I haven't had this welder but just a few weeks and am getting really frustrated, when it arrived at my door the front bezel was broken. Then I go to hook up the torch and it is plumbed up wrong so I was not getting any gas. Now my high freq isn't working. So far this thing might have been cheaper than the big brands, but I wouldn't be working on one of them all the time, so I guess the savings isn't that great. I have tried several times today to get ahold of tech and nobody called me back.
