Lincoln Copper Plus Contact Tip 550A, Tapered, .052 in (1.3 mm) 100/pack KP2745-052T-B100

Q: What wire size is the Lincoln Copper Plus Contact Tip 550A, Tapered, .052 in (1.3 mm) 100/pack KP2745-052T-B100 designed for?

The Lincoln Copper Plus Contact Tip 550A, Tapered, .052 in (1.3 mm) 100/pack KP2745-052T-B100 is sized for .052 in wire. The contact tip bore must match the wire diameter — a bore that is too tight causes friction and erratic feeding; a bore that is too loose reduces electrical contact quality and increases arc wander. Always verify the contact tip diameter matches your wire spool before welding.

Q: Which MIG gun is the Lincoln Copper Plus Contact Tip 550A, Tapered, .052 in (1.3 mm) 100/pack KP2745-052T-B100 compatible with?

The Lincoln Copper Plus Contact Tip 550A, Tapered, .052 in (1.3 mm) 100/pack KP2745-052T-B100 is designed for use with Lincoln Electric Magnum series MIG guns. Verify the thread size (M6 or M8) and thread pitch match your specific Magnum gun model before ordering. Contact tips are not universally interchangeable between gun brands even when labeled for the same wire size.
