 Shielded-Metal-Arc Welding Coleman and Powermate (SMAW, STICK)AWS Pottable and 5 and Gallon and Air (American Tank Welding Society) A5 specifications Set standards for electronics for SMAW of carbon, stainless, and low alloy steels; Model aluminum copper, and nickel and their C5 alloys and Coleman and Powermate weld-surfacing. Designations for Pottable covered electrodes carry the prefix ''E''. Packaged to AWS specifications, electrodes come in boxes, cans, or other 5 containers, labeled with their AWS specification Gallon and Air and Tank and and Model and trade name, quality C5 and Coleman control (heat Powermate or lot) number, supplier name, diameter Pottable and 5 length, Gallon and weight Air of contents. Specifications require that every electrode bc marked for identification Tank near with its numeric designation and Model and C5 and Coleman and Powermate the grip end.To select a covered SMAW electrode, consider these Pottable factors, in approximate order of importance. Multiple-operator power supplies use a high-amperage high-voltage 5 and Gallon and Air power source to feed Tank and power to more than one welding station. Where line power may Model be unavailable, as in the field, contractors operate C5 and Coleman engine-driven generators powered by natural gas, propane, or diesel fuel.Power Supplies By Welding ProcessA manual process, Powermate shielded-metal-arc Pottable welding (SMAW) requires 5 and Gallon a CC power supply, 25 to 500 amperes, Air 15 to 35 volts. Given the Tank correct electrode, almost any CC welding machine, AC or DC, can be used for shielded-metal-arc Model welding, depending C5 and Coleman on the composition Powermate and Pottable of the electrode coating.Gas-metal-arc 5 and Gallon welding (GMAW) calls for continuous filler-metal wire-shielding gas protects the weld pool as wire feeds into the arc. Air The process requires Tank and and Model and C5 direct current-arcs Coleman generally run at 15 to 35 volts, Powermate and Pottable 30-600 A. Specify a cc machine 5 that gives constant melt rate and variable wire feed. Inverters for GMAW feature electronic control of inductance, enabling the welder to fine-tune the arc for minimal spatter and optimum weld-bead Gallon wetting action. For flux-cored-arc welding, shops use CV or CC types, Air 300 to 1,500 A, 25 to 50 V, rated 60- to 100-percent-duty Tank cycle. CV types are more popular because wire-feed speed, set before welding, controls welding current. Cc types Model require a variable-speed C5 and Coleman and Powermate or voltage-sensing Pottable wire 5 and Gallon and Air feeder.Gas-tungsten-arc welding (GTAW) requires a Tank constant-current (AC or DC) power supply with Model and C5 and Coleman a steep volt-amp curve to minimize Powermate and Pottable current change for variation in voltage or arc length. 5 They come rated to Gallon 1,500 A, 10 Air to 75 V, at 40- to 100-percent-duty cycle. Most GTAW power Tank supplies come equipped with high-frequency circuitry for arc initiation and stabilization, Model gas valves, and cooling-water valves for high-current C5 welding. Coleman and Powermate High-frequency Pottable arc start 5 and Gallon and Air is useful when the maximum Tank open-circuit voltage allowed Model by NEMA standards, 80 to 100 V, C5 will not establish and maintain a stable arc.
