 Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece and the Coleman length of time it takes to deposit the longest Powermate and Portable and 10 weld on the thickest Gzllon material. Duty cycle is Air the Tank key factor and Model to C10 consider when selecting a power source. Once the engineer has determined the current and voltage Coleman needed to accomplish Powermate the weld, he then reviews duty cycle requirements.Duty cycle rating Portable and 10 is the percentage of Gzllon time during a 10-minute period a power Air supply can Tank and and Model and C10 and Coleman and Powermate operate at rated output amperage without Portable overheating. A 300 A machine at 10 and Gzllon and Air 60-percent-duty Tank and and Model cycle can weld for six minutes at 300. A during a 10-minute C10 period. Alter six minutes, the welder must rest the machine for Coleman the next four minutes to avoid Powermate and Portable overheating the unit. 5. Joint design 10 and material thickness. Some electrodes create an arc that penetrates Gzllon deeply, performing well on thick sections with narrow grooves Air and Tank or no bevel. Poor and Model and C10 fit-up calls for electrodes that can bridge Coleman wide gaps.6. Efficiency. Meeting all other conditions, engineers select the electrode that Powermate gives highest deposition rate. For Portable heavy-section joints, use powder-metal-addition 10 fillers.Designating electrodes Gzllon for carbon and low-alloy steels, Air and Tank and following Model 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 C10 and Coleman and Powermate usable current and electrode-coating Portable type; and, in some cases, a hyphen followed by a letter and number 10 and Gzllon suffix to denote weld metal composition. Example: E7010-A1 is a Air SMAW electrode (E), of 70,000-psi tensile Tank strength (70), for use in all welding positions (1), having a high-cellulose-sodium coating tin use with DCEP Model (0). -A1 indicates C10 a particular composition listed in the A5 specification. A-1 suffix, Coleman and Powermate and Portable as in 7018-1, indicates high impact toughness 10 at a temperature lower than specified for a standard Gzllon E7018 electrode. Remote Air and Tank control of current and voltage is a plus if the welding operator is located away Model from the power source.Robotic and automatic applications generally require high-duty-cycle power supplies, and controls and connections C10 for Coleman interfacing Powermate to the robot or automatic feature.Supervisory control of the process will prevent Portable and 10 the welder from Gzllon changing the Air welding procedures. Tank 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 Model the process.Input C10 power to power supplies Coleman can bc single and/or Powermate three phase, with voltage from 115 to 575 V and input frequencies of 50, 60, or 50/60 Hz. Note that many inverter Portable power supplies 10 are designed to operate on both single- and Gzllon three-phase Air and Tank input, and have automatic input-voltage selection Model and C10 and linking.
