6-Pin plug
and just below it a 4-Pin plug. The 4-Pin plug is J13. Splice the red to wire #325 PIN #2 and the
green to wire #324 PIN #4.
5. Replace the right side panel and hinged lid.
6. The easiest way to mount the PA-G1 Control is on the side of the unit and to bring the wires from
the Control through the louvres on the front of the unit.
7. Adjust the "VOLTAGE" control as necessary and ignore the "WIRE FEED" knob on the Wirematic
front panel.

The Wirematic 250 and Wirematic 255 are interfaced using the WC-1 Weld Control or the Cobramatic
Cabinet as follows:
1. Connect the black and white contactor leads from the WC-1 or Cobramatic
to the two solid pins on the 4-Pin Amp plug (trigger plug). Place the
contactor in the CLOSING CONTACTS position (see Appendix for contactor
information).
2. Plug the 115VAC plug from the unit into a standard wall outlet.
3. Tape off WC-1 red and green leads and turn off Posa Start switch as Posa
Start is not used.
4. Adjust the "VOLTAGE" knob as needed and ignore the "WIRE FEED" knob.
