I got this for a job welding on hot dipped galvanized steel and haven't used it since 2020, so it's time to sell it to someone who can use it. Here is a link to Lincoln's website with the specs: https://www.lincolnelectric.com/en/products/k3930-1
This will come with extra batteries, filters...
I own and use a lot of large stuff. On sockets I have up to 2-1/2" and on wrenches I have the same. On metric I have up to 36mm on both. I also have 1" and 3/4" drive stuff to include impacts and torque wrenches.
I sold tools in the industrial market for years and we even had such good pricing I sold on Amazon as well. I even helped a guy on here one time with a return for Wright Tool. You'll notice I said that in the past tense. Tools are a cut throat market. My company did over $5million in tool...
I collect them and there probably won't be enough. I stash them all over as I always find myself needing one and I don't want to head out to the garage to get one.
I'd go for a Makita as well. I sold power tools for years and the circular saws we never got back for warranty issues were Makitas. Of the guys that wanted high quality tools they always chose those saws as well.
I use Dixon Air Chief couplers made by Dixon. They are pricey but work great and are made in the USA.
