Since posting the initial question, I really appreciate the dfiscussion which has followed. However, not being a welder, I do not understand the reasons for the discussions between the inverter and transformer based units. I'm sure each has advantages and disadvantages. Since a welder I'm not, but I know the inverter and transaformer discusions are about how the electricity gets "made into" an arc which does the melting. Could someone please explain more about the two methods and why they are important to TIG welding?
My welding experiences consisted of a class at the community college where the instructor, who was a very old curmudgeon, gave us steel plates and we stick welded on them for weeks. No theory or machine opertions, just weld the plates. We got to look at a TIG and MIG machine but couldn't use. I think the instructor didn't know how to use them!
Being ROAD KILL on the Information Super Highway and Electrically Challenged really SUCKS!!
Every problem can be solved through the proper application of explosives, duct tape, teflon, WD-40, or any combo of the aforementioned items.
