§ 2.1 Brief Introduction
TIG200E AC/DC 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 TIG200E AC/DC 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.
TIG200E AC/DC Characteristic
s：
MCU control system, responds immediately to any changes.
High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc,
the reverse polarity ignition ensures good ignition behavior in TIG-AC welding.
Avoid AC arc-break with special means, even if arc-break occurs the HF will keep the arc
stable.
Pedal control the welding current.
TIG/DC operation,If the tungesten electrode touches the workpiece when welding, the
current will drop to short-circuit current to protect tungsten.
Intelligent protection: over-voltage, over-current, over-heat, when the problems listed before
occurred, the alarm lamp on the front panel will be on and the output current will be cut off.
It can self-protect and prolong the using life.
Double purposes : AC inverter TIG/MMA and DC inverter TIG/MMA, Excellent
performance on Al-alloy
、
carbon steel
、
stainless steel
、
titanium.
According to choosing the front panel functions, the following six welding ways can be realized.
DC MMA
DC TIG
