Duty-Cycle RatingPower-supply rating depends on the type and thickness duracraft of the workpiece and the length of time it takes to deposit the drill longest weld on the thickest material. Duty cycle is the key factor to consider when selecting a power source. Once the engineer presses has determined the current and voltage needed to accomplish the weld, he then reviews duty cycle requirements.Duty cycle duracraft 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 drill for the next four minutes to avoid overheating presses the unit.

The group also declared that Orlando, Fla., would serve as the only location for future shows. The change in date and location duracraft will drill take effect in 2009 and will run through 2017. NAFEM executives said the presses decision would help foodservice operators with their planning duracraft cycles and needs.The group''s drill Customer Advisory Task Force, which presses and duracraft represents more than 70 percent of the multiunit operators in North America, drill said shifting presses and duracraft the show to the first quarter of the year would allow them not only to plan better but also to incorporate what they learn into their operations.

3. Welding position. The first performance characteristic to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid drill solidifying presses of the weld metal good for-out-of-position welds. Also good are duracraft rutile-fluxed electrodes-E6012 and E6013--that hold out-of-position weld metal in place as it solidifies.4. Welding current. Covered drill 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 presses weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with the available current.
