Safety
In welding and cutting processes protective measures should be taken to
prevent injuries. For details refer to the safety protection guide for
operation that meet the manufacturers’ requirements for accident
prevention.
Electrical Shock
·Grounding devices should be installed according to the applicable standards.
·Do not make contact with live parts or welding with exposed skin or with wet gloves or
clothing.
·Make sure insulation exists between you and the ground and the work piece.
·Make sure that your operating position is in a safe state.
Smoke
·Inhalation of smoke should be avoided.
·In arc welding a ventilator or exhaust should be used to avoid inhalation of welding gas.
Arc light radiation
·Exposed skin should be covered when welding to avoid burns caused by exposure to the
welding arc. A suitable welding helmet and filter lens to protect your eyes must be worn to
avoid arc flash.
·Appropriate welding helmets or curtains should be used to protect spectators from injury.
Fire
·Welding spark may lead to fire. Please make sure no combustibles exist near the welding
area.
Noise
·Protect your ears by wearing hearing protection.
Warning
This unit requires proper grounding!!!

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.

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.
