Hi all. I am a newbee here. First time. I have a Lincoln SP 175 Plus mig welder and the other day when I was feeding the wire through I noticed the wire getting red hot in the welder just before the feed wheel. I made a new welding table and had the welder mounted to a metal frame on the table. I thought the welder might be grounding out so I took it out and put it on the floor. I welded with it for a couple of hours and I noticed it happening again. Any thoughts on that? Thanks.
