    Am wondering if any of the readers of this group have been following the
    various arc welder mods. that have appeared on different web sites and
    newsgroups , I have seen some interesting work from Igor's shop and a couple
    variations of the Dave Barrett design , all are using high
    power IGBT's and controllers , looks like Igor is using a commercial control
    and the Barrett design is using a homebrew CMOS /TTL , it seems like several
    welders/HAMS are very interested in this subject , if anyone knows of a
    source for actual schematics that are somewhat proven and or PC boards etc.
    , I would appreciate hearing from you , have talked with a number of people
    on the web , all expressed interest , most didn't want to spend an unlimited
    amount of time and money , with no chance of success .
