Flux core wire?

dartfreak75 a couple of tips:1) If it has slag you drag as a rule of thumb. 2) If welding vertical and the material is less than 1/4" than you can run downhill, 1/4" and thicker you should run uphill with a slight push travel angle, when I say slight, pointing the gun straight in is 90 degrees you want about a 80 degrees gun nozzle up using a slight Z pattern pausing ever so slightly on the toe lines to allow undercut to fill in. 3) When welding in the flat or horizontal position drag the gun with a slight C/crescent moon movement, this is assuming you are right handed if you are left handed than it would be a backwards C. 4) clean after every pass or anytime you stop before putting another bead on top of the slag, if not cleaned it causes slag entrapment which can cause the weld to fail.
Hope this helps and good luck. If you have any questions I'm more than happy to try and help.
