1. General Safe Practices
Become trained and read the instructions before
working on the machine or welding or cutting. Read
and understand the Safety Data Sheets (SDSs) and
the manufacturer's instructions for adhesives,
coatings, cleaners, consumables, coolants, de-
greasers, fluxes, and metals.
Wear approved safety glasses with side shields under your welding helmet or face shield
and at all times in the work area.
Read and follow all labels and the Owner's Manual carefully before installing, operating, or
servicing unit. Read the safety information at the beginning of the manual and in each
section.
Wear a safety harness if working above floor level. Keep children away from all equipment
and processes.
Do not install or place machine on or over combustible surfaces.
Use GFCI protection when operating auxiliary equipment in damp or wet locations.
Use only genuine replacement parts from the manufacturer.
Perform installation, maintenance, and service according to the Owner's Manuals, industry
standards, and national, state, and local codes.
2. Arc Welding Hazards
Electric shock from welding electrode or wiring can kill.
Wear dry, hole-free insulating gloves and body protection. Do not touch electrode with
bare hand. Do not wear wet or damaged gloves.
Do not touch live electrical parts.
Do not use AC weld output in damp, wet, or confined spaces, or if there is a danger of
falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on unit. Do not use worn,
damaged, undersized, or repaired cables.
Additional safety precautions are required when any of the following electrically hazardous
conditions are present: in damp locations or while wearing wet clothing; on metal
structures such as floors, gratings, or scaffolds; when in cramped positions such as
sitting, kneeling, or lying; or when there is a high risk of unavoidable or accidental contact
with the workpiece or ground. For these conditions, use the following equipment in order
presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual (stick)
welder, or 3) an AC welder with reduced open-circuit voltage.
7

Protect yourself from electric shock by insulating yourself from work and ground. Use
non-flammable, dry insulating material if possible, or use dry rubber mats, dry wood or
plywood, or other dry insulating material big enough to cover your full area of contact with
the work or ground and watch for fire.
Disconnect input plug or power before working on machine. Do not make input
connections if color blind.
Frequently inspect input power cord and ground conductor for damage or bare wiring –
replace immediately if damaged – bare wiring can kill. Keep cords dry, free of oil and
grease, and protected from hot metal and sparks. Be sure input ground wire is properly
connected to a ground terminal in disconnect box or receptacle.
Properly install, ground, and operate all equipment according to its Owner's Manual and
national, state, and local codes.
Breathing welding fumes can be hazardous to your health.
Keep your head out of the fumes. Do not breathe the fumes. Use enough ventilation,
exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the
general area. The recommended way to determine adequate ventilation is to sample for the
composition and quantity of fumes and gases to which personnel are exposed.
Read and understand the Safety Data Sheets (SDSs) and the manufacturer's instructions
for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
Use enough forced ventilation or local exhaust (forced suction) at the arc to remove the
fumes from your breathing area.
Use a ventilating fan to remove fumes from the breathing zone and welding area.
If adequacy of ventilation or exhaust is uncertain, have your exposure measured and
compared to the Threshold Limit Values (TLV) in the Safety Data Sheet (SDS).
Welding can cause fire or explosion.
Do not weld near flammable material or where the atmosphere can contain flammable
dust, gas, or liquid vapors (such as gasoline). Move flammables at least 35 feet (11
meters) away or protect them with flame-proof covers (see NFPA 51B listed in Section.

4. Special Situations & Equipment
Confined spaces can be hazardous.
Confined spaces are areas which lack room for full movement and often lack ventilation, such as storage tanks, vats, tunnels,
boilers, pipes, hold of a ship, corners of a room, near a ceiling or floor corner, or in a pit. Gases can collect and form dangerous
concentrations.
Always open all covers, remove any hazardous or toxic materials, provide forced ventilation, and provide a means to turn off
power and gas from the inside.
Never work alone — have constant communication with someone outside who can quickly turn off power and gas, is trained in
rescue procedures, and is able to pull you out in case of emergency.
Do not use AC weld output in confined spaces.
Insulate yourself from work and ground using non-flammable, dry insulating material if possible, or use dry rubber mats, dry
wood or plywood, or other dry insulating material big enough to cover your full area of contact with the work or ground, and
watch for fire.
Always check and monitor the air quality in the space. Welding or cutting fumes and gases can displace air and lower the
oxygen level — use ventilation and, if needed, an air-supplied respirator. Be sure the breathing air is safe. The recommended
way to determine adequate ventilation is to sample for the composition and quantity of fumes and gases.
Always remember: All normal arc welding and cutting hazards are amplified in confined spaces. See ANSI Z49.1 listed in
Principal Safety Standards (Section 9).
Cylinders can explode if damaged.

Electric and magnetic fields (EMF) can affect Implanted Medical Devices.
Wearers of Pacemakers and other Implanted Medical Devices should keep away.
Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
Hot parts can burn.
Do not touch hot welded or cut parts with bare hand. If handling is needed, use proper tools and/or wear heavy, insulated
welding gloves to prevent burns.
Allow cooling period before handling parts or working on equipment.
Falling equipment can injure, and damage equipment.
Use lifting eye to lift unit only, NOT running gear, gas cylinders, trailer, or any other accessories. Use correct procedures and
equipment of adequate capacity to lift and support unit.
If using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit.
Do not place unit where it can easily tip over or fall.
Battery charging output and battery explosion can injure.
Sparks can cause battery gases to explode.
Do not smoke and keep matches and flames away from battery.
Wear a face shield or safety glasses when working near or on a battery.
Do not use welder or plasma cutter to charge batteries or jump start vehicles unless the unit has a battery charging feature
designed for this purpose.
5. EMF Information
Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc
welding (and allied processes including spot welding, gouging, plasma arc cutting, and induction heating operations) creates an
EMF field around the welding circuit. EMF fields can interfere with some medical implants, e.g. pacemakers. Protective
14

measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or conduct
individual risk assessment for welders. All welders should use the following procedures in order to minimize exposure to EMF
fields from the welding circuit:
1. Keep cables close together by twisting or taping them or using a cable cover.
2. Do not place your body between welding cables. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep head and trunk as far away from the equipment in the welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld whilst carrying the welding power source or wire feeder.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the device manufacturer be- fore performing or going near
arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If cleared by your doctor, then
following the above procedures is recommended.

As a rule of thumb, start with a shade that is too dark to see the weld or cut zone. Then go to a lighter shade which gives
sufficient view of the weld or cut zone without going below the minimum. In oxyfuel gas welding, cutting, or brazing where the
torch produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line in the visible light of
the (spectrum) operation.

PRODUCT DESCRIPTION
Congratulations on your purchase. Please take a few moments to completely read through this manual. Doing so will make
your welding experience much more pleasant and understandable. And remember, should you need, seek or desire further
understanding of welding principals and practices, the internet is your friend! Take advantage of today’s information highway.
The internet holds a wealth of information and knowledge. Enjoy!
This welder is an inverter based machine the utilizes the most advanced inverter technology. IGBT circuits along with PWM
technology along with the greatly reduced size and weight, enable this welder to not only be more efficient by 30%, but also as a
result of the electronic circuitry, enables this welding machine to afford the user far more and better range of settings for each
specific weld. The ACDCTIG200 also has a 40% duty cycle at full amperage which, explained another way, allows for a full four
minutes of uninterrupted continuous welding at full amperage within a ten minute period. Far more capable than any user
would dream of attempting.
The TIGACDC250GD is capable of welding with either AC or DC current. This allows the user to choose DC current welding for
carbon steel, stainless steel, copper and many other metals, while also being equipped with the ability to switch over to AC
welding used in welding aluminum and aluminum alloys. In addition to its advanced TIG welding functions, the TIGACDC250GD
is also a very good MMA / Stick welder.
This AC/DC TIG welder adopts our company’s exclusive High Frequency technology as well as a pure square wave output,
excellent arc force and a wide range of balance control for aluminum cleaning.
This AC/DC TIG welder also offers a feature not always found in this price range. That is a completely dedicated foot control
with no interim current control on the foot pedal. This design is a much sought after feature of advanced welders who dislike
greatly the idea of inadvertently changing amperage settings while readjusting the foot pedal with their feet while changing their
welding positions. This is no longer a concern with the Weldpro TIGACDC250GD since all amperage control settings are made
from the console on the machines face.
The TIGACDC250GD also has provisions on the back side for connecting an optional water cooler that must be used in
conjunction with optional water cooled tig torch set.
Thank you for purchasing our product. We are sure you will soon realize the great value and quality that went into the design
of this welder as well as all of the advanced features and functions.
