P3-P4 Shorting Plug Kit - P/N 37514
These jumper plugs must be plugged into Migmaster 251s Main Control PC Board Assembly, P/N 38111, when
options are not installed. Operating the Migmaster 251 without jumper plug or option connected to P3 and P4
receptacles of the PC board can damage the circuitry. Therefore, connect the small 6-pin jumper plug to P4 of the
PC board if preflow/postflow option is not installed; connect the large 12-pin jumper plug to P3 if spool gun control
option is not installed.
NOTE: The same P/N 38111 PC board is used in the 251cv Power Source. The jumper plugs are
not required for
this unit.
