In the ending of the 4T function the
"china logic"
downslope is started by pressing the torch
switch. The downslope is on while the
switch is pressed, welding current is cut-off
when the switch is released. If it is pressed
for a longer time than the downslope, then
the current remains on the end current level
(see J06).
