Anyone own one of these? If I set my wire feed speed around 80-90 IPM, when I press the trigger, a small amount of wire comes out and then stops. I have to release the trigger and then press it again for more wire. I would think that wire feed would be continuous but at a slow speed. Anyone else have this issue? Is it normal behavior for this welder? Mine did the exact same thing but as I welded with it over the next couple months it started coming out continuously working like it was supposed to. Just recently let it set for 2 months and hooked it up yesterday to use it and it won't work at all now.. biggest POS ever
