DTX-2200-3000 AC/DC
■ ELECTRODE DIAMETER
For TIG welding with HF ignition, it allows you to use the relevant key to set the diameter of the tungsten
electrode used, and/or to change it using the ENCODER knob, in order to achieve the best control of the
AC arc in a synergic manner.
WARNING: The electrode diameter CANNOT be selected when the welding machine is set for the SPECIAL
configuration.
■ WELDING MODE
The DTX welding machine offers 4 welding modes. Each time the button is pushed, the welding machine switches
to select the welding mode indicated by the LED that stays lit, in the following order:
L5 2 STROKES
L6 4 STROKES
L7 Bi-Level
L8 SPOT WELDING
L5 2 STROKES
When the torch button is pushed welding begins starting with the INITIAL CURRENT (if SLOPE UP is selected),
while when it is released welding ends when the FINAL CURRENT is reached (if SLOPE DOWN is set).
L5 4 STROKES
TIG welding takes place as follows:
• When the torch button is pushed welding begins at the INITIAL current.
• When the torch button is released the SLOPE UP process is carried out (if applicable) and the current returns to
the PRINCIPAL value I
1
.
• When the torch button is pushed the SLOPE DOWN process is carried out (if applicable) and the current returns
to the FINAL value.
• When the button is released the welding Bi-Level ends.
L7 Bi-Level
When this function has been activated, TIG welding takes place as follows:
• When the torch button is pushed welding begins at the INITIAL current.
• When the torch button is released the SLOPE UP process is carried out (if applicable) and the current returns to
the PRINCIPAL value I
1
.
• When the torch button is pressed and released within less than 1 second the welding current goes to the Bi-
Level value ( I
2
), and by repeating this operating you can move between the two current levels ( I
1
), ( I
2
) an
infinite number of times.
• When the torch button is pushed and held down (for longer than 1 second) you exit the cycle, the SLOPE DOWN
process is carried out (if applicable) and the current returns to the FINAL value. When the torch button is released
the welding cycle ends. This welding mode is especially indicated for welding profiles with different thickness,
where continuous current variation is required. Also, when welding aluminum, it allows you to have a higher initial
current, thereby facilitating pre-heating of the work piece
