Function description
35

Special parameter SP6
–
Voltage indicator
0 Voltage indicator off
1
Average voltage is shown at the end of every weld.
2 The actual voltage is shown when welding (the value is updated every 2
seconds) and at the end of every weld.
Voltage detection range:

Special parameter SO7
–
Adjustment speed Up/Down torch
Setting the welding current I
1
or I
2
adjustment speed using the up/down torch
trigger.
Value range:
0 (slow) to 7 (fast)
Note
This special parameter is active when special parameter 2
“up/down torch” is
set to 1.

Special parameter factory setting CLr
When CLr is selected the digital display flashes. All parameters are reset to
the factory settings. Programs 1 to 99 and the special parameters remain.
