Greetings All,
I checked the dropbox to see if the tif was there and it is. Once
again look for two files that begin with SP125. There is a tif of the
schematic that can be read clearly if blown up and a text file
explaining the circuit changes and operation of the added purge
button. If you make these changes be sure to coat the board and added
components with some type of conformal coating to prevent shorts from
the conductive dust that blows through the welder.
