About your AlphaTig 200X
This welder adopts rectifiers designed with advanced inverter technology. The introduction of
inverter TIG welders derives from inverter power theory and devices. The inverter TIG welding
power uses high-power IGBTs to turn the working frequency of 50/60Hz to high frequency
(20KHz or higher). Then voltage is reduced and current is regulated. A powerful DC power
source can be produced by using the pulse width modulation (PWM) technology. The size and
weight of inverter welders are reduced remarkably, while the efficiency is increased by 30%
compared to older styled transformer based welders.
This product is a multi-purpose unit composed of DC pulse TIG welder and AC pulse TIG
welder, and DC Stick welder (MMA).
This welder allows you the versatility of welding various
types of metal including aluminum.
Warning!
This unit has a High Frequency start. This can interfere with some sensitive electronic
components so care should be taken when in close proximity to such devises.

Setup Instructions
The welder is designed with a power voltage compensation. When power voltage fluctuates
within a range of 15% of rated voltage, it will continue to operate.
If a longer cable is used, we suggest using cable with a greater cross section in order to reduce
line loss voltage.
PLEASE NOTE:
This Welder is designed to operate on Single Phase 110 and 220 Volt power sources. (110v 120v
220v 240v) with a plus or minus variant of 15%
1. Make sure that the vent of the welder is not covered or plugged to ensure the cooling fans
can operate to their full potential.
2. Please ensure all fittings and connections from argon bottle to welder are secured
correctly to prevent leaking.
3. When using a generator the unit should be grounded reliably with a grounding rod driven
into the ground.
4. The Ground Clamp dinse connector is inserted into the work port on the welder and is
turned clockwise to secure. The ground clamp is connected to a clean surface as close as
possible to the welding operation to ensure a good ground.
5. Install the TIG torch copper nut connection (place supplied plastic sleeve on nut
connection) from the torch cable connection to the TIG port, and tighten clockwise.
6. When the pedal switch is used connect the 5 pin plug of the pedal switch to the control
outlet socket on the panel face.
7. For stick operation (MMA), select stick function on the TIG/MMA switch, make sure the
Torch/Pedal switch is in the torch position.
Connect the stick electrode holder to the
negative port (-) and the ground dinse is connected to the positive port (+), these can be
reversed for Stick function for running electrode positive output.
8. Please note the diagram shows the whip in the electrode negative output.

Operating Instructions
DC TIG welding
1. Turn the power switch ON, this is located on the back of the unit, the digital current meter and the
cooling fans will turn on.
2. Open the valve on the gas cylinder and regulate the flow meter to the required value ( 15 to 20 cfh).
3. If the AC/DC switch is on DC mode, and in TIG function, welding such metals as stainless steel,
iron and copper is possible. When in AC mode aluminum welding is possible
4. When torch/pedal switch is in the torch position the arc will be controlled by the torch switch.
When the switch is in the pedal position the arc will be controlled by the pedal.
5. When the pulse switch is in the on position, you will need to set the pulse frequency for desired effect.
6. The pulse amps are a percentage of the main amps and this is to be set to what the required amps are
for the type of material being welded.
- 8 -
7. When you press the control button on the torch this will activate the solenoid valve and the high
frequency in the machine, a sound will be heard with the argon gas flowing through the torch. If
switched to pedal operation the pedal activates the flow and high frequency start.
8. The tungsten electrode of the welding torch is 2-4 mm from the work piece.
9. Using the Post flow control will protect the weld while it cools down by continuing the gas flow after
the arc stops.
10. When 2T/4T switch is in the 2T position only the main amps will operate along with the post flow. In
4T position arc start amps and end amps will work. Do not use 4T function with the foot pedal.
11. When in 4T mode you press and release the switch an arc will start and continue to run until you press
and release the switch again.
AC TIG welding
1. If AC/DC switch is in AC mode, this process will weld aluminum and magnesium. All other
metals require DC mode.
2. The AC balance (cleaning action) is used for oxidized aluminum. Care must be taken in
choosing the correct tungsten size, as too much cleaning action can overheat the tungsten and
melt it.
3. The AC frequency mode can alter the width of the arc and can create a narrow or wider bead
depending on the setting (125Hz is a common setting). Having a higher frequency can be of
help when working with thinner aluminum as it creates a smaller weld bead and using less
gives a softer wider bead.
DC STICK welding (SMAW)
1. For stick operation (MMA), select stick function on the TIG/MMA switch. Connect the stick
electrode holder to the negative port (-) and the ground dinse is connected to the positive port (+),
these can be reversed with the electrode holder in the positive port (+). The diagram shows
electrode negative, this gives a softer flowing bead for most rods.
Warning:
Inserting or pulling out any cable wire or plug while power is on will be hazardous
and will damage the welder.

Routine maintenance
Warning:
All the maintenance/service must be completed with the unit totally disconnected
from any power source.
Make sure the unit is not plugged into any electrical source before
removing the cover.
1 Dust should be removed with dry and clean compressed air regularly. If the welder is used in
a heavily polluted environment with smoke and polluted air, dust must be removed from the
welder each month.
2 The pressure of compressed air should be kept low so that damage is not done to the smaller
components in the welder.
3 Regularly check the connection of the electrical cord in the welder and make sure all other
connections are secured.
4 Welder needs to be stored and used away from water, dirt or dust.
Precautions
Warning
Opening the unit and exposing internal components that carry high voltage may lead to hazards
and any direct or indirect contact could result in electrical shock.
If within the warranty period the user carries out an unauthorized repair or alteration of the
welder, warranty can be voided. Warranty is for the original purchaser and is non transferable.
Preventative Measures
1. Environment
1)Welding operation should be carried out in a relatively dry environment with air humidity
less than 90%.
2)Ambient temperature should be kept between -10C ~40C.
Avoid spills of water or liquid in the welder
- 11 -
3)Welding in the dusty environment should be avoided.
4)TIG welding operation in an environment with strong winds or airflow should be avoided.
2. Essentials for safety
This welder has been equipped with over-voltage, over-current and overheat protection
circuits. When the grid voltage, output current and machine temperature surpass the set
standards, the machine will stop automatically. But excessive use (for example, when the
voltage is too high) can still lead to the failure of the welder.
Good ventilation!
The vents on the welder must be kept clear of all obstructions to allow for good airflow
through the unit. Keep at least 12 inches clear around the unit.
No overload!
Operators should remember that maximum welding amps relative to the duty cycle be
observed at all times and welding amps should never exceed the maximum duty cycle.
Over-cycling will shorten the life of the welder.
No over-voltage!
Power voltage is shown in the main performance parameter table. In general, the voltage
auto-compensation circuit in the welder will ensure the welding current remain within the
permissible range. If power voltage surpasses the permissible value, the welder will suffer
damage. Operators need to be aware of this and take preventative measures.
On the back of the welder there is a grounding screw with a grounding mark. The shell of the
welder should be grounded securely with a grounding rod driven into the ground when using
a with a clean power generator. Only a clean ‘Auto Voltage Regulated’ generator with a clean
sine wave is recommended for this welder.
If the welding machine exceeds the standard duty cycle, it will go into a protective state and
shut down, which indicates it has exceeded the duty cycle. Excessive heating triggers the
temperature control switch and shuts he welding process off. Under such circumstances do
not turn off the power, let the cooling fan continue running to cool down the unit. When the
temperature drops to the standard range, turn the welder off and turn it back on to continue
welding.
