    Default Worm tracks

    I am getting worm tracks please help 28 v 230 amps 25 pressure ,using .052" dual shield .
    adjusted amps "tweeked" still getting them this is while dragging ,
    if I push it works better.

    Thanks

    Years ago in a welding shop we would get worm tracks if the stickout wasn't long enough. The explanation was something about moisture in the flux and the longer stickout gave more time to preheat it. I am not so sure of the credibility of that explanation but it did work to go longer. You can easily go 1 inch or more on stickout with dual shield.
    Cheers,

    What are you welding? Plate or Pipe? What position.

    In my experience, wormtracking is most often caused by using too high a voltage for the set wire feed speed(amperage). As a previous poster said, it can also be caused by moisture in the wire. Correct stickout is a factor in this. But wire that's set out too long in a very humid environment can develop wormtracking issues. So can welding on wet steel.

    What specific product are you welding? What wire feed speed are you using?

    If by pressure, you mean gas flow rate, 25 sounds a little low, unless you're using 100% CO2 gas.

    You should be using a drag or straight in angle for flux cored wire; unless you're welding vertical up. Then a slight push angle is OK.

    1) incorrect voltage..check wire weld parameters for stick-out etc.
    2) gas coverage.. we run our flowmeters up around 40 cfh inside the shop
    3) base metal contamination
    4) dirty / rusty wire
    5) avoid drafts

    I had issues a year ago in my shop when I started teaching. We went to straight co2. But bigger thing was not enough gas. 40-50 cfh is what weld parameters said. As suggested look up consumables data sheet will give u a start point for all settings including gas flow, voltage & wire feed
