Sorry no pics, but I thought I would pass this on. My CWS Mig 160i suddenly started acting weird with the wire burning back to the tip and hesitating mid weld. Sure enough when I ran the wire out in mid air I could see that it would wind out smoothly then pause for a split second then carry on.
Having eliminated all the usual suspects it turned out to be a bit of swarf or similar gouged into the welder's internal wall at the back of the wire reel randomly getting caught on the "spokes" of the reel, just enough to slow the reel and cause problems.
