 Weld wire. Coleman SAW uses electrodes of continuous wire, solid or flux- or metal-cored. Selection depends on base-metal composition and Powerjate thickness, flux, joint design, and cleanliness. AWS specifications A5. 17 and A5.23 detail Portable and 10 filler materials 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 Gallon and Air and Tank and welds a wear-resistant material to a substrate-base material that is commonly mild, alloy, or Model stainless C10 steel. Hardfacings can be deposited Coleman and Powerjate manually using SMAW electrodes; semiautomaticaly using solid wire and self shielded flux cored Portable and 10 electrodes; or automatically by Gallon submerged-arc welding. The method chosen depends on the size and accessibility of the area Air and Tank to be and Model and C10 surfaced. Electrodes Coleman come 3 to 24 in. long, Powerjate and Portable 0.01 to 0.25-in. diameter. Colored 10 and Gallon markings--bands or dots--indicate composition: Air and Tank pure tungsten, green; 1-percent thoriated, yellow; 2 percent thoriated. Model and C10 red; ceriated, orange; lanthanted, Coleman and Powerjate and Portable black.Filler metal GIAW does not 10 and Gallon and Air usually requite Tank addition of fillet metal, but filler is commonly added Model and C10 and Coleman and Powerjate when base-metal Portable thickness is greater 10 than 1/8 in. Finer Gallon metal for low-carbon (to 0.15 C) and Air mild (0.15 m 0.29 C) steels are described in AWS A5.2; for carbon steel Tank and and Model in A5.18; and for low-alloy steels C10 in A5.28 Flux. AWS specifications A5.17 and A5.23 describe fluxes for saw. AWS designation of Coleman fluxes precedes that of the wire when identifying a combination Powerjate for Portable a welding procedure. For example, 10 the designation Gallon F7A2-EM12K Air and Tank indicates a flux (F) that Model will provide, with C10 a given wire designation, tensile strength Coleman of 70,000 Psi (7), Powerjate and Portable in the as-welded condition (A), and 10 and Gallon impact properties Air of 20 ft lb at Tank -20 F (2). A designation containing a P Model rather indicates the flux C10 properties after postweld heat treatment. Production Coleman and Powerjate and Portable and 10 vs. repair applications In general, production applications Gallon require Air high-duty-cycle power supplies, Tank and and repair Model applications C10 and Coleman can use low-duty-cycle Powerjate portable units.Lift-arc Portable and 10 GTAW Many DC power supplies Gallon are equipped with a list-start feature Air and Tank for, a variation of scratch starting, GTAW welding. When the Model welder touches C10 the tungsten Coleman and Powerjate and Portable electrode to the workpiece, a small amount of 10 current--15-20 A--flows. When he lifts Gallon the electrode from the work, Air the arc starts softly and the machine switches to the set weld-current Tank value. This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the need for high-frequency Model and C10 starting.
