Argon arc welding machine on the current mourning, and clean up the pulse of these two adjustment knob in welding 1mm aluminum how to use?

Attenuation current is the closing arc current, when the current is larger arc break, the workpiece is easy to produce arc pit, attenuation current role is to fill the arc pit, arc break current gradually reduced. \x0d\ cleaning pulse is this a new call? The terminology should be called clean width. Clean width only works in AC welding. \x0d\\ TIG welding aluminum welding using AC welding, silicon controlled models, inverter models output is controlled square wave, equalization of positive and negative conduction time is equal, clean width is to regulate the positive and negative square wave conduction time. \x0d\ When the cleaning width is adjusted when the positive conduction time is lengthened, at this time the workpiece melts y, the weld channel is narrow, the tungsten electrode consumption \x0d\ When the cleaning width is adjusted when the negative conduction time is lengthened, at this time the workpiece melts shallowly, the weld channel is wide, the tungsten electrode consumption is small \x0d\ When the cleaning width is adjusted for welding of aluminum 1mm, the cleaning width should be adjusted to a large weld channel wide melting depth is shallow not easy to collapse and perforated, the attenuation of the current because you do not have much welding current can not be adjusted
