shielding gas, which flows from the shielding-gas nozzle, which is positioned
concentrically around the electrode.
3.3.18 The Special mode
3.3.18.1 General Description
The operating panel enables the complete overview of the important settings for
the both TIG and stick-electrode welding on the TIGER machine. In addition to
this the numerous special parameters and functions in the special mode can also
be set and altered according to the individual requirements.
These are:
A
–
The gas pre-flow time
B
–
The ignition energy
C
–
The start current
D
–
The up-slope time
E
–
The crater fill current
F
–
Dual Wave
H
–
Hot Start
I
–
Arc Force
S
–
Save programme
L
–
Load programme
The special mode is activated by turning the turn and set knob until the special
mode LED (Fig 3.1 and Fig 3.2, LED18) is illuminated, and then depressing the
turn and set knob for longer than 2 seconds. Once the mode is activated the
digital display show the letter assigned to the special parameter and the value
set. (e.g. “A2.4” means that the gas pre flow time (A) is set to 2.4 seconds). The
alteration of the parameters and their values is done by using the turn and set
knob as described on the following page:
The alteration of the parameters,
Turn the knob until the required parameter is displayed
Depress the knob to select the parameter, the letter on the digital display
starts to blink
Turn the knob until the required value is reached
Press the knob to save the value (enter)
Particular characteristics of the Special mode
The processor also controls the special mode, in that only those functions that
relate to the operating mode selected can be accessed and altered.
