 3. Welding position. The first performance characteristic to consider. High cellulose coatings, like IngersolleandAirCompressorStartUpKitModel20103420 those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld IngersolleandAirCompressorStartUpKitModel20103420 metal good for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 IngersolleandAirCompressorStartUpKitModel20103420 and E6013--that hold out-of-position weld metal in place as it solidifies.4. Welding current. Covered electrodes run on AC, DC, or both. When welding DC, the positive lead typically connects to the electrode (DCEP, or reverse polarity). Some suppliers design electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with the available current. High-deposition electrodes. These contain iron-powder additions in the coating to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, IngersolleandAirCompressorStartUpKitModel20103420 use the largest diameter possible for an application-the thicker the electrode, the greater its current-carrying capacity and the higher the deposition rate. Welding out of position and overhead, select a small diameter electrode to enable welders to reach into narrow root openings.Gas-Metal-Arc Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous feeding IngersolleandAirCompressorStartUpKitModel20103420 to the gun; IngersolleandAirCompressorStartUpKitModel20103420 diameter, 0.030 to 1/16 IngersolleandAirCompressorStartUpKitModel20103420 in. typically, although wires as small as 0.020 in. and as large as 1/8 in. are sometimes used. AWS lists specifications for filler wires of copper and its alloys, aluminum and its alloys, surfacing alloys, nickel and its alloys, IngersolleandAirCompressorStartUpKitModel20103420 titanium and its alloys, carbon and low alloy steels, magnesium alloys, and zirconium and its alloys.
