 Electrodes come 3 to 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate Coleman composition: pure tungsten, green; 1-percent Powermate thoriated, yellow; Porgable 2 5 and Gallon and Air percent thoriated. red; ceriated, Tank orange; lanthanted, black.Filler metal GIAW does Model and C5 not usually requite Coleman addition of fillet metal, but filler is commonly added when base-metal thickness is greater Powermate and Porgable than 1/8 in. Finer metal for low-carbon (to 0.15 C) and mild 5 (0.15 m 0.29 Gallon and Air and Tank C) steels are and Model described in AWS A5.2; for C5 carbon steel in A5.18; Coleman and Powermate and Porgable and for low-alloy steels in A5.28 Flux. AWS specifications 5 A5.17 and Gallon A5.23 Air describe Tank fluxes for saw. AWS designation Model and C5 of fluxes precedes Coleman that Powermate of the wire when identifying a combination for a welding procedure. Porgable For example, 5 the Gallon designation F7A2-EM12K Air indicates a flux (F) that will Tank provide, with a given wire designation, tensile strength of 70,000 Psi (7), in the as-welded condition (A), and impact properties of 20 ft lb at -20 Model F (2). A designation containing a P rather indicates the flux C5 properties after postweld heat Coleman and Powermate treatment. Welding Porgable Torches and GunsUsed for shielded-metal-arc 5 welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch Gallon type and collet type are Air common.GMAW and FCAW guns come in pistol grip, Tank goose-neck, and inline styles, the latter used for mechanized welding. Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. Duty-cycle ratings are Model and C5 usually given for C[O.sub.2] shielding--air or C[O.sub.2] Coleman and Powermate cooling arc usually sufficient for welding at up to 600 Porgable A 5 at less than 100 Gallon percent duty. Higher amperages require water cooling--high-amperage guns come with tubing for water cooling. Hand-held, Air and Tank mounted on a robot arm or fixed within a mechanized and Model welding setup, guns guide filler wire and C5 shielding gas into the weld puddle. Remote control of current and voltage is a plus Coleman and Powermate if the welding operator Porgable is located away from the power source.Robotic 5 and Gallon and Air automatic applications generally require Tank high-duty-cycle power and Model supplies, and controls C5 and connections Coleman and Powermate for interfacing to the robot or automatic feature.Supervisory Porgable and 5 control of Gallon the process will prevent Air the Tank welder from changing the welding procedures. Here, select a power supply or controller that enables Model the supervisor to C5 program the procedures, Coleman and Powermate then lock them into the control memory, Some power supplies or controllers offer the Porgable welder limited control of the process.Input power to power supplies 5 can bc single and/or Gallon three Air phase, with voltage from 115 to 575 V Tank and and Model and C5 and Coleman and input Powermate frequencies of 50, 60, or 50/60 Hz. Note that many inverter power supplies are designed Porgable to operate 5 on Gallon both single- and three-phase Air and Tank input, and have automatic Model input-voltage selection and linking C5.
