Product Overview
The main circuit of this product uses full-bridge converng
technology based on the tradional PWM (pulse width
modulaon) and current control mode, It uses insulated gate
bipolar transistors (IGBT) as its switching devices. By
adopng advanced so switching technology, the switching
loss of the switching device is greatly reduced, thereby the
product eciency is increased, and consequently the
reliability and stability of this machine is improved. By
adopng internaonally advanced DSP digital technology
and with abundant funcons and good performance, this
machine is an all-digital inverter welder with pulse MIG/
MAG and standard MIG/MAG. When compared with the
tradional welding machine, it mainly has the following
characteriscs.
Abundant funcons: This product has many welding modes
available, such as MIG/MAG, pulse MIG/MAG and double-
pulse MIG/MAG, etc. At the same me, there are many
oponal operaon modes under each welding mode, such as
spot welding, 2T and 4T, etc. Welding wires of dierent
diameters between 0.8mm and 1.6mm are all applicable to
this product. Users may choose welding wires of dierent
materials and dierent diameters to weld dierent metals
and alloys according to dierent welding requirements. In
addion, parameters such as welding current, welding
voltage, ignion current, crater lling current, ignion me,
crater lling me and pulse frequency can be set via the easy
to use computer interface.
High precision and good consistency: The composion
characterisc of the tradional welding machines
determines that their performance completely depends on
the parameters of their components. That is to say, the
inconsistency in the parameters of components directly
leads to the inconsistency in the performance of the welding
machines. However, it cannot be guaranteed that the
components made by any manufacturers are completely
consistent in their parameters. Besides, highly precise
control cannot be obtained due to non-ideal features of the
operaonal amplier. Therefore, even for the welding
machines of the same brand, they oen dier from each
other. In addion, welding performance of the machine may
change to some extent, since parameters of the components
may vary according to the environment such as temperature
and humidity, etc.
This product uses a digital circuit, for which most of the
parameters are set via soware, and it is insensive to the
change of the parameters of the components. Therefore, the
consistency and stability of digital welding machine is beer
than that of tradional welding machine.
High reliability: Overheang protecon, overcurrent
protecon and input under voltage/overvoltage protecon
are all available for this product, which contributes a lot to
the reliability improvement of this product, and meanwhile
facilitates the maintenance and repair of this product.
Excellent welding performance: In order to improve the
welding performance to meet the higher requirements of
welding process, experts at home and abroad have done a
lot of work and put forward many excellent mathemacal
control models. However, such complicated mathemacal
models are very dicult to implement on the tradional
analog welding machines. Instead, they are well applied in
the digital welding machines.
Convenient opmizaon and upgrade of welding
performance: With the development and improvement of
the welding process, it is certainly required that our welding
machine has an excellent welding performance. All the
welding performance of this product is achieved by
soware. Therefore, the welding performance of this
welding machine can be opmized and upgraded by
upgrading the soware without changing any hardware
circuits.
User-friendly design: Dierences in user and using occasion
were taken into consideraon when designing this product,
so as to meet the personalized requirements of users to the
largest extent. For example, this product provides a variety
of welding torch operang modes and user-dened modes.
This product adopts synergic design. That is to say, users
only need to adjust one of the parameters, and other related
parameters would change respecvely to achieve the
opmal matching. It is unnecessary to set each parameter
independently. For example, when the user changes the
welding current, parameters such as welding voltage, wire
feed speed and base metal thickness would change
respecvely. Of course, users can make ne-tuning on
certain parameters such as welding voltage to adapt to their
welding habits.
Energy-saving and small size: This machine adopts
advanced IGBT inverter technology, which reduces the
volume and weight of the welding source and the whole
machine, improves the eciency and power factor of the
power supply, and brings signicant energy saving eect.
