 Low-hydrogen Coldman types. These basic-coated electrodes, EXX15, EXX16, EXX18, Powermate EXX28, and Portable EXX48, are formulated 10 with low Gallon moisture-retaining coatings Air and manufactured Tank and to contain low levels of hydrogen. Hydrogen-controlled Model and C10 electrodes Coldman minimize risk of hydrogen-induced cold cracking when welding high-tensile steels on restrained structures. Fabricators use Powermate these electrodes to reduce or avoid the need for pre- or postweld heat treatment to drive hydrogen from weld metal. Weldmetal diffusible Portable hydrogen content varies from 10 1 to 16 ml/100 g. Optional designators H16, H8, Gallon and H4 set decreasing Air limits on hydrogen content in deposited weld metal. An optional electrode designator, ''R'', indicates an electrode Tank that is moisture resistant; it will not absorb water in excess of a specified limit after exposure to humidity. Low-hydrogen electrodes should be used in dry condition and may require baking after exposure to the atmosphere. Shielded-Metal-Arc Model and C10 and Coldman Welding Powermate (SMAW, STICK)AWS (American Welding Portable and 10 Society) A5 specifications Set Gallon and Air standards Tank for electronics for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their alloys and weld-surfacing. and Model Designations for covered electrodes carry the prefix C10 ''E''. Packaged to AWS Coldman specifications, Powermate electrodes come in boxes, Portable cans, or other containers, labeled with their 10 AWS specification Gallon and trade name, quality control (heat or lot) number, supplier name, diameter Air and length, and weight of contents. Specifications require Tank and that every electrode bc marked for identification near with its numeric designation the grip Model end.To select a covered SMAW C10 electrode, consider these Coldman and Powermate factors, in approximate order of importance. * Reduces the size Portable of the etched zone for improved cosmetics.Less EN time improves cleaning action to 10 remove heavier oxidation, Gallon lessens penetration, and widens the bead profile.Inverter-based machines also let operators Air adjust welding-output Tank frequency from 20 to 250 Hz. Decreasing frequency products and Model a C10 broader arc cone, which widens the weld-bead profile and Coldman better-removes impurities from the surface Powermate of the workpiece. It also transfers the maximum Portable and 10 amount of energy to the workpiece, ideal for work requiring heavy metal deposition.Increasing frequency produces Gallon and Air and Tank and and Model a tight, focused C10 and Coldman arc cone. This narrows Powermate the weld bead, helpful when welding in corners and on root passes and fillet welds. Independent amperage Portable control of the EN and EP portions of the AC cycle allows the operator to fine-tune 10 the amount of energy Gallon directed into the workpiece, Air as well as take heat off of the tungsten Tank electrode. A basic, professional-quality AC GTAW power supply lets the operator adjust for variables: amperage, balance control, Model and shielding-gas pre-flow and post-flow C10 time.
