1. The procedure tables assume tight fit up and adequate clamping or tacking for fast travel soeeds and minimum distortion Use copper backing whenever possible to decrease burnthrough tendencies When poor fit up is encountered 1 Reduce the current 2 Increase the drag angle 3 With E6010 or E6011 electrodes use a quick whip technique with a slight circular motion in the crater to bridge the gap 4 With E6012 or E6013 electrodes use a small quick weave technique to bridge the gap 18 When welding with High Speed electrodes E6012 and E6013 deposit the entire weld in one pass using non weave beads or a slight weave Drag the electrode on the joint and stay ahead of the molten pool Use enough drag angle so the arc force pushes the weld metal back Use currents in the high portion of the elec trode s range When welding with Out Of Position electrodes E6010 and E6011 deposit the entire weld in one pass using non weave beads or a slight weave Hold a 1 8 or shorter arc Move as fast as possible while maintaining good fusion Use currents in the middle of the electrode s range Weld overhead joints using E6010 or E6011 electrodes with a whip technique and a slight circular motion in the crater Do not weave Point the electrode directly into the joint and slightly for ward into the direction of travel Use a fairly short arc and travel fast enough to avoid spilling Use currents in the lower portion of the electrode
