the tip will make the welds cleaner. Get that new wire in there tomorrow and have at it.
Speaking of welding... our welder has been acting erratic to the point where we stopped what we were doing to have a look at it and half the ground wires were gone so it must have been zapping the amps. So we fixed that first and still couldn't figure out why the welder was acting funky. Then someone looked closely at the tank and it was 100% argon.
I welded a huge slice 18G and just figured the welder that I thought was already acting inconsistent was now getting progressively worse. So the guy after me who welded 22G REALLY noticed it.
