Good post,IMO, telling someone that they should be running such and such rod at XXX amps or that running at certain amps is too cold or too hot is nonsense. Every machine I have ever used (and that is a lot), the dial is never the same but close enough to start with. One machine might run 1/8" 7018 at 95 amps on the dial while someone elses might be set a 150 and both weld the same. For instance, my Miller runs 3/32 7018 fine at 75 amps and is perfect for 1/8" at about 105 although I can run much hotter if I want. You have to set the machine so it burns the rod correctly. You should be able to start the rod without excessive sticking (rods will stick occassionally even if it is 50 amps too hot to weld with), rods should burn in sufficient for good penetration and properly fuse all edges without cold lap or undercut. If it is too high amperage, you may see undercut, excessive buckshot and even the rod melting out of the holder prior to getting more than 2/3 of the rod used. My advice is that when someone says set your machine at so and so amps, just take that with a grain of salt as your machine might be way off from that. For newbies to welding, that may be a good starting point but dont expect to have to keep it there if you cant make the weld look good. You will you learn where the controls on the machine weld best with a little practice, that is what the dial is for, adjust it to get best performance. With a properly set machine, you should be able to weld without full dress leather gear to keep the sparks off.
Just a "tack"......:laughing: That gets me every time.Thanks, I dont weld in tee shirts due to burning by the UV light, but as far as sparks, I could do that. I blistered my neck a couple days ago welding in a low neck polyester blend shirt. I was just going to do a little tacking but turned into about 3 hours of welding. I should go back to wearing my neckerchief when welding like I did when I worked as a welder. I still have a white spot on my neck that the pigments are burned out of from excess UV rays before I found the bandana like the old cowboys wore.
By the way, I got one burn on my shirt from some hot slag when it popped of the weld. I usually do more clothing damage with the grinder sparks than welding.

Over the years people I know that wanted things welded would always say something like "it's just a 2 minute weld job". If there is such a thing I've never seen one.
Polyester + Welding = Not Fun.
Sounds like a plan to me... I've always said, "Let's get one of everything first, then worry about what we'll do with the extras".

A lot cheaper that wayThat and I feel like the only person on here without a tractor.![]()

I just need $500 for a down payment. And I would rather spend $500 as a down payment on a tractor, then $350 on a welder. Plus it will be fun to rebuild the kubota.
Those are great little tractors. My B7100 has surprised me with how capable it is. Let us know what you end up with
I will. It will probably have to wait until summer, so I can get some work to pay for it. Oh well, just another drawback of being in high school.
