2AC TIGBalance controlprovides adjustable oxide removal — essential for creatingthe highest quality aluminum welds. These models provide extended ranges.Frequency controls the width of the arc cone and can improve directionalcontrol of the arc.AC WaveformsAdvanced square provides a fast freezing puddle, deeppenetration and fast travel speeds.Soft square for a soft buttery arc with maximum puddle controland good wetting action.Sine for customers that like a traditional arc. Quiet with good wetting.Triangular reduces the heat input and is good on thin aluminum.Fast travel speeds.Independent amplitude/amperage control allows EP and EN amperagesto be set independently to precisely control heat input to the work and electrode.DC TIGExceptionally smooth and precise arc for welding exotic materials.Pulse. Pulsing can increase puddle agitation, arc stability and travelspeeds while reducing heat input and distortion. These models provideextended ranges.Pulse WaveformsSquare provides a fast freezing puddle for ultimate arc control.Sine produces a reduced audible sound and provides a more fluid puddle that is good for overlaying applications.Triangular provides a quick-forming puddle while furtherreducing heat for thin materials.QuietPulse.™ Activate QuietPulse by selecting sine or triangular waveshapeto reduce audible noise.AC/DC StickDIG control allows the arc charac teristics to be changed for specificapplications and electrodes. Lower the DIG setting for smooth runningelectrodes like E7018 and increase the DIG setting for stiffer, morepenetrating electrodes like E6010. Hot Start™ adaptive control provides positive arc starts without sticking.AC frequency controladds stability for smoother welds when AC stick welding.Stick-Stuckdetects if the electrode is stuck to the part and turns the weldingoutput off to safely and easily remove the electrode.
