 Mix recovered flux before reusing to maintain its manufactured properties. Three-parts new flux mixed with one-part recovered flux works well. Consult the flux manufacturer for proper proportions.Fluxes classify as basic, acid, or neutral. Fluxes that contain oxides akrtanks and break up easily during welding are basic. These provide oxidizing action and alloy with the weld metal to obtain desired mechanical properties. Acidic oxides break up slightly, for the same reasons. Welding voltage must remain within the range specified by the manufacturer of acidic and basic fluxes. Excessive arc voltage reduces the alloying akrtanks of flux constituents with the weld metal. Neutral fluxes do not oxidize alloying elements or add alloying elements to the weld. As amperages increase, flux particle size should decrease. Excessive current for akrtanks a particle size produces unstable art''s and uneven weldbead edges. Power SuppliesWelding power supplies take alternating or direct current from a power line or portable generator and convert it to current usable at the welding arc:, Check National Electrical Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction and performance requirements of individual machines.Among types of power supplies, alternating-current (ac) transformers are least costly-most use 230 V single phase input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- akrtanks or three-phase power to produce constant voltage akrtanks (cv) or variable akrtanks voltage (vv). AC-DC transformer-rectifiers can AC and DC weld. 3. Welding position. The first performance characteristic to consider. High akrtanks cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of akrtanks the weld metal good for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 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.
