Tweco® 11 Series Heavy Duty Contact Tip accommodates 3/64" wire and is perfect for use with 160 - 250 A Tweco® No.1 MIG gun as well as specific MIG gun series. Contact tip with excellent electrical properties is ideal for use in heavy-duty welding application up to 200 A. It features part number and wire diameter for easy identification. Contact tip is made from extruded or gun-drilled 122 DHP copper alloy and machined from a copper alloy tubing to offer a consistent as well as smooth surface of inside diameter with +/-0.003" tolerance. It has threaded style that ensures proper contact with a gas diffuser when installed to the MIG gun. It comes in slip-on or thread-on nozzle styles with a choice of diameter bore sizes. Contact tip locks in place when twisted and offers better electrical conductivity with increased surface contact. Contact tip features thick-walled design that acts like a heat sink conducting heat away from the arc source. It can be twisted quarter turn clockwise when tip wear point is reached that reveals a new wear point for doubling the life of the tip. Contact tip is sold as 25 per pack.

So nice but not a good fit on my foot
I love these boots so much, they’re exactly what I wanted. Unfortunately, they are too big in the heel and flop, while too tight in the toe. I know the toe would stretch with wear, but can’t deal with a floppy heel, they pulled my socks down off my feet. I do have narrow feet. Too bad, I’m so disappointed! They seem well made and would go with everything. Comfortable, too, if they fit right.

Cozy, Stylish, and Perfect for Everyday Wear

I absolutely love this oversized knit sweater! The material feels soft and comfortable against the skin, and it keeps me warm without feeling heavy. The oversized fit is flattering and easy to style with jeans or leggings, making it perfect for casual outings or relaxing at home. The stitching looks well-made, and after washing, it still holds its shape nicely. Great quality for the price — I’d definitely recommend it!
