Minilog
When torch switch is pressed gas flow starts. When you release the torch switch current goes through
upslope to Hot Start or Soft Start -current depending on adjustments and by pressing shortly again
to welding current. After another short press it goes to Minilog operation, and you can select from
two current levels: the welding current and the Minilog current. You can move from one to the
other by quickly pressing the torch switch. Press the torch switch for one second, release it and
current goes to downslope and tail arc. Arc is cut by short press of the switch.
4T-LOG
When torch switch is pressed current goes to search arc; after the switch is released current goes
to welding current within the upslope time. When the switch is pressed again, current goes to
downslope and then to the tail arc. Current stops when the switch is released.
Synergetic quick pulse
Press the PULSE button twice and the synergetic light turns on. Pulse parameters are calculated
automatically when average welding current is selected. Other pulse selections are not
necessary.
Long pulse
Long pulse method gives you the possibility to adjust all pulse parameters (pulsing frequency,
pulse ratio, pulse current and pause current). You can also adjust the welding current, in which case
you receive a new pulse current value. Pulse ratio and pause current percentage remain constant.
When you adjust the pulse ratio, pulse current or pause current, the new average welding current
value is shown on the display.
Spot welding function
The function can be used both in 2T and 4T mode. Enter the spot duration by pressing arrow button, and
when the led is lit you can choose the spot time needed by turning the pulse potentiometer.
TIG -Micro tack welding function (MicroTack™)
You can select the Micro Tack function with a long press of the SPOT arrow button. When this function is
activated, the machine automatically enables the DC- welding mode, 2T switch mode and contact ignition.
Also the upslope and downslope values are set to zero and SPOT led starts to blink. To inactivate the Micro
Tack you press briefly the same arrow button.
This function can be used with HF ignition and 4T mode. The duration of the spot weld can be adjusted by
pressing Quick Setup button and selecting a value in the range 1-200 ms. The Micro Tack welding current
can be adjusted with the control knob, when the welding current led is on.
3.2.3. Saving welding settings
ACX panel has 10 memory channels for user settings. The selections are made in the MEMORY
field. Not only welding parameters but also function selections can be saved in the memory. MMA
welding values can also be stored in memory channels. Proceed as follows:
1. Press MEMORY button and if the SET light starts blinking the channel is free. If a channel is
in use, the ON light will light up. Press again, and the SET light will be continuously lit.
2. Select memory channel by pressing CH button.
3. Select the parameters and press SAVE button.
4. Press MEMORY button twice. ON led is lit.
5. Start welding.
If the saved settings need to be adjusted the led has to be moved from ON to SET position in order
to select parameters. Press the SAVE button.
When the memory function is in OFF state (no lights on) it is also possible to save the currently used
panel parameters by pressing SET/SAVE, by choosing channel ja by pressing SET/SAVE again.
Channel is cleared if MEMORY and CH buttons are pressed simultaneously in SET mode.
