1.
Position the welder in TIG LIFT and TIG HF mode.
2.
Fit the required electrode and nozzle to the electrode holder (Check the pro-
trusion and state of the electrode tip).
3.
Connect the ground cable quick connection to the positive (+) receptacle
and the clamp near the welding zone.
4.
Connect the torch power cable connector to the negative receptacle. (-) .
5.
Connect the gas hose to the regulator located on the gas cylinder.
6.
Regulate the welding mode and the desired parameters (Section 5.0) .
7.
Open the gas valve on the torch.
8.
Connection of relay command.
When relay command is required connect the relay to the socket on the
front panel. In this position regulation can be fractioned through the power
gauge.
9.
Turn ON the power source.

FUNCTION KEYS.
If you press for at least a second the function keys
On the panel as represented by the symbol.
It is possible to select the desired welding functions. With each function key
pressed you are selecting a welding function.
IMPORTANTE: VERTICAL FUNCTION KEYS DO NOT WORK DURING THE WELD-
ING STAGE.
5.1.1 Covered Electrode Welding MMA.
By pressing the function key 4 and taking the luminous indicator on symbol 1 -
Fig. 1 page 3) you can select the mode of electrode welding.
5.1.2 TIG DC HF Welding.
By pressing the function key 4- Fig. 1 page 3) you can select the mode of TIG
welding with high-voltage start until the luminous indicator reaches the position
on symbol 2- Fig. 1 page 3) , If you press the torch button you will get a high-volt-
age discharge that allows the arc fusing.
5.1.3 TIG DC Welding with Lift Start
By pressing the function key 4- Fig. 1 page 3) you can select the mode of TIG
welding with lift start until the luminous indicator reaches the position on symbol
3- Fig. 1 page 3) .
In this mode the arc fusing occurs with the following sequence:
a.
If the electrode points to the welding piece it provokes the short-circuit
between the piece and the electrode.
b.
Pressing the torch key the pre gas is set. The end of the pre gas is indicated
by a long BEEP.
If that operation is carried out starting from the post gas you get the long
BEEP immediately as soon as you press the torch key.
c.
During the BEEP it is possible to lift the electrode from the piece provoking
the arc fuse.
5.1.4 Two Times Welding.
Active only in TIG mode.
By pressing the function key 8- Fig. 1 page 3) you can position the luminous indi-
cator on symbol 5- Fig. 1 page 3) . In this mode you press the torch button to
prime the welding current and it should be pressed whilst welding.
