. The second stroke
means to release the torch button, the machine will start welding with the main

. The third stroke means to
press the torch button, the machine will start welding with the end current
ECu
after the ramp-down time
tdo
. The fourth stroke means to release the torch
button, the machine stops the welding process.
BILEVEL bCu ≠ 100 %
The difference of the BILEVELU compared to the classical steps is in the second
stroke, when by quickly pressing and releasing the torch button the machine
switches between the two set main welding currents.
