2: SUMMARY
Working principle:
The AWE-T1200 uses inverse arc welding power supplies and high-power devices to
convert 50/60Hz frequencies to high frequencies (e.g. 100KHz or higher), then lowers
voltage and regulates current, producing a powerful DC TIG welding power supply
through (PWM).
Due to the use of switching power supply, inverter technology, the weight volume
of the welding machine can be reduced, and the efficiency is increased by 30%.
AWE-T1200 can generate arc very easily, with advance gas delivery, delay
shutdown and welding current automatic attenuation, continuous time adjustable, pulse
frequency adjustable. It automatically controls arcing to improve welding stability ignorer
to get a beautiful welding surface.
AWE-T1200 can be used in stainless steel, alloy steel, carbon steel, copper and
other non-ferrous metals welding. The overall power conversion efficiency of the welder
is more than 85% in general.

3: MACHINE INSTALLATION
Safety warning:
Use original accessories to ensure proper operation of the welding machine
The power outlet needs to be well grounded, and if not confirmed, ground the shell
separately with a ground wire with a cut-off area of not less than 6mm (there is a
grounding screw on the back of the welder, on position ⑤)
Please use 220V single-phase AC power supply. If power supply is not stable please
use a stabilizer, if higher than 220v it may cause a damage to the machine.

BUTTON AND FUNCTION
MODE button: default on TIME mode, press to adjust W-TIME and TIME.
Press MODE button FREQ light will turn red, press to adjust FREQ and PWM
Both of the two modes can adjust pulse time and interval time on AUTO SPOT mode
SAVE button: AWE-T1200 can save 20 groups of settings. When parameters set to
right values press and hold SAVE button for 3 seconds, LED will turn to red, release
SAVE button you will see “CC” on W-TIME/FREQ screen and “00” on TIME/PWM
screen, press under TIME/PWM screen to choose a number, then press
SAVE button to save the settings on that group.

F. Press finger click button on welding gun to start welding.
EXAMPLE
EXPERIENCE:
Air inside the welding gun needs to be drained before welding begins to obtain a
clean welding spot.
The tungsten needle needs to be sharp.
For thin sheet welding the tungsten should close to the sheet, normally <1mm.
The first spot is important, when the first spot formed the next spot should close to
the first one.

Flat surface welding method:
Here mentioned flat surface include flat and arc surface. Welding arc
should heat the workpiece first, only after the workpiece melted then the welding
wire can transition to the workpiece to form qualified welding points. During
operation the tungsten needle distance from the workpiece should close than
tungsten needle distance from the wire. Tungsten needle position please refer to
the following diagram, keep “L” and “V” as smaller as you can (both <1.0mm).
Inner corner welding method:
We refer here to the angle is the angle between the two formed workpiece
is equal to or less than 90 degrees. Because of the characteristics of arc
discharge through the shortest path, the conventional welding method often can
not welding to the bottom corner.
The tungsten needle should be grinded very sharply
(< 20 degrees), and do not use welding wire, tungsten
needle direct close to the bottom (see the below picture).
Both sides of the metal were melted to the middle position
to form a solder joint. If it is necessary, need to increase the
welding current, until the middle form of a solder joint.

5: FAULT DIAGNOSIS AND ELIMINATION
QUESTIONS
REASONS
SOLUTIONS
WELDING WIRE MELTS
INTO BALL SHAPE,
FAILED TO MELT ON THE
WORKPIECE
1、Tungsten needle too close
to the wire and too far from the
workpiece
Put tungsten needle from wire about
0.3-1.0mm distance, at the same time
keep 0.2-0.7mm to the workpiece. do
not move the torch when step on the
foot pedal.
2、The power output is too
small
To increase the pulse current and
pulse time to increase the power
output.
3、Tungsten needle is not
sharp enough
Grind tungsten needle sharp
4、Welding wire not touch the
workpiece
Keep welding wire touch the
workpiece
WELDING SPOT IN BLACK
COLOR OR YELLOW
COLOR
1、Tungsten needle too long
outside the ceramic nozzle
Adjust the needle position to keep less
than 5mm outside the nozzle
2、Power output to big
Adjust the power output
3、The workpiece is dirty
Clean the workpiece surface
4、The argon air tank not open
or argon flow is too small
Check whether there is argon air going
outside when step on the foot pedal,
adjust the argon air flow value.
THERE IS ARC SOUND BUT
CAN NOT WELDING
1、Grounding line not connect
to the workpiece
Connect the grounding line to the
workpiece
2、The arc welding gun is too
far from the workpiece
Keep the right distance between
tungsten needle and work piece
