    Default broken cutting edge

    Seems like I've done a few of these lately. I know you guys like to replace but I've had good luck repairing. On a PC200 that is over worked. Just patched up the thumb two weeks ago. Gouged out one side about halfway & welded with 7018. Gouged other side into weld & welded out with 7018.

    I've have good luck using Lincoln NR 311 ni fixing cracks. I use the 5/64 and run it at 29 volts with wire speed of 230 ipm. I've had 7018 fail a couple times but I've never had a failure with the NR 311. Just got to make sure you can get a flat surface. Looks good though

    I always use Triple 7 or Outershield elite wire with co2 gas.....even in the field. So easy to carry a small bottle of co2 and an ln25.......set up a make due shield(masonite works well) and have at it. The only place I find a use for stick nowadays is if my root with wire is porous from dirt/grease or on very small repairs where the time to set up the ln25 isn't justified. Also will use stainless for small cast repairs or stick for stud removal. The dual shield wire with co2 is much more ductile than with the c25 and once it is setup it welds great. Dave

    I think someone asked before but have you ever gouged one of those with oxy/act and a gouge tip?

    I would love to get ahold of a job like that but all I could do is grind it out or oxy/act it out.

    Out is out I guess no matter how you do it.

    Never gouged with oxy/acet as I have always had a cac setup so I couldn't even give you pointers.

    Ive always gouged out any crack on a bucket wity oxy acc and a gouging nozzle
    Makes the job a lot quicker and easier to grind prior to welding
    If in the workshop i would use 1.2 mm wire with argoshield and really high juice, never had ome re break!
    If on side id still gouge out and grind up but root with a 2.5 7018 (i always first arc up on a piece of scrap to dry and warm up th rod) run it in with around 80 amperes and fill and cap with a 4mm 6013 at around 140-150 amps
