TIG welding is selected. The required welding current is obtained from the analog „Wel-
ding current" input signal.

Gas test

Signal X2:7
The "Gas test" signal starts the "Gas test" function (as does the "Gas test" key). The
required gas flow can be set on the pressure regulator on the gas cylinder.
The gas test can be used to create an additional gas pre-flow during positioning.
IMPORTANT! If welding is in progress, the gas pre-flow and post-flow times are control-
led by the power source. It is therefore not necessary to set the "Gas test" signal when
welding!
Use the "Robot ready" input signal to set up the power source for welding
Use the "Welding current" input signal to specify the required welding current
Use the "External parameter 1" input signal to enter a value that the welding voltage
is not to exceed.
IMPORTANT! If no maximum welding voltage is required, use the "External Parame-
ter 1" input signal to specify the highest possible welding voltage.
Should a voltage occur that is higher than the specified welding voltage, it will not be
possible to maintain the selected welding current.
Set the required wirefeed speed using the "Base current" input signal
Use the "Welding start" input signal to start the welding current
Start the wire feed with the "Wire feed" input signal
Use the "Robot ready" input signal to set up the power source for welding
Use the "External parameter 1" input signal to enter the required welding voltage
Use the "Welding current" input signal to enter a value that the welding current is not
to exceed.
NOTE! If no maximum welding current is required, use the "Welding current" input
signal to specify the highest possible welding current.
Should a current occur that is higher than the specified welding current, it will not be
possible to maintain the selected welding voltage.
Set the required wirefeed speed using the "Base current" input signal
Use the "Welding start" input signal to start the welding current
Start the wire feed with the "Wire feed" input signal
