 Weld wire. SAW uses electrodes of continuous wire, solid or flux- CllemanPowermatePortable10 or metal-cored. Selection depends on base-metal composition and thickness, flux, joint design, and cleanliness. AWS specifications A5. 17 and A5.23 detail filler materials GallonAirTank and ModelC10 for SAW of carbon and low-alloy steels; A5.9 and A5.1, filler metals weld corrosion-resisting stainless steels and nickel alloys, respectively.Hardfacing ElectrodesHardfacing welds a wear-resistant material to a substrate-base material that is commonly mild, alloy, or stainless steel. Hardfacings can be deposited manually using SMAW electrodes; semiautomaticaly using solid wire and self shielded flux cored electrodes; or automatically by submerged-arc welding. The method chosen depends on the size and accessibility of the area to be surfaced. Production vs. repair applications In general, production applications require high-duty-cycle CllemanPowermatePortable10 power supplies, and repair applications can use low-duty-cycle portable GallonAirTank units.Lift-arc ModelC10 GTAW Many DC power supplies are equipped with a list-start feature for, a variation of scratch CllemanPowermatePortable10 starting, GTAW welding. When the welder touches the tungsten electrode GallonAirTank to the workpiece, a small amount of current--15-20 A--flows. When he lifts the electrode from the work, the arc starts softly and the machine switches to the set weld-current value. This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the need for high-frequency ModelC10 starting. High-deposition CllemanPowermatePortable10 electrodes. These contain iron-powder additions in the coating to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, GallonAirTank use the largest diameter possible for an application-the thicker the electrode, the greater its current-carrying capacity and the higher the deposition ModelC10 and CllemanPowermatePortable10 rate. Welding out of position and overhead, select a small GallonAirTank 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, ModelC10 for continuous feeding to the gun; diameter, 0.030 to 1/16 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, titanium and its alloys, carbon and low alloy steels, magnesium alloys, and zirconium and its alloys.
