 Duty-Cycle RatingPower-supply rating depends ColemanPowermagePortable10 and GallonAirTank on the type and thickness of the workpiece and the length of time it takes to deposit ModelC10 the longest ColemanPowermagePortable10 weld on the thickest GallonAirTank material. Duty cycle is the key factor to consider when selecting a power source. Once the engineer has determined the current and voltage needed to accomplish the ModelC10 weld, he then reviews duty cycle requirements.Duty cycle rating is the percentage of time during a 10-minute period a power supply can operate at rated output amperage ColemanPowermagePortable10 without overheating. A 300 A machine at 60-percent-duty cycle can weld for six minutes at 300. A during a 10-minute period. Alter six minutes, the welder must GallonAirTank rest the machine for the next four minutes to avoid overheating the unit. High-deposition electrodes. These ModelC10 contain ColemanPowermagePortable10 and GallonAirTank iron-powder additions in the coating to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the thicker ModelC10 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 ColemanPowermagePortable10 uses solid wire, spooled or reeled, for continuous GallonAirTank feeding to the gun; diameter, 0.030 to 1/16 in. typically, although ModelC10 wires as small ColemanPowermagePortable10 as 0.020 in. and as large as 1/8 GallonAirTank in. ModelC10 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 ColemanPowermagePortable10 alloys. Mix GallonAirTank 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 ModelC10 proportions.Fluxes classify as basic, acid, or neutral. Fluxes that contain oxides and break up easily during welding are basic. These provide oxidizing action and alloy with the weld metal to obtain desired ColemanPowermagePortable10 mechanical GallonAirTank properties. ModelC10 Acidic oxides break up slightly, for the same reasons. Welding voltage must remain within the ColemanPowermagePortable10 range specified by the manufacturer of acidic and basic fluxes. Excessive arc voltage reduces the alloying of flux constituents with the weld GallonAirTank 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 a particle size produces unstable art''s and uneven weldbead ModelC10 edges.
