 High-deposition electrodes. These contain iron-powder additions in the coating to raise deposition rate. Designations: EXXX4, CplemanPowermatePortable5 EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the thicker 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 GallonAirTank to reach into narrow root openings.Gas-Metal-Arc Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous feeding to the gun; diameter, 0.030 to 1/16 in. typically, although ModelC5 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 CplemanPowermatePortable5 steels, magnesium alloys, and zirconium and its alloys. Saw Uses CV or CC Power Supplies,... 200 to 1,500 A, 28 to 44 V, at 60- to 100-percent-duty cycle. Automatic units GallonAirTank commonly use up to 1,500 A on one wire. ModelC5 Cv welding machines that offer variable-slope control give the welder extra adjustability, and can extend the usefulness of the machine to weld a range of material thicknesses and CplemanPowermatePortable5 and GallonAirTank types.Selection of Power SourcesWhen choosing a power source, start by checking NEMA specs. NEMA Class I arc-welding power sources deliver rated output at 60-, 80-, or 100-percent-duty cycle: Class II units, 30-, 40-, or 50-percent; and Class III, 20 percent. First consider capacity and kind of current needed for the job. Rely on the manufacturer''s rating as being conservative: don''t buy more capacity than needed. Choose low--duty-cycle machines only for maintenance or for intermittent welding. If portability is important, consider inverter units. Remote control of current and voltage is a plus if the welding operator is located away from the power source.Robotic ModelC5 and automatic applications CplemanPowermatePortable5 generally GallonAirTank require high-duty-cycle power supplies, and controls and connections for interfacing to the robot or automatic feature.Supervisory control of the process will prevent the welder from changing the welding procedures. Here, select a power supply or controller that enables the supervisor to program the procedures, then lock them into the control memory, Some power supplies or controllers offer the welder limited control of the process.Input power to power supplies can bc single and/or three phase, with voltage from 115 to 575 V and input ModelC5 frequencies of 50, 60, or 50/60 Hz. Note that CplemanPowermatePortable5 many inverter power supplies are designed to operate on both single- and three-phase GallonAirTank input, and have automatic input-voltage ModelC5 selection and linking.
