My Lorch 150 inverter went pop ! A couple of days ago , so got it picked up by firm who sold it to me , was purchased in May 2013 but only used maybe 4 times a back up set ! And was like new as the rep said when he picked it up , the thing is I don't think I was sent out the extended warranty ? Got a missed call from rep today left voice male wants to see paper work for warranty wasn't sent any ! Glad I didn't order the tig set 220 I was wanting will see how this pans out before I get another lorch !
