lamp closest to this switch will light up, indicating the power source is ready for welding. The
equipment is returned to the position which it last carried out before the main switch was turned
to zero position.
Always start and switch off the machine with the main switch, never use the mains
plug as a switch.
2.12. OPERATION OF COOLING UNIT, KWU10

light-up for a moment. The unit is now ready for welding and will automatically return back to it
previous position, before the power was cut off.
Basic settings and displays (2, 3, 4, 5)
The wire feed speed is set via potentiometer No. 2, the value of which is shown on display No. 4.
The welding voltage is set via potentiometer No. 3, the value of which is shown on display No. 5.
During welding, display No. 4 shows the actual welding current value and display No. 5 shows
the welding voltage.
When MIG dynamics adjustment is activated via button No. 7, the MIG dynamics value is adjusted
through potentiometer No. 3 (see ‘Adjustment of MIG dynamics’).
When the adjustment of SETUP parameters has been confirmed with one long press on button
No. 6, the adjustable parameter is selected via potentiometer No. 2, the name of which is shown
