This shows beads formed on amperage settings ranging from too low (cold) to too high (hot) should help, but here are some other things to look for: Slag pockets: black, nonmetallic deposits in the weld. Try keeping the electrode movement steady . . . and hold the rod at an angle closer to perpendicular. Undercutting: a shallow groove along one or both sides of a weld. This usually results from moving the electrode too fast. Slow down a little. Spatter: droplets of metal around the weld. It isn't a serious problem, but-if adjusting amperage doesn't cure it-you may be holding the electrode too high.
