(11)
With a multi meter measure the input voltage is within the fluctuation range;
(12)
The power ground is well grounded.
NOTE:
Secure the gas cylinder in an upright position by chaining them to a stationary support to
prevent falling or tipping.
3.4.2 Operation for TIG Welding
(1) According to the above method to install is correct, turn the power switch to the “ON”
position, the power L.E.D. light should illuminate, the fan comes on, the device work
properly.
(2) Set the welding mode button to ‘Lift TIG’ or ‘HF TIG’.
(3) Set the welding parameters as required using the parameters control knob (following the
instructions in the previous section).
(4) The tungsten must be ground to a blunt point in order to achieve optimum welding results.
It is critical to grind the tungsten electrode in the direction the grinding wheel is turning.
(5) Install the tungsten with approximately 3mm to 7mm sticking out from the gas cup, ensuring
you have correct sized collet.
(6) Tighten the back cap.
(7) Commence welding. If necessary, readjust the parameters control knob to obtain the welding
condition re-quired.
(8) After completion of welding the Power Source should be left turned ON for 2 to 3 minutes.
This allows the fan to run and cool the internal components.
(9) Switch the ON/OFF Switch (located on the rear panel) to the OFF.
3.4.3 Remote current control
TIG series of welding machines can accept remote current control from a potentiometer/ analogue
signal or a digital up/down button signal. Potentiometer remote control will change the current
from the 5A minimum to the maximum set using the machine current control .Using an up/ down
button remote signal, the current may be increased or decreased in 1A increments, or ‘scrolls’ up
to 30A at a time if the button is held down. This is very useful for precision work.
