Ok, so im new to welding but i do know the basics. I recently aquired a brand new Lincoln flux core welder and tried it for the first time yesterday. When i went to start welding, the wire would feed but no arc. I was using a clean piece of metal and it was grounded good. Then, without changing anything, i was able to get an intermittent arc. The wire would continue to come out, but would only arc about once every half a second or so. I figured it was probably the wire i was using, which was the wire that came with the welder, so i tried some other wire but it did the same thing. Pretty confused about the whole deal cause there isnt much adjustment on the welder itself. I also tried basically every wire speed setting and its still not working right. Any advice?
