  • yeah at least now i know what the number in the electrode means

  • christ these videos are garbage. wet 7018 will cause porosity but the main reason to keep them warm and dry is to prevent underbead cracking from the hydrogen contained in water. also ALL rod should be keep sealed from the atmosphere. side note: proper angles 90degree work angle/15degree travel angle more if running vertical up.

    kids, if you want to learn how to weld get some good old books, and few pounds of rod and a good lincoln dc machine and do it.

see all

  • @TurbulentG hey assface, what the hell did i do? it would be awesome if you could form proper sentences. "wtf is a 45 degree angle tilted 30 degrees to the right and you drag the electrode" you obviously don't know what the work angle or the travel angle are, and since you are trying to be a wiseass i'm not gonna tell ya.
