6 FUNCTION EXPLANATIONS
6.1 CA, constant welding current
The wire feed is controlled by the power source so that a constant welding current
can be achieved.
− Constant current value can be selected in the main menu.
6.2 CW, constant wire feed
The welding current is a result of the selected wire feed speed.
− Constant wire feed can be selected in the main menu.
