I just got my new 211 with the Spoolmate 100. Man am I happy with this machine. However on my very first weld with the spoolgun I toasted the tip All the way into the barrel. After reading all day it is apparent that I'm not the only one that has had this issue. After ordering another barrel assembly ($45) I discovered an article about how to drill out and retap the barrel so the normal mig gun tips will work in the spoolgun. If this is a known problem then why hasn't Miller dealt with it. It sounds like the tapered tips are the problem due to over heating. Any ideas or the modification or suggestion on how to keep this from happening. I'm kinda gun shy because of the cost to keep replacing barrels or tips. Seems to be a common issue. Thanks for the advice. TW
