• TIG AC - Pulsed
The Pulse function is available in TIG AC - Easy and TIG AC - Standard. The pulse frequency is adjustable from 0.1 Hz to 10 Hz.
TIG SPOT DC or AC
The " SPOT" mode allows the pre-assembly of parts by tacking. The tacking time adjustment allows a better reproducibility and the realisation of
non-oxidised tack. As default, when the " SPOT " mode is selected, the start and the end of the welding is done at the trigger. However, the " F(Hz) "
button and the main encoder allow the user to refine this time. The time in this "SPOT" tacking mode is adjustable by 0.1 sec. at 60 sec. in steps of
0.1 sec. The ignition is then done with the trigger. To return to an undefined spot time, simply select "0.0s".
JOBS MANAGEMENT
The current settings are automatically saved and loaded at start up. In addition to the current settings, it is possible to save and recall so-called "JOB"
configurations. The " JOB " button is used to save, recall or delete a configuration. 50 Jobs can be stored per welding process.
• Job Recall
- Apart from not being in the welding process, the recall of a job does not require any particular initial condition,
- Press the " JOB " button briefly (not more than 2 sec.),
- " OUT " appears on the HMI display,
- With the incremental encoder, select a job number. Only the numbers associated with existing jobs appear on the display If no job is stored, the
HMI displays "- - - -".
- Once the job number has been selected, press the "JOB" button to confirm the configuration. The job number then flickers on the display, indicating
that the job has been loaded. The number continues to flicker until another parameter is changed or until the torch trigger is pressed to start the
welding cycle.
• Job deletion
- Press the "JOB" button briefly (not more than 2 sec.),
- "OUT" appears on the HMI display,
- With the incremental encoder, select a job number. Only numbers associated with existing jobs can be displayed,
- Press successively 3 times on the " JOB " button. The selected job is now deleted and the power source displays the welding current again.
• Job creation
- Adjust all desired welding parameters,
- Press and hold the " JOB " button for more than 3 seconds,
- The display shows "IN",
- Select a job number using the incremental encoder. Only numbers that are not already assigned to a previously saved job can be selected and are
shown on the display,
- Once the job number has been chosen, press the "JOB" button to validate and save it under the selected number,
- The job number then remains displayed, indicating that the save action has been completed. The number continues to be displayed until another
button or the torch trigger is activated.
Note: If all numbers are already assigned to saved jobs, the HMI displays "Full".
Precisions for a job reminder in TIG AC: The special feature of a job reminder in TIG AC is the display of the parameters related to the "AC" functions.
When a job configuring the station in "AC" is called up, the HMI then displays successively the values of the welding current (in A), the balance (in %)
and the frequency (in Hz) following a repetitive cycle. This cycle lasts until the torch trigger is pulled to start a welding cycle.
