2. GENERAL DESCRIPTION
2.1 Model coding
1) Model:MIG350P(N316) MIG400P(N317)
2) Coding description: “MIG” refers to MIG/MAG welding;“350/400” refers to the rated welding
current;“P” refers to pulse.
2.2 Product characteristics
The main circuit of this product adopts full-bridge converting technology based on the traditional
PWM (pulse width modulation) and current control mode, and it adopts insulated gate bipolar transistor
(IGBT) as its switching device. By adopting advanced soft switching technology, the switching loss
of the switching device is greatly reduced, the product efficiency is increased, and consequently the
reliability and stability of this machine is improved. By adopting internationally advanced DSP digital
technology and with abundant functions and good performance, this machine is an all-digital inverter
welder with pulse MIG/MAG and standard MIG/MAG. When compared with the traditional welding machine,
it mainly has the following characteristics.
1)
Abundant functions: This product has many welding modes available, such as MIG/MAG, pulse MIG/MAG
and double-pulse MIG/MAG, etc. At the same time, there are many optional operation modes under
each welding mode, such as spot welding, 2T and 4T, etc. Welding wires of different diameters between
0.8mm and 1.6mm are all applicable to this product according to different capacity. Users may choose
welding wires of different materials and different diameters to weld different metals and alloys
according to different welding requirements. In addition, parameters such as welding current,
welding voltage, ignition current, crater filling current, ignition time, crater filling time and
pulse frequency can be set via the human-computer interaction interface. Besides, current, voltage
and wire feed speed can be calibrated by software for this machine.
2) High precision and good consistency: The composition characteristic of the traditional 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 operational amplifier.
Therefore, even for the welding machines of the same brand, they often differ from each other.
In addition, 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
adopts digital circuit, for which most of the parameters are set via software, and
it is insensitive to the change of the parameters of the components. Therefore, the consistency
