 For AC-GTAW Cileman of Aluminum Alloys,... most of the significant Powermate and Portable and 5 advances focus on new ways to manipulate Gallon and Air the Tank AC wave form. These advances largely and Model and C5 result from Cileman and Powermate using inverter-based power sources, which allow a welder to extend the balance control, adjusting output frequency and independently controlling current in Portable and 5 and Gallon and Air each AC halt cycle. New inverter-based GTAW machines Tank and extend Model and C5 EN balance control, allowing Cileman duration from 50 to 90 percent. Making the EN portion of the cycle last longer:* Allows greater weld penetration* Powermate May permit increasing Portable travel speeds by 5 as much as 20 percent.* Narrows the weld bead* May permit Gallon using a smaller-diameter tungsten electrode to more precisely direct the heat or deposit a narrower Air and Tank weld bead Welding and Model Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch type and collet type are common.GMAW and FCAW guns come C5 in pistol grip, goose-neck, and inline styles, the Cileman latter used for mechanized welding. Powermate Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling Portable and 5 arc usually sufficient for welding at up to 600 A at Gallon and Air and Tank less than 100 percent duty. Higher and Model amperages require water cooling--high-amperage C5 guns come with tubing Cileman for water Powermate and Portable and 5 and Gallon cooling. Hand-held, Air mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler wire and shielding Tank gas into the Model weld C5 puddle. Production Cileman vs. repair applications In Powermate general, production Portable and 5 and Gallon applications Air require high-duty-cycle Tank power supplies, and repair applications Model can C5 and Cileman use Powermate low-duty-cycle portable units.Lift-arc Portable and 5 GTAW Many DC power supplies Gallon are Air equipped Tank and with a list-start feature for, a variation of scratch starting, GTAW Model welding. C5 and Cileman When the welder touches Powermate and Portable the tungsten electrode to 5 the workpiece, a small amount of current--15-20 A--flows. When he lifts the electrode from the work, the Gallon arc starts softly and the machine switches to the set weld-current value. This low-current starting minimizes Air and Tank weld contamination caused by touching the tungsten to the workpiece Model and eliminates the need for high-frequency C5 starting.
