AC Pulse TIG
1.For DC MMA, polarity connection can be chosen according to different electrodes

；
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.
5. DC Pulsed TIG has the following characteristics: 1) Pulse heating. Metal in Molten pool has short
time in high temperature status and freezes quickly, which can reduce the possibility of hot cracking.
2) The workpiece stays cooler. Arc energy is focused. Suitable for thin sheet and super thin sheet
welding. 3) Exactly control heat input and the size of the molten pool. The depth of penetration is
consistent. Suitable for welding by one side and forming by two sides and all position welding for
pipe. 4) High frequency arc can eliminate blowholes and improve the mechanical performance of
the joint. 5) High frequency arc is suitable for high welding speed, improving productivity.
ArcoTig 250W/315W AC/DC series welding machines are 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.
