I got an incredible deal on a CIGweld 200A AC/DC Tig Welder!
If you look at Blackwoods, they might have a couple left ($1100 for a full kit ready to weld)
After getting all the things you need to do TIG, a pedal is the most expensive add-on.
For some reason they are in the hundreds of dollars range. Not any more!
Once I have this prototype done.. I might make a kit for it.
