Single wire welding
In single wire welding, a signal is emitted by the robot controls, meaning that only one pow-
er source welds.
Depending on the torch position or restricted position of the weld seam, the single wire
welding can be carried out by the lead or trail power source. The second power source
pauses.
NOTE!
In order to ensure a full gas shield during single wire welding with TWIN welding
torches, the solenoid valve for the pausing power source is open.
The solenoid valve is controlled via the power source.
PMC, Pulse, LSC and Standard arcs are possible during single wire welding as long as the
appropriate welding package is available on the power source. It is not necessary to
change the welding torch.
