other people or towards your body.
Always ensure machine covers and protecve
devices are in operaon.
Precauons against re and explosion
Check and be sure the area is safe and clear of
inammable material before carrying out any
welding.
Accidental contact of electrode to metal objects
can cause arcs, explosion, overheang or re.
Avoid causing res due to sparks and hot waste or
molten metal.
Ensure that appropriate re safety devices are
available near the cung/welding area.
Do not cut/weld fuel and lubricant containers, even
if empty. These must be carefully cleaned before
they can be cut/welded.
Always allow the cut/welded material to cool
before touching it or placing it in contact with
combusble or ammable material.
Do not work in atmospheres with high
concentraons of combusble fumes, ammable
gases and dust.
Always check the work area half an hour aer
cung to make sure that no res have begun.
Risks due to magnec elds
The magnec elds created by high currents may
aect the operaon of pacemakers or
electronically controlled medical equipment.

Wearers of vital electronic equipment should
consult their physician before beginning any arc
welding, cung, gouging or spot welding
operaons.
Do not go near welding equipment with any
sensive electronic equipment as the magnec
elds may cause damage.
RF Declaraon
Equipment that complies with direcve 2004/108/
EC concerning electromagnec compability (EMC)
and the technical requirements of EN60974-10 is
designed for use in industrial buildings and not for
domesc use where electricity is provided via the
low voltage public distribuon system. Dicules
may arise in assuring class A electromagnec
compability for systems installed in domesc
locaons due to conducted and radiated emissions.
In the case of electromagnec problems, it is the
responsibility of the user to resolve the situaon. It
may be necessary to shield the equipment and t
suitable lters on the mains supply.
LF Declaraon
Consult the data plate on the equipment for the
power supply requirements.
Due to the elevated absorbance of the primary
current from the power supply network, high power
systems aect the quality of power provided by the
network. Consequently, connecon restricons or
maximum impedance requirements permied by
the network at the public network connecon point
must be applied to these systems.
In this case the installer or the user is responsible
for ensuring the equipment can be connected,
consulng the electricity provider if necessary.
Materials and their disposal
The equipment is manufactured with materials,
which do not contain any toxic or poisonous
materials dangerous to the operator.
When the equipment is scrapped, it should be
dismantled separang components according to the
type of materials.
Do not dispose of the equipment with normal
waste. The European Direcve 2002/96/EC on
Waste Electrical and Electronic Equipment states
the electrical equipment that has reached its end of
life must be collected separately and returned to an
environmentally compable recycling facility.
Handling of compressed gas cylinders and
regulators
All cylinders and pressure regulators used in
welding operaons should be handled with care.
Never allow the electrode, electrode holder or any
other electrically “hot” parts to touch a cylinder.
Keep your head and face away from the cylinder
valve outlet when opening the cylinder valve.
Always secure the cylinder safely.
Never deface or alter any cylinder

pulsed TIG welding, AC-DC hybrid TIG welding and
coated electrode MMA welding (DC, AC). It can be
used in a wide range of welding operaons with
various types of materials. The unique electrical
structure and air duct design inside the machine
can accelerate the dissipaon of the heat generated
by the power devices, thus increasing the
connuous load rang of the machine. Due to the
unique air duct heat dissipaon eciency, the
damage to the power devices and the control
circuit caused by the dust sucked by the fan can be
eecvely avoided, thus greatly improving the
reliability of the machine.
Excellent welding performance, rich funcon
integraon, high eciency, small size, lightweight,
and many other features make it very convenient
for both professional and non-professional welders
to put into use in both industrial applicaons and
outdoor applicaons and meet a wide range of
welding requirements.
Advanced IGBT inverter technology
The inverter frequency is 20 KHz which signicantly
reduces the loss of copper and iron, improves the
overall eciency and has a signicant energy saving
eect.

Automac protecon
The machine has excellent protecon funcons,
and there is a corresponding code when protecon
is enabled.
The machine integrates under-voltage and
overvoltage protecon. When the input mains
voltage is unstable and the voltage is too high or
too low, the welder protecon disables output and
prevents damage to the welder.
Overheang protecon: Due to high ambient
temperature or overloaded use, the temperature
of the internal components is too high the
protecon system prevents damage to the welder
due to high temperature.
Overcurrent protecon: When the welder exceeds
the design rated output, the welder enables
protecon to prevent damage to the welder.
Good product consistency and stable performance
This machine adopts intelligent digital control,
which is insensive to changes of component
parameters. The changes of component
parameters will not aect the performance of the
welder. It is insensive to changes in the
temperature and humidity of the environment.
Therefore, the consistency and stability of the
digital control welders are much beer than those
of the tradional welders.
Easy to use interface
Using the internaonally accepted graphical
language interface, the main human-machine
interface is simple, intuive and easy to
understand.
The operaon panel layout is convenient for
various user operaons.
High quality manual welding can be achieved
Excellent control algorithm signicantly improves
manual welding performance: Easier arc striking,
stable welding current, minimal spaer, non-sck,
good weld formaon, automac adaptaon to
changes in the length or cross-secon of the
welding cables, excellent quality in size
specicaons.
TIG welding of high requirements can be achieved
The improved digital constant current regulaon
technology ensures the low noise and high stability
of the arc in the full specicaon. In addion, the
sophiscated and mature control algorithm
provides a convenient and praccal method for the
user to freely control the current form. The
machine oers four classical TIG arc operaon
modes including 2 T, 4 T, cycle and spot welding
which provide a good way for users to realize the
special process requirements.
