Safety instructions
Protect yourself against emerging radiation! Use only standardized protective glasses with the
appropriate protection level (9, 10, 11, 12, 13). The device may only be used with gloves, all
exposed skin areas must be covered by appropriate protective clothing. All persons involved
and the welder must be adequately protected.
Protection against electrical current: small welding machines can be operated with 230 V
mains. The relevant regulations of the professional associations must be observed when connecting! Work on the mains circuit may only be carried out by qualified electricians! Cables
must not be run over! Fuses must never be patched!
Protective earthing, zeroing, FI protection circuit of the welding circuit: Welding machines have
an open circuit voltage between 80 and 100 V, depending on the design and type of the machine. Damp surfaces, wet, sweaty work clothes and poorly insulated shoes are particularly
dangerous. Fully insulated electrode holders provide protection. AC devices should not be
used in confined spaces.
Protection against weld spatter is provided by sturdy high shoes! Pants without cuffs should
reach over the upper edge of the shoe! Keep work clothing free from oil, grease, solvents and
the like! Leather gloves and a leather apron must be used, possibly gaiters, and possibly head
protection.
Protection against gases and vapours: Welding produces gases, vapours, smoke and dust. If
these pollutants are inhaled in higher concentrations, they can be harmful to health!
◦ Caution, special danger caused by
▪ nitrous gases or nitrogen oxides (NO2, N2O4) in confined spaces with poor ventilation!
▪ lead vapour from paint containing lead!
▪ zinc vapour when welding galvanized components, which can lead to zinc fever!
▪ cadmium vapour from cadmium coatings, which, like zinc, are used as corrosion protection!
◦ Adequate protective measures:
▪ Adequate ventilation!
▪ Welding outdoors if possible!
▪ Use suction!
▪ Always put on a breathing mask or device!
▪ Apply paint after welding or remove before welding in the case of repairs!
The electrode welding device has protection class IP21S. Devices in this category are only
protected against dripping water falling vertically from above. They are not suitable for use in
the rain. Never use the device in a wet environment. Furthermore, this device is not suitable
for thawing frozen water pipes. Such use is expressly prohibited.

Use the carrying handle. Be sure to use the handle provided to lift the device.
Watch out for damage. Check the device for any damage before putting it into operation. If the
device shows defects, it must not be put into operation under any circumstances.
Do not use any pointed objects. Never insert pointed and/or metallic objects into the interior of
the device. Do not misuse. Use the device only for the purposes described in this operating
manual.
Check regularly. The use of this device can lead to wear and tear on certain parts. You should
therefore check the device regularly for any damage and defects.
Correct use of the power cord. Never pull the plug out of the socket by the power cord and
protect all cables from oil, sharp edges and high temperatures.
Use only original accessories. For your own safety, only use accessories and additional
devices that are expressly specified in the operating instructions or recommended by the manufacturer.
Risk of accidents due to electric shock
If no arc is burning, there is no-load voltage U 0 between the earth terminal and the electrode holder.
This voltage can be life-threatening if the welder touches the metal clamping jaws of the electrode
holder and the workpiece with bare hands. It is therefore essential to observe the following information:
Always wear protective gloves made of insulating material.
Always wear suitable clothing. Avoid clothing made of plastic and never weld with a bare
torso.
Wear solid, insulating footwear. Make sure that the soles are never nailed.
Never sit or lie down on metal without a pad made of insulating material.
Check the condition of the cables before each use. Do not use the device if the cables are
damaged.
Risk of accident due to lack of air
Significant amounts of smoke and gas are produced during welding. Make sure that smoke
and gases can always escape through a suitable opening. But never add oxygen. This increases the risk of fire.
Danger of accidents from the rays of the arc: The glaring light of the arc and the ultraviolet
rays released can damage the eyes. Always wear a suitable protective shield with standardized anti-glare glass to protect your eyes.
Risk of accident from spraying sparks: The spraying welding sparks can cause painful burns.
Therefore, it is essential to observe the following information:
◦ Always wear a leather apron and leather gloves.
◦ Wear suitable headgear when welding overhead.
◦ Let your pant legs fall over your shoes.
◦ Wear sturdy, insulating shoes.
Risk of accident due to slag particle splashes
The slag is hard and brittle after it has solidified. The slag hammer will then break it into sharp-edged
particles that can dangerously injure the eyes. You should therefore protect your eyes when removing
the slag with suitable protective goggles.

Risk of fire from spraying sparks
If the molten or glowing metal and slag particles fall on flammable substances, they can ignite and
cause a fire. Therefore, remove all flammable objects from your work area before starting welding
work. Pay particular attention to the following materials:
paper
rags
textiles
wood and wood fibres
rubber
plastic
petrol
oils
tar-like substances
paints and solvents
Risk of explosion
Both the welding sparks and the highly heated welding point itself can cause explosions. Therefore, do
not use the device in an explosive environment in which there are substances such as flammable liquids, gases and paint mist. – Also note:
Remove the electrode from the electrode clamps immediately after finishing your welding work
in order to avoid unwanted arcing.
When the welding machine is in operation, do not place the electrode tongs on the welding
machine itself or on any other electrical device.
Before finishing your welding work, do not touch the electrode itself or any other metal object
that is in contact with the electrode.
After finishing your work, let the device run for a few minutes before you disconnect it from the
power supply.
Description of the product
The TIG 180/200 devices are single process argon-arc welders.
Outer characteristics of this welding machine are
◦ continuous current and an arc drive controlling
◦ constant current characteristics: when arc voltage is normal, it guarantees that welding
current will not be changed with arc length. The current will become higher and higher with
arc voltage down-slope. When arc voltage is too low, it will lead to an arc length that will
return into normal range. When arc voltage is too low to support the arc, voltage will down
slope immediately in order to protect from splashing which is caused by a short circuit.
◦ continuous current: The welding current will not change arc length, so that the current is
very stabilizing .When electrode circuit is short, current will declined to 0 automatically in
order to protect tungsten and work piece.
This arc welding machine has characteristics as following:
◦ high quality
◦ stable arc
◦ molten bath easy to control
◦ no-load voltage is higher
◦ wide application range: suitable for high-altitude and outdoor work and inside or outside
mounting
◦ lightweight
◦ simple installation and operation
Caution: The user is not permitted to dismantle, rebuild or replace electrical components himself. Oth erwise the guarantee of the device will expire.

Installation
If you want to use a longer cable, please choose a cable with a larger cross-section to avoid voltage
drops. If the torch cable is too long, it may interfere with the operation of the arc and other functions of
the system. For this reason, we recommend that the user stick to the length recommended by the
manufacturer.
Connecting the input cable
Every welding machine has a power cable that must be connected to the respective voltage
according to the input voltage. If a single-phase 230 V DC power cord is negligently connected
to the 380 V AC power cord, the power switch will be set to the overvoltage protection position. Please turn off the power supply first, then connect the machine to a voltage of 220 V;
then turn it back on. The input voltage must be single-phase 230 V.
Make sure the power cord is securely connected to the power switch or plug and prevent oxid ation. Check whether the line voltage is within the wave range.
Connecting the output cable
When using argon arc welding devices, please connect them as described above. When using
impact mode, keep the following in mind: Each machine has a pair of movable plugs. The
cable of the welding handle is connected to the black movable plug; the other connection of
the earthing clamp is connected to the red movable plug. After that, they need to be tightened.
Make sure that the secondary cables (handle cables and ground cables) are securely connec ted to the movable connector.
Insert the mobile plug into the mobile socket and tighten it. Otherwise, the plug and socket will
be burned if, for example, the current is too high or the operating time is too long.
Pay attention to the electrode of the connection cable. There are two types of connection: positive connection and negative connection. The positive connection is when the workpiece is
connected to positive electricity and the torch handle is connected to a negative electrode; the
negative connection is when the workpiece is connected to negative electricity and the torch
handle is connected to a positive electrode.

Operation
Argon arc welding
Make sure that the power switch is “on” and the indicator is lit.
Open the valve of the argon bottle and adjust the volume of the flow meter.
The interaxial axial fan now starts to work. Press the burner control button to start the electro magnetic valve. The user can hear the sound of HF arcing and at the same time the argon begins to flow from the torch nozzle.
The arc thrust button is used to set the welding function, especially in a low current range,
which interacts with the welding current setting button. These can adjust the current of the arc
and are beyond the control of the welding current setting rotary knob. This allows the machine
to generate powerful energy and the pressure current can achieve an effect that can mimic the
rotation of a DC welding machine.
The distance from the welding electrode to the workpiece must be 2–4 mm. Then you have to
press the control button. When burning and hitting the arc, the noise of the HF arc is reduced.
The welding machine can now be operated.
Description of the strike mode
Open the power switch on the front control panel to activate the fan.
Make sure that the function switch is at the bottom.
Set the welding current according to the thickness of the workpiece.
Set the characteristic welding line with the drive button.
Note: Do not touch any cables or plugs while the machine is in operation, as this can result in damage
to the health of persons or damage to the machine.
Maintenance
Remove dust with dry and clean compressed air. If the welding machine is operated in an environment with polluted air or smoke, the machine must be de-dusted daily.
The pressure of the compressed air must be within a reasonable range to prevent damage to
small components of the machine parts inside the device.
Regularly check the intermediate circuit of the welding machine and make sure that the cable
circuit is correctly connected and that the plugs are firmly connected (especially connectors
and components). If any debris and loose parts are found, please sand them well and then
reattach them firmly.
Avoid getting water and steam into the machine. Should they penetrate, please dry the ma chine and then check the insulation of the machine again (also between the connectors and
the jacket and between the connectors and connections).
If the welding machine is not used for a long time, it must be packed up and stored in a dry
place.
