Tweco® Heavy Duty Contact Tip accommodates 5/64" 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 0.09" 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.

Nice Versatile and Strong Cart
Material Type: Three Tiers Cart
The cart looks great and fits our needs perfectly. It is very sturdy and well made. However, it took a lot longer to put together than I expected because there many parts and they have to fit together perfectly. Worth it though!

Not for someone that needs step by step instructions and pre-drilled holes
Nice cart that looks good once assembled. But be warned: there are NO predrilled holes for any of the screws. You will need to build each section of the frame that attaches to each wood panel FIRST, sit it on the wood and use a electric drill or driver to put the screws into the wood.
Same goes for the wheel attachments - no holes drilled for these either.
So if you are someone that can't even build a piece of IKEA furniture - this is NOT for you as this will require more skill and power tools.

Great Cart, Difficult Assembly
Material Type: Three Tiers Cart
This cart is beautiful and met our expectations. We read many reviews good and bad, so we knew what we were buying. The cart was packaged and delivered perfectly. It is very heavy so help may be needed. It took 4 hours to put together, there were no predrilled holes and some of the metal poles need to be adjusted slightly to fit correctly. The instructions were straightforward, drilling holes prior is very helpful. The wood was a darker brown and I actually liked the imperfections of the knots giving it character. Overall, I would buy this cart again. It is very pretty and will look amazing in our camp.
