What is a Tweco contact tip?

i have a Lincoln SP135T MIG welder. It came with a .025" wire and contact tip set up. I am looking for some .025 and .030 tips but the OEM Lincoln brand are hard to find. I do see Tweco "style" tips even from Lincoln. What is Tweco, a brand or a style? And can I use those tips with my 100L gun?

Yes, that is a style of tip, and also what your Lincoln uses.
