1.2 Introduction
TitanTig 200P ACDC Pro welding machine adopts the latest pulse width modulation (PWM) technology
and insulated gate bipolar transistor (IGBT) power module, which can change work frequency to medium
frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium
frequency transformer. Thus, it is characterized with portable, small size, light weight, low consumption
and etc.
The parameters of TitanTig 200P ACDC Pro on the front panel all can be adjusted continuously and
steplessly, such as start current, crater arc current, welding current, base current, duty ratio, upslope time,
downslope time, pre-gas, post-gas, pulse frequency, AC frequency, balance, hot start, arc force and arc
length etc. When welding, it takes high frequency and high voltage for arc igniting to ensure the success
ratio of igniting arc.
TitanTig 200P ACDC welding machine is suitable for all positions welding for various plates made of
stainless steel, carbon steel, alloyed steel, titanium, aluminium, magnesium, cuprum, etc, which is also
applied to pipe installment, mould mend, petrochemical, architecture decoration, car repair, bicycle,
handicraft and common manufacture.

DC MMA
, polarity connection can be chosen according to different electrodes.
AC MMA
, magnetic flow caused by invariable DC polarity can be avoided
；
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;
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.
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 workpiece 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.
