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 tungsten electrode touches the work piece 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 purpose: 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:
I.
DC – MMA
II.
DC – TIG
III.
DC - Pulse TIG
IV.
AC – MMA
V.
AC – TIG
VI.
AC - Pulse TIG
I. For DC MMA, polarity connection can be chosen according to different electrodes
，
please refer to
3.5
II. For DC TIG, DCEP is used normally (work piece 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.
