I bought one of these, and I like it, although not nearly as much as my MillerMatic 200.
I have lately run into problems when I want to run something at the top of the parameters of the machine. I went and asked for an .045 liner, and they gave me the wrong kind, an .035". The machine has rollers for .030, so don't know if it would even run .045. I did get a roll of .035" FCAW.
I turn up the heat, and the wire speed, but I just can't seem to get the puddle and fusion I need. I'm welding on some 1/4". The trigger situation has been solved by the addition of a $2 doorbell bar, but the speed or something seems intermittent. I haven't really done a ton of welding with it on lower settings with .025" or .030", but can't get that sound I like with the higher settings.
Maybe I need to get out the FCAW, or just stick weld thicker things?
Anyone have any thoughts of a 175 at the top of the range?
Heart surgery pending?
