3.2.3. Saving welding settings (MTM)

MTM 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 twice and if the SET light starts blinking the channel is free. If
the channel is reserved the led will remain 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 and adjust settings if necessary.
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. It is also possible to save the currently used parame-
ters by pressing SET when the memory function is in OFF state (no lights on). Channel is cleared if
MEMORY and CH buttons are pressed simultaneously in SET mode.
