Product Overview
The M16291-2 is a small-wire replacement liner for Lincoln-style MIG guns. A liner is one of the most common causes of feeding problems when it is worn, kinked, contaminated, too tight for the wire, or mismatched to the wire diameter. Replacing the liner can help restore consistent wire feeding, reduce birdnesting, and reduce erratic starts when the rest of the MIG gun and drive system are in good condition.
Because MIG gun liners are fitment-sensitive parts, do not order by wire size alone. The correct liner depends on gun series, lead length, wire diameter, connector style, and cross-reference number. For this product, the key ordering identifiers are M16291-2, 35-40-15, and KP35-40-15.
