 Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece and the length of time it takes to deposit aircompreasertank the longest weld on the thickest material. Duty cycle is the key factor to consider when selecting a power source. Once aircompreasertank the engineer has determined the current and voltage needed to accomplish the 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 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 rest the machine for the next four minutes to avoid overheating the unit. 3. Welding position. The first performance characteristic to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light aircompreasertank slag that makes for rapid solidifying of 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 aircompreasertank 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 aircompreasertank electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with the available current.
