1.For DC MMA, polarity connection can be chosen according to different electrodes
，
please refer
to §3.5
；
2.For AC MMA, magnetic flow caused by invariable DC polarity can be avoided
；
3. For DC TIG, DCEP is used normally (workpiece connected to positive polarity, while torch
connected to negative polarity). This connection has many characters, such as stable welding arc,
low tungsten pole loss, more welding current, narrow and deep weld;
4. For AC TIG (rectangle wave), arc is more stable than Sine AC TIG. At the same time, you can
not only obtain the max penetration and the min tungsten pole loss, but also obtain better clearance
effect.
SANARG 180AP welding machine is suitable for all positions welding for various plates made
of stainless steel, carbon steel, alloyed steel, titanium, aluminum, magnesium, cuprum, etc, which is also
applied to pipe installment, mould mend, petrochemical, architecture decoration, car repair, bicycle,
handicraft and common manufacture.
