6.06 Slope Function
6.06.01 2T Slope Function
(Set with internal parameter P19, Factory setting is P19 OFF)
This is the function to control the slope operation under 2T mode. It is necessary to set the upslope
time, down slope time, initial current and crater current. The current wave becomes as shown below
when this function is valid and invalid (OFF).
<2T Slope Function OFF> <2T Slope Function ON>

.
Internal parameter P19 to ON.
6.06.02 4TS Mode Setting
(Set with internal parameter P20, Factory setting is P20 OFF)
In the 4TS mode setting, when a torch switch is turned off during downslope, choose whether or not
to weld exiting from down slope to the crater current.
<4TS mode setting is OFF (P20 to OFF)> <4TS mode setting is ON (P20 to ON)>
