Shop tip: check drive-roll tension, liner condition, and contact-tip size before replacing the whole gun. Many feed problems start with setup or a wear item.
The most useful nearby paths, kept short for fast scanning.
A contact tip guides the MIG wire and carries welding current into the wire. If it wears, burns back, or does not match the wire size, feeding and arc stability can get worse fast.
