The copper strike strip is to not contaminate the tungsten with any foreign particles, such as steel, which will stick to it, copper wont, so its a good way to start the arc without HF start....
Also, watch ebay for the high frequency units. I bought a miller HF-1-WG unit that does HF and water/gas too for $230, works great, beefy old unit (still grey, not blue like the newer stuff). Still working on getting a welding trailer together around my lincoln ranger (kubota power baby) so I can be a lot more organized and mobile...
check weldingdepot.com, they have a lot of deals there, also might want to post a WTB request at shopfloortalk.com forums.
