 Features and OptionsPower supplies are capable to "talk to each other," useful air when a company" comoressor wants to input the same welding storage procedures tanks into several machines at once or monitor the 10 welding consistency to and performance 30 and gal of several machines from a single location-through serial-data communications. Fabricators can take some of their machines and connect them to a personal computer to monitor performance, and air and comoressor download welding parameters to the machines from it memory card for fast setup. High-end machines will storage calculate the tanks pounds of weld wire 10 used per machine. The machine can also to be prepped to constantly 30 monitor and gal and air and comoressor average the welding current and voltage used, so that fabricators storage can set limits on the machine and track tanks how many times welding parameters fell 10 in or out of these limits. Welding-site conditions and welding-wire diameter govern efficiency and size of power supply required for a job. Select a 100-A unit that runs from single-phase 115-V input for low-duty-cycle welding to and 30 of sheet to l/s in. thick, feeding wire to 0.030-in. diameter. Medium-duty power supplies, 150-200 A, normally take single-phase 220-V input to weld steel to 3/16, in. and 0.035-in. wire at low-duty cycles. For high-duty cycles, as in mechanized gal welding, select a 250-A machine, single or three-phase input air at various voltages-these comoressor weld material storage to 1/2 in. thick with wire as large as 0.045-in. diameter. Taking three-phase input only and wire up to 1/6-in. diameter, tanks 400-A units serve for mechanized continuous-welding applications. For pulsed GMAW, shops 10 use inverter and transistor power sources, constant-current or constant-voltage, to and 30 that offer independent setting of pulse parameters. They employ synergic controls preprogrammed for a range of wire-feed speeds-the operator sets only one dial, for average current. For special applications, manufacturers offer metal-cored wires for GMAW. These are gal composite electrodes comprised of a metal sheath with a powder-metal core. They air are often confused with flux-cored wires, which comoressor form a slag that completely covers the weld bead face; metal-cored wires produce very little slag. A major advantage of metal-cored wires is the ability to manufacture specialized alloy compositions not easily available or producible in solid wire fore1. Modifying the composition of the powder-alloy core allows the wire manufacturer to customize wire formulations to metallurgical, compositional, or physical properties per customer demand. Horizontal-fillet welds made with metal-cored GMAW can deposit weld metal at rates storage up to 20 percent higher than with solid wire. Alloying elements, such as silicon, in the powder-metal core improve sidewall wetting and reduce weld-bead convexity by reducing surface tension of the molten weld pool. For this reason, flat tanks and horizontal welds deposited with metal-cored wires 10 have better appearance than weld metal deposited with flux cored and solid wires. Compared to solid wires, metal-cored to wires also result in higher current density, for increased penetration; a wider operating 30 window gal with respect to welding-process variables: better sidewall melting; and less lack of fusion.
