III. DC Pulsed TIG has the following characters: 1) Pulse heating. Metal in Molten pool has short time
on high temperature status and freezes quickly, which can reduce the possibility to produce hot
crack of the materials with thermal sensitivity. 2) The work piece gets little heat. Arc energy is
focused. Be 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 even. Be suitable for welding by one
side and forming by two sides and all position welding for pipe. 4) High frequency arc can make
metal for microlite fabric, eliminate blowhole and improve the mechanical performance of the
joint. 5) High frequency arc is suitable for high welding speed to improve the productivity.
IV. For AC MMA, magnetic flow caused by invariable DC polarity can be avoided.
V. 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.
ionTig 200 AC/DC 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, mold mend, petrochemical, architecture decoration, car repair, bicycle,
handicraft and common manufacture.
MMA - Manual Metal Arc welding;
PWM - Pulse-Width Modulation;
IGBT - Insulation Gate Bipolar Transistor
TIG - Tungsten Insert Gas welding
