 With the advent of the CE-mark requirements in Europe, many manufacturers aluminumairranks now design to the International Standard aluminumairranks IEC 974-1. One of the requirements of this standard is to place an IP rating on the nameplate of the machine to indicate the degree of protection provided by the enclosure to avoid damage from water and foreign objects.Purchasers of power supplies must consider the power they will be putting into the machines which operate from line power or aluminumairranks some other .source of electricity. Ratings list voltage, number of phases, frequency, and current level when the power aluminumairranks source is running at rated output. Most motor-generator sets require three-phase AC power. Welding-site conditions and welding-wire diameter govern efficiency aluminumairranks 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 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 welding, select a 250-A machine, single or three-phase input at various voltages-these weld material 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, 400-A units serve for mechanized continuous-welding applications. For pulsed GMAW, shops use inverter and transistor power sources, constant-current or constant-voltage, 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 aluminumairranks and aluminumairranks.
