Hello 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 . Thanks Phil Lohiser W8KLK
