Safty Precaution
Generally Safety Precaution
Ensure to follow precautions specified in this manual, or else, an accident may happen.
The design and construction of input power supply, selection of installation site and use
of high pressure gas shall be performed according to the relevant standards and rules.
Irrelevant personnel are not allowed to enter the welding workplace. Only the qualified
personnel can install, overhaul, maintain and operate the welding machine.
Qualified staff is needed for installation, maintenance and use.
Make sure the welding machine is not used for other purposes except welding (such as
charging, heating and pipeline unfreezing, etc).
If the ground is uneven, please avoid dumping welding machine.
Avoid electrical shock or burn

- 4 -
Touching electric parts is forbidden.
Ensure to invite professional electrician to ground the welding machine with copper
conductor with specific cross section.
Ensure to invite professional electrician to connect power source in welding machine
with copper conductor with specific cross section. The insulating sheath cannot be
damaged.
Ensure to insulate the body and base metal when working in the wet and restricted area.
Please use safety net when working at heights.
Please close the input power when not in use.
Avoid welding fume and gas damaging human body
Ensure to use specified exhaust equipment to avoid gas poisoning and suffocation.
The protective gas will be deposited around the container bottom to cause suffocation.
Pay attention to the ventilation.
Avoid welding arc, splash and welding slag damaging human body
Ensure to wear protective glasses with enough overshadow. The arc will result in ocular
inflammation and the welding splash and slag will burn eyes.
Ensure to use protective supplies for welding, such as leather protective gloves, caftan,
cap, welding spats and apron to avoid welding arc light, welding splash and slag
burning skin.
Avoid fire, explosion and fracture and other accidents
The welding place cannot have the combustibles because splash and hot weld joint will
result in fire.
The cables and base metal must be connected firmly, or else, it may be heat to result in
fire.
Must not weld in the combustible gas or container with the combustibles, or else, it may
result in explosion.

- 5 -
Ensure to prepare fire extinguisher just in case.
To prevent the rotating moving parts wounding
Must not make fingers, hair and clothes close to the cooling fan and wire feed roll and
other rotating parts.
When feeding wire, must not make the welding gun end close to eyes, face and body to
avoid wire damaging person.
Avoid falling gas cylinder and breaking gas regulator
The gas cylinder shall be fixed reliably, or else it may dump to result in human injury.
Must not put gas cylinder in a place with high temperature or sunshine.
When opening gas cylinder valve, must not make face close to the gas outlet, or else
high-pressure gas may damage person.
Ensure to use gas regulator provided by the company and follow the use regulations.
Prevent the movement of welding
Must not stand under the welding machine and motion direction when moving welding
machine with fork lift truck or crane, or else, the welding machine may fall to cause
injury.
The rope sling shall bear enough pull force and cannot be broken when suspending. The
angle between rope sling and hook shall be no more than 30°.

Precautions of electromagnetic compatibility
1. Overview
Welding brings electromagnetic interference.
Minimize the interference emission of arc welding equipment with proper installation way
and correct application method.
The products described in the manual belong to Class A equipment (all occasions except
residential area powered by public electrical power system).
Warning: Class A equipment is not applicable to residential area powered by public
electrical power system. It is difficult to guarantee electromagnetic compatibility because of
conduction and radiated interference.
2. Advice of environment assessment
Before installing the arc welding equipment, the user shall evaluate the potential
electromagnetic disturbance of the surrounding. The considerations are as follows:
Check surrounding of arc welding equipment for other power cables, control cables, signals
and telephone wire.
Check for broadcasting and television launching and receiving equipment;
Check for computer and other controllers;
Check for high security level equipment, such as industrial protective equipment;
Consider the health of surrounding staffs, such as staffs with hearing aid and cardiac
pacemaker;
Check for calibrating or detection equipment;
Pay attention to immunity to interference of other equipment. The user shall make sure that
the surround equipment can be compatible. The additional protective measures may be
required;
Welding or other activity time.
The environmental range is decided based on the building structure and possible activities.
This range may exceed the boundary of building.
3. Method of reducing radiation emission
Public power supply system

- 7 -
The arc welding equipment shall be connected into public power supply system with the
method recommended by the manufacturer. In case of interference, please take addition
preventive measures, such as connecting filter with public power supply system. Ensure to
consider power able shielding for fixed arc welding equipment. The power cables can be
shielded with the metal pipe or other equivalent methods. Ensure to keep electrical continuity for
shielding.
Maintenance of arc welding equipment
Ensure to perform routine maintenance for arc welding equipment according to the method
recommended by the manufacturer. When welding equipment runs, all equipment inlets,
auxiliary doors and panels shall be closed and tightened appropriately. The arc welding
equipment cannot be changed in any form, unless the relevant change and adjustment are
allowed in the manual. The spark gap of arc initiation device and arc stabilizing device shall be
adjusted and serviced according to the suggestion of manufacturer.
Welding cable
The welding cable shall be short as much as possible and close to each other. Moreover,
welding cable shall be next to or close to ground cable.
Equipotential lap
Pay attention to lapping of metal objects in the surrounding. The lapping of metal objects
and workpiece will increase job hazard. When the operator touches these metal objects and
electrode, he may suffer from electrical shock. The operator shall be insulated from these metal
objects.
Workpiece earthing
The workpiece may be not provided with earthing because of electrical safety or workpiece
position, such as hull or building steel frame. When earthing is available for workpiece, radiation
emission may be reduced.But it is not always the case. Therefore, we must prevent the increased
risk of electric shock of users caused by the workpiece earthing or the damage of other electric
equipment. When necessary, some workpiece should be directly earthed, but directly grounding
is not allowed in some countries, user can achieve this effect only by selecting the appropriate
capacitor according to the regulations of the host countries.
Shielding

- 8 -
The shielding of surrounding equipment and other cables can reduce the electromagnetic
interference. The whole welding area can be shielded for special applications.

Brief description of the principle
The schematic diagram of the TIG series welding machine is show figure 2：
（Figure 2）Welding machine schematic
The welding machine adopts IGBT high frequency inverter technology, power frequency
220V or 380V power input，direct rectification and then sent to the inverter composed of IGBT
and other components to become high frequency alternating current, high frequency alternating
current obtained after inverter is passed through high frequency transformer after the
step-down,high frequency rectifier rectifies and filters, the output is suitable for the DC current
of the welding. Through this process, the dynamic response of the welder is improved, the
volume and weight of the transformer and the reactor are reduced, and the efficiency of the
whole machine is improved.
The design of the control circuit enables the welder to always achieve good welding
process performance when external conditions change(such as grid voltage fluctuations and
different output cable lengths).It is easy to arc,the are is stable,the weld is well formed,and the
welding current can be continuously adjusted.
