 3. Welding position. The first performance characteristic air and comprrssor to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position receiver welds. Also tanks good are rutile-fluxed electrodes-E6012 and E6013--that hold out-of-position air weld metal in place as it solidifies.4. Welding current. Covered comprrssor electrodes receiver run on AC, DC, or both. When welding DC, the positive lead typically connects to the electrode tanks (DCEP, or reverse polarity). Some suppliers air design electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with the available comprrssor current. For flux-cored-arc welding, shops use CV or CC types, 300 to 1,500 A, 25 to 50 V, rated 60- to 100-percent-duty cycle. CV types are more popular because wire-feed speed, set before welding, receiver controls welding current. Cc types require a variable-speed or tanks voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current air (AC or comprrssor DC) power supply with a steep volt-amp curve to minimize current change for variation in voltage or arc length. receiver They come rated to 1,500 A, 10 to tanks 75 V, at 40- to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, air gas valves, and cooling-water valves for high-current comprrssor welding. High-frequency arc start is useful when the maximum open-circuit receiver voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain a stable arc. Shielded-Metal-Arc tanks and air Welding (SMAW, comprrssor and receiver STICK)AWS tanks (American Welding Society) A5 specifications Set standards air for electronics for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their alloys and weld-surfacing. Designations comprrssor for covered electrodes carry the prefix receiver ''E''. Packaged to AWS specifications, electrodes come in boxes, cans, or other containers, labeled with their AWS specification tanks and trade name, quality control (heat or lot) number, supplier name, diameter and length, and weight of contents. Specifications air require that every electrode bc marked for identification comprrssor near with its numeric designation receiver the grip end.To select tanks a covered SMAW electrode, consider these factors, in approximate order of importance.
