5.10.3.8 Latched/special-latched tap start (P9)

In latched – tap start – operating mode it is possible to switch straight to the second step by tapping the
torch trigger; it is not necessary for current to be flowing.
The welding can be halted by pressing the torch trigger for a second time.

5.10.3.9 "Single or dual operation" (P10) setting

If the system is fitted with two wire feeds, no further accessory components may be operated on
the 7-pole connection socket (digital)!
This relates to digital remote controls, robot interfaces, documentation interfaces, welding
torches with digital control lead connection, etc.
No second wire feed may be connected in single operation (P10 = 0)!
•
Remove connections to the second wire feed
In dual operation (P10 = 1 or 2), both wire feed units must be connected and configured differently
on the controls for this operating mode!
•
Configure one wire feed unit as the master (P10 = 1)
•
Configure the other wire feed unit as a slave (P10 = 2)
Wire feed units with key switches (optional, > see 5.9 chapter) must be configured as masters
(P10 = 1).
The wire feed configured as the master is active after the welding machine is switched on. There
are no other functional differences between the wire feeds.

5.10.3.10 Latched special tapping time setting (P11)

The tapping time for changing over between the main program and reduced main program can be set in
three levels.
0 = no tapping
1 = 320ms (factory setting)
2 = 640ms
