4.1.9.2 Torch mode setting
Modes 1 to 4 and 11 to 14 are available to the user. Modes 11 to 14 feature the same functionality as 1 to
4, but without the tapping function
> see 4.1.9.1 chapter
for the secondary current.
The functionality of the individual modes can be found in the corresponding torch type tables.
The torch modes are set using the torch configuration parameters "
" in the machine confi-
guration menu > torch mode "
"
> see 4.6 chapter
.
Only the modes listed are suitable for the corresponding torch types.
4.1.9.3 Up/down speed
The value set for up/down speed
determines the speed with which the current is changed. This func-
tion is possible (and useful) in torch modes 1
–4 and 11–14 only.
Press and hold the up push-button:
Increase current up to the maximum value (main current) set in the power source.
Press and hold the down push-button:
Decrease current to the minimum value.
The “up/down speed” parameter
is set in the machine configuration menu
> see 4.6 chapter
.
4.1.9.4 Current jump
This function is only available when using up/down torches in modes 4 and 14!
By tapping the corresponding torch trigger the welding current can be determined in an adjustable jump
range. Each tap will cause the welding current to jump up or down by the defined value.
The “current jump” parameter
is set in the machine configuration menu
> see 4.6 chapter
