1.1 Brief Introduction
TIG V1841 V241 V341 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, its characterized with portable, small size, light weight, low
consumption and etc.
The parameters of TIG V1841 V241 V341 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 etc. When welding, it takes high frequency and high
voltage for arc igniting to ensure the success ratio of igniting arc.
TIG V1841 V 241 V341 AC/DC Characteristics:
◆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.
◆In DC TIG without HFopertation, If the tungsten electrode touches the workpiece
when welding, the current will drop to short-circuit current to protect tungsten.
Intelligent protection: over-current, over-heat, when the mentioned problems
◆
occoured, 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.
