 Power SuppliesWelding ColemanPowermatePortable10 and GzllonAirTank power supplies take alternating or direct current from a power line or portable ModelC10 generator and convert it to current usable at the welding arc:, Check National ColemanPowermatePortable10 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, GzllonAirTank alternating-current (ac) transformers are least costly-most use 230 V single phase input power. Direct-current ModelC10 (DC) transformer-rectifiers convert ColemanPowermatePortable10 AC to DC, using single- or three-phase power to produce constant voltage (cv) or variable voltage (vv). AC-DC GzllonAirTank transformer-rectifiers can AC and DC weld. 3. Welding position. The first performance ModelC10 characteristic to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal ColemanPowermatePortable10 good GzllonAirTank for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 and E6013--that hold out-of-position weld metal in ModelC10 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 ColemanPowermatePortable10 electrode negative GzllonAirTank (DCEN, or straight polarity). Assure the electrode will perform with the available current. 5. Joint design and material thickness. Some electrodes create an arc that penetrates deeply, performing well on thick sections with narrow ModelC10 grooves or no bevel. Poor fit-up ColemanPowermatePortable10 calls for electrodes that can bridge wide gaps.6. Efficiency. GzllonAirTank Meeting all other ModelC10 conditions, engineers select the electrode that gives highest deposition rate. For heavy-section joints, use powder-metal-addition fillers.Designating electrodes for carbon and low-alloy steels, following the prefix E'', to signify a SMAW electrode, come two or three digits to indicate minimum tensile strength in 1,000 PSI units; a digit indicating ColemanPowermatePortable10 usable current and electrode-coating type; and, in some cases, a hyphen followed by a GzllonAirTank letter and number suffix to denote weld metal composition. Example: E7010-A1 is a SMAW electrode (E), ModelC10 of ColemanPowermatePortable10 70,000-psi tensile strength (70), for use in all welding positions GzllonAirTank (1), having a high-cellulose-sodium coating tin ModelC10 use with DCEP (0). -A1 ColemanPowermatePortable10 indicates a particular composition listed in the A5 specification. A-1 suffix, as in 7018-1, indicates high impact toughness at a temperature lower than specified GzllonAirTank for a standard E7018 ModelC10 electrode.
