Excellent semi-automatic work - first of all. Both in classic and flux. There is a 2-year warranty, which is a good number. I have had it for a little less than a year, but there were no breakdowns. If straight arms are attached to it, then even, strong seams are guaranteed. I cook MMA less often, but everything seems to be ok too. Teague has not yet been needed, I can’t say anything here.
