Compatible Lincoln MIG Guns
These tapered contact tips fit Lincoln Electric Magnum 200, Magnum 250L, Magnum 300 and Magnum 400 series guns. They also suit the LE31MP series and numerous K-series models such as K1722-2, K1802-1 and K2286-1. The pack contains ten standard-duty tips for regular wire-fed welding tasks.
Buyers needing other wire sizes
Welders who run wire larger than 0.03 in. cannot use these tips. The standard-duty rating also means they are not intended for continuous high-amperage applications that demand heavy-duty consumables. Shops using non-Lincoln gun brands should verify thread and tip geometry before ordering.
Maximum wire diameter 0.03 in.
This single limit decides whether the tip matches your welding wire. Only wire measuring 0.03 in. or smaller feeds correctly through the tapered bore. Always confirm your wire size against this figure before purchasing.

Questions about this item
How do I install the tapered contact tip on a Magnum 250L gun and what step is often missed?
Thread the tip into the diffuser until it seats firmly; the step often missed is confirming the gun model — K471-2 or K471-4 — matches the compatible series list before installation.
What replacement schedule should I expect for these standard-duty tips when running 0.03 in. wire?
Replace the tip when the bore shows visible wear or the taper edge degrades; lifespan varies with amperage and wire feed speed, so inspect each spool change.
At what amperage does a standard-duty tapered tip reach its thermal limit on a Magnum 300?
Standard-duty tips are rated for the Magnum 300 series; the practical limit appears when the tip overheats and wire feed becomes inconsistent, typically near the gun’s 300 A rating.
