Product Overview
2
The JT-200D and 315D are a series of digital controlled AC/
DC pulsed TIG/MMA inverter welding machines with
excellent performance and utilising advanced technology
system. They It have various AC/DC modes such as AC
square-wave TIG, AC pulsed TIG, DC TIG, DC pulsed TIG,
AC MMA (SMAW), DC MMA (SMA, TIG spot welding (DC,
pulsed or AC), and composite waveform TIG, etc., and can
be widely used in high quality welding of a wide range of
materials.
The design uses both advanced and mature technologies to
ensure reliability and extended machine life.
Key features
Advanced digital control
The machines adopt advanced MUC intelligent digital
control technology, and all the major functions are
performed through the software. It is this digital control that
provides a much improved performance when compared
with the traditional welding machines.
Advanced inverter technology
The primary inverter frequency is 100 KHz, which greatly
reduces the volume and weight of the welder. The great
reduction in magnetic and resistance loss obviously
enhances the transformer e
ffi
ciency and energy saving
e
ff
ect. The working frequency is beyond audio range, which
almost eliminates the noise pollution.
Automatic protection functions
When the mains voltage fluctuates sharply, the welding
machine will automatically stop working with the fault
information displayed, and it will automatically recover after
the mains voltage turns stable. In the case of over current or
overheating, the machine will stop working automatically
with the fault information displayed. Such protection
functions greatly increase the lifespan of the machine.
Excellent consistency and stable performance
The machines adopt intelligent digital control, so it is not
sensitive to the change of parameters of components. That
is,the performance of welding machine will not be a
ff
ected
by the change of the parameters of certain components. It
can also compensate for any change of the working
environment such as temperature and humidity, etc.
Therefore, the consistency and stability of the digital control
welder is better than that of traditional welder.
Parameters are easy to adjust and software easy to update
The control of parameters for a welding machine with
intelligent digital control is much easier and more accurate,
because its main functions are achieved through software.
To change the a function or some of the parameters, you do
not need to change the circuit, and the only thing you have
to do is to download the updated software.
User-friendly interface
This machine adopts international standard graphic
language interface, which is simple, clear, intelligible, and
convenient for users’ operation.
Practical welding process management function
The machine allows users to divide the welding parameters
into five groups, according to di
ff
erent techniques during
operation, each of which can complete a particular welding
task. It undoubtedly facilitates the technical standardisation
management in welding production.
High-quality MMA welding
MMA welding performance is significantly improved with an
excellent control algorithm: easier to ignite arc, stable
welding current, little spatter, no electrode sticking, good
shaping, and adaptable to the change of length or section
of welding cable.
High-quality TIG welding
Improved digital technology for constant current ensures
the low noise and a high stability of arc quality as well. The
mature control algorithm provides users with a convenient
and practical approach to control the current. Totally 20 TIG
operation modes, including the typical 2T/4T, and 4 of them
