2.1 Brief Introduction
The Taurus TIG200ACDC-HF-P welding machine incorporates the latest pulse width modulation
(PWM) technology and insulated gate bipolar transistor (IGBT) power module. These can change work
frequency to medium frequency thus replacing the traditional frequency transformer with the medium
frequency cabinet transformer. This has led to a smaller size, portable and light-weight machine of
lower power consumption.
The parameters of the Taurus TIG200ACDC-HF-P on the front panel can be adjusted continuously and
stepless for instance 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. When welding it selects high frequency and high voltage for arc ignition ensuring the
success ratio of ignition arc.
Taurus TIG200ACDC-HF-P Characteristics：
➢ MCU control system - responds immediately to any changes.
➢ High frequency and high voltage ensure the success ratio of ignition arc. The reverse polarity
ignition ensures good ignition behavior in TIG-AC welding.
➢ AC arc-break is avoided - even if arc-break occurs it will be kept stable by HF.
➢ Pedal control of welding current.
➢ TIG/DC operation - when the tungsten electrode touches the workpiece, the current will drop
to short-circuit to protect the tungsten..
➢ Intelligent protection protects against over-voltage, over-current and over-heat by means of
output current cut off confirmed by lit alarm lamp on the front panel. It can self-protect and
prolong the machines life.
➢ Double purpose - AC inverter TIG/MMA and DC inverter TIG/MMA with excellent
performance on Al-alloy, carbon steel, stainless steel and titanium.
