Designed for welding pipe and general structures. Excellent for all-position and vertical down welding. Slag is light and easy to remove. Deep, penetrating arc. Low deposition rates. Polarity DC + (electrode positive).
Similar to E6010 but modified to allow use of AC. Excellent for welding sheet metal corner joints vertical down. Polarity AC or DC + (electrode positive).
Designed for welding sheet metal and light structural steels. Medium penetration suitable for gaps or where minimum weld dilution is needed. Ideal for flat, horizontal, or vertical down welding. Will weld faster than the E6010-11 electrode. Polarity AC or DC—(electrode negative). Excellent AC or DC—performance. All-position. Shallow penetration. Good choice for low open-circuit welding machines. AC or DC both excellent on thin structural applications. Polarity AC or DC (DC both polarities).
Iron powder is added to the flux to provide higher deposition rates. Ideal for multipass groove and fillet welding in flat and horizontal positions. Polarity AC or DC (both polarities).
Table 12 shows approximate current requirements for AWS E60XX electrodes for weld ing sheet metal carbon steels. The current ranges specified vary slightly with different electrode manufacturers. For welding sheet metal start at the low end of the given current requirements with electrodes of 3 ∕ 16 -in (5-mm) diameter or smaller. For metals thicker than 10 gage (0.134 in.), start in the center of the current range, then adjust to suit. A high DC current may result in arc blow, and improved results may then be obtained with AC. Table 12. Diameters of AWS E6010/E6011 SMAW Electrodes for Welding Low-Carbon Steel Sheet Metal SWG of Sheet Metal to be Welded Electrode Diameter Current Starting Level in. (mm) (amps) 18 3 ∕ 32 (2.5) 45–60 16–14 1 ∕ 8 (3.2) 80–110 12 5 ∕ 32 (4) 125–135 10 3 ∕ 16 (5) 135–150 For welding thicker materials, a good starting setting is in the middle of the current range shown in Table 12. In welding material less than 1 ∕ 4 -in. (6.4-mm) thick, vertically, with an E6010 electrode, try a 1 ∕ 8 -in. (3.2-mm) electrode at 90 to 100 amps. For welding thicknesses between 3 ∕ 16 and 5 ∕ 16 in. (5 and 8 mm) with the E6010 electrode, vertically, try the 5 ∕ 16 -in. (8-mm) diameter electrode at 100 to 125 amps. For thicknesses of 3 ∕ 8 to 1 in. (9.5 to 25 mm), try a 3 ∕ 16 -in. (5-mm) diameter electrode at 155 to 165 amps. Recommended current ranges, shown in Table 13 for the various sizes of AWS E60XX electrodes most commonly used for welding carbon steel, will give optimum results with SMAW electrodes. An ideal starting point for the current setting for any SMAW electrode diameter is in the middle of the range. The current ranges shown are average values taken from literature of electrode manufacturers in three different countries.
