SAFETY PRECAUTIONS –READ BEFORE USING
These general safety norms cover both arc welding machines and plasma cutting machines unless
otherwise noted.
The equipment must only be used for the purpose it was designed for. Using it in any other way could
result in damage or injury and in breach of the safety rules. Only suitably trained and competent persons
should use the equipment. Operators should respect the safety of other persons.
Prevention against electric shock
The equipment should be installed by a qualified person and in accordance with current standards
in operation. It is the user’s responsibility to ensure that the equipment is connected to a suitable
power supply. Consult with your utility supplier if required.
If earth grounding of the work piece is required, ground it directly with a separate cable.
Do not use the equipment with the covers removed.
Do not touch live electrical parts or parts which are electrically charged.
Turn off all equipment when not in use.
Cables (both primary supply and welding) should be regularly checked for damage and
overheating. Do not use worn, damaged, under sized or poorly jointed cables.
Ensure that you wear the correct protective clothing, gloves, head and eye protection.
Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent
any physical contact with the work ground.
Never touch the electrode if you are in contact with the work ground, or another electrode from a
different machine.
Do not wrap cables over your body.
Ensure that you take additional safety precautions when you are welding in electrically hazardous
conditions such as damp environments, wearing wet clothing, and metal structures. Try to avoid
welding in cramped or restricted positions.
Ensure that the equipment is well maintained. Repair or replace damaged or defective parts
immediately. Carry out any regular maintenance in accordance with the manufacturer’s
instructions.
Safety against fumes and welding gases
Locate the equipment in a well-ventilated position.
Keep your head out of the fumes. Do not breathe the fumes.
Ensure the welding zone is in a well-ventilated area. If this is not possible provision should be
made for suitable fume extraction.
If ventilation is poor, wear an approved respirator. Read and understand the Material Safety Data
Sheets (MSDS’s) and the manufacturer’s instructions for metals, consumable, coatings, cleaners,
and de-greasers.
Do not weld in locations near any de-greasing, cleaning, or spraying operations. Be aware that
heat and rays of the arc can react with vapours to form highly toxic and irritating gases.
Do not weld on coated metals, unless the coating is removed from the weld area, the area is well
ventilated, and while wearing an air-supplied respirator. The coatings on many metals can give off
toxic fumes if welded.

Prevention against burns and radiation
Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared)
rays that can burn eyes and skin.
Wear an approved welding helmet fitted with a proper shade of filter lens to protect your face
and eyes when welding or watching
Wear approved safety glasses with side shields under your helmet.
Never use broken or faulty welding helmets.
Always ensure there are adequate protective screens or barriers to protect others from flash,
glare and sparks from the welding area. Ensure that there are adequate warnings that welding or
cutting is taking place.
Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot work
pieces, and hot equipment can cause fires and burns
Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode.
Accidental contact of electrode to metal objects can cause arcs, explosion, overheating, or fire.
Check and be sure the area is safe and clear of inflammable material before carrying out any
welding.
Protection against noise
Some welding and cutting operations may produce noise.
Wear safety ear protection to protect your hearing.
Protection from moving parts
When the machine is in operation, keep away from moving parts such as motors and fans. Moving
parts, such as the fan, may cut fingers and hands and snag garments.

Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of pacemakers or
electronically controlled medical equipment.
Wearers of vital electronic equipment should consult their physician before beginning any arc
welding, cutting, gouging or spot welding operations.
Do not go near welding equipment with any sensitive electronic equipment as the magnetic fields
may cause damage.
RF Declaration
Equipment that complies with directive 2004/108/EC concerning electromagnetic compatibility (EMC) and
the technical requirements of EN60974-10 is designed for use in industrial buildings and not those for
domestic use where electricity is provided via the low voltage public distribution system. Difficulties may
arise in assuring class A electromagnetic compatibility for systems installed in domestic locations due to
conducted and radiated emissions.
In the case of electromagnetic problems, it is the responsibility of the user to resolve the situation. It may
be necessary to shield the equipment and fit suitable filters on the mains supply.
LF Declaration
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 affect the quality of power provided by the network. Consequently, connection restrictions or
maximum impedance requirements permitted by the network at the public network connection point
must be applied to these systems.
In this case the installer or the user is responsible for ensuring the equipment can be connected,
consulting 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 separating components according to the type of
materials.
Do not dispose of the equipment with normal waste. The European Directive 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 compatible recycling facility.
Handling of Compressed gas cylinders and regulators
All cylinders and pressure regulators used in welding operations 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

EMF Information
Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields Welding
current, as it flows through welding cables, will cause electro-magnetic fields. There has been and still is
some concern about such fields, However, after examining more than 500 studies spanning 17 years of
research, a special blue ribbon committee of the National Research Council concluded that: "The body
of evidence, in the committees judgment, has not demonstrated that exposure to power-frequency
electric and magnetic fields is a human-health hazard." However studies are still going forth and evidence
continues to be examined. Until the final conclusions of the research are reached, you may wish to
minimize your exposure to electromagnetic fields when welding or cutting.
To reduce magnetic fields in the workplace, use the following procedures:
Keep cables close together by twisting or taping them.
Arrange cables to one side and away from the operator.
Do not coil or drape cables around your body.
Keep welding power source and cables as far away from operator as practical.
Connect work clamp to work piece as close to the weld as possible.

1.2 Introduction
The TitanTig 200 DC Pulse Pro welding machine adopts the latest pulse width modulation (PWM)
technology and insulated gate bipolar transistor (IGBT) power module, which can change work frequency
to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet
medium frequency transformer. Thus, it is characterized with portable, small size, light weight, low
consumption and etc.
The parameters of TitanTig 200 DC Pulse Pro on the front panel all can be adjusted continuously and
steplessly, such as start current, crater arc current, welding current, base current, duty ratio, upslope time,
downslope time, pre-gas, post-gas, pulse frequency, hot start, arc force and arc length etc. When welding,
it takes high frequency and high voltage for arc igniting to ensure the success ratio of igniting arc..
The TitanTig 200 DC Pulse welding machine is suitable for all positions welding for various plates made of
stainless steel, carbon steel, alloyed steel, titanium, magnesium, cuprum, etc, which is also applied to pipe
installment, mould mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and
common manufacture.

DC MMA
DC TIG
DC Pulse TIG
DC MMA, polarity connection can be chosen according to different electrodes.
DC TIG, DCEP is used normally (workpiece connected to positive polarity, while torch connected to
negative polarity). This connection has many characters, such as stable welding arc, low tungsten pole loss,
more welding current, narrow and deep weld;
DC Pulsed TIG has the following characters: 1) Pulse heating. Metal in Molten pool has short time on high
temperature status and freezes quickly, which can reduce the possibility to produce hot crack of the
materials with thermal sensitivity. 2) The workpiece gets little heat. Arc energy is focused. Be suitable for
thin sheet and super thin sheet welding. 3) Exactly control heat input and the size of the molten pool. The
depth of penetration is even. Be suitable for welding by one side and forming by two sides and all position
welding for pipe. 4) High frequency arc can make metal for microlite fabric, eliminate blowhole and
improve the mechanical performance of the joint. 5) High frequency arc is suitable for high welding speed
to improve the productivity.

Working Principle
The working principle of TitanTig 200 DC Pulse Pro welding machines is shown as the following figure.
Single phases work frequency AC 220V (50 Hz) is rectified into DC (about 312V), then is converted to
medium frequency AC (about 40KHz) by inverter device (IGBT), after reducing voltage by medium
transformer (the main transformer) and rectifying by medium frequency rectifier (fast recovery diode),
and is outputted by inductance filtering. The circuit adopts current feedback control technology to insure
current output stably. Meanwhile, the welding current parameter can be adjusted continuously and
steplessly to meet with the requirements of welding craft.

and lead to a minimum of 32A if
sustained usage at maximum
amperage is desired.
▲WARNING
With the 15A plug supplied it is
recommended that the operator
does not exceed more than
180Amps, as use of higher
amperages over this amount may
lead to failure and overheating of
the 15A plug and circuit, which
may result in electrical supply
component damage and
ultimately electrical fires.
