MIX ARC WELDING
Razor
32OAC/DC TIG-MMA
MIX Arc is an innovative welding solution for high current AC welding applications, This function of MIX AC/DC makes it possible to
modulate the welding current, alternating a period of TIG AC with a period of TIG DC-. This means that the efficiency of AC TIG welding
can be combined with the high penetration of DC TIG welding, obtaining higher welding speeds, establishing the weld puddle quicker on
cold workpieces, increase weld penetration and reduces tungsten tip temperature. Other benefits are the welding of extremely diverse
material thickness eg., 1mm to 10mm and helping bridge and close gaps between two joints during welding.
The resuilt in welding is simialr to AC PULSE welding but with a stronger arc force in the molten pool making it particulary suitable for
welding thicker material.
During the AC period of the arc the oxide film is broken, the welding arc becomes wider and the surface impurities are flushed out.
During the DC period of the arc the arc becomes narrower, the molten pool is drawn deeper into the workpiece improving penetration.
The operator adjustable parameter is the percentage of AC waveform compared to DC- waveform, which can be varied from 5~95%. It
is good practice never to exceed the value of 50% DC - waveform, which would otherwise impair the oxide removal and flushing portion
of the weld and effect the appearance of the weld bead.
MIX ARC WELDING
MIX ARC can be used with the different AC wave forms of Square Wave, Triangle Wave and Sinusiodal Wave.
