        My Lotos CT520D wire feed stutters on 0.035-inch wire at 21V, 260 ipm, liner and tip seems fine. Any solutions?

          Wire feed issues is from bad tension. Check drive roll alignment, adjust tension to 3-4 to stabilize feed.

            Worn contact tip causes stuttering. Replace it, lower wire speed to 240 ipm, my CT520D stopped stuttering. Clean liner with alcohol, check spool hub for tangles, try 230 ipm for stable feed.

              Lower wire speed to 230 ipm, it is gonna help feed smoothly.

                Check drive roll tension, it is probably off.

                  Clean liner with alcohol, check spool for burrs to prevent stuttering.
