Single wire welding
In single wire welding, a signal is emitted by the robot controls, meaning that only one
power source welds.
Depending on the torch position or restricted position of the weld, 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, Standard, and CMT arcs are possible during single wire welding as
long as the appropriate Welding Package is available on the power source. It is not ne-
cessary to change the welding torch.
Single wire welding is used in a TWIN welding system:
-
When welding very tight radii
- When welding in difficult positions and restricted positions
- To fill up end-craters
- If there has been a switch to a single welding torch on the welding torch change sta-
