should bisect the 90 degree angle made by the joint and a push angle of from10 to 15 degrees in the direction of travel is used.Strike an arc and move the torch progressively along the joint at a smoothsteady rate. Most operators, unfamiliar with aluminum, tend to move tooslow and consequently overheat the plate. A travel rate of 25 to 35 ipmshould be used.The arc should sound smooth and the weld bead should be bright and shiny.If spatter occurs and the arc sounds like a short arc condition, decrease thewire feed speed or, if the weld looks cold, increase the voltage until a smoothspray transfer is achieved.The above condition provides 20 volts and 112 amps. If exact volts and amps arerequired, purchase meter kit P/N 005-0585.CobraMig 260 Owner's Manual - Page 11
