The moisture can get into the flux due to a poor joint seal in the wire manufacturing process, the wire. Sometimes going down only 1/2 volt fixes. As voltage increases, the arc length gets longer. Web what are the possible cause's. If you slow down a little, and allow more time for the gases to evacuate the molten puddle and the. Ime, they are caused by wet flux in the wire, but i have seen guys. If you have and don't know w. If arc length is too long, excessive levels of. Elongated holes are referred to as “wormholes.”. A slight change in voltage or stickout usually will cure it.
Web worm tracks are caused by the gases escaping from the molten puddle, and the puddle (or flux cover) solidifying before the holes can fill back in. Their presence indicates that a large amount of gas has been formed which is then. They occur when gases fail to. Web any idea what's causing the tracks? Especially in case of flux cored wires, if those are folded type instead of seamless bad storage. A slight change in voltage or stickout usually will cure it. Web worm tracks are really just a surface indication, they don't go past the bottom of the track. Web if worm tracking does occur, reduce your voltage by increments of one half volt until you eliminate the problem. Web worm tracks are caused by the gases escaping from the molten puddle, and the puddle (or flux cover) solidifying before the holes can fill back in. As voltage increases, the arc length gets longer. Ime, they are caused by wet flux in the wire, but i have seen guys.
