Tweco® Heavy Duty Contact Tip accommodates 0.052" wire and is perfect for use with 200 - 400 A Tweco® No.2, No.3 and No.4 MIG guns as well as specific MIG gun series. Contact tip with excellent electrical properties is ideal for use in heavy duty welding application up to 400 A. It features part number and wire diameter for easy identification. 1.47" Contact tip with 1/4"-28 UNF-2A thread size has 0.064" nominal ID and 0.283" OD. 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.

Very good product
Color: Cool Grey, Size: 3 Panel-72''Wide
The material on this soundproof room dividers is really solid. The panels are super thick and do a decent job at cutting down noise. Now, if you're looking to completely soundproof a space, just getting these three pieces probably won't cut it. You'd need to wrap your whole house in them to get that total sound blockage.
The wheels are awesome. They roll super smoothly and quietly, making it a breeze to move this room divider around. The design is really user-friendly and practical.
This sound proof dividers are super handy. It works great in bedrooms, living rooms, offices - pretty much anywhere you need to divide up space and create a quieter environment.
The customer service team is top-notch. When I had questions about the product, they got back to me right away and helped solve my issues. They're really professional and clearly care about making customers happy.
All in all, I'm really happy with this soundproof partition. It's made with quality materials, the wheels make it easy to move, it's super versatile, and the customer service is excellent. I'd definitely recommend it to anyone in the market for a room divider.

Good Room Divider
Color: Cool Grey, Size: 3 Panel-72''Wide
I purchased these for a classroom to provide a sound divider between classrooms. The wheels make it easy to move when necessary. It also works well as a bulletin board.
