for the money that welder great. I have been running a large spool of lincoln. .030 flux core wire. I have welded the floors (ollie my 10 year old did most of it), I have built my bumpers, fabbed a stereo box, and a bunch of othe stuff around the garage. I cant tell you how much of the spool I've gone through because I haven't had to open the access panel up for any reason. It just keeps welding. I have been wanting to get another gas bottle for shielding gas to play with but honestly it welds so well with flux core and I don't mind cleaning the slag off.
I haven't used the spool gun yet.
Hope this helps in your decision. I would recommend the 175. I've been looking at their plasma cutters now.
