8.1 Threading
The threading function is used to thread the welding wire into the torch hose set
without current. The welding wire is threaded into the torch hose set by means of
the push button above the feed unit (Fig. 4). By pressing the pushbutton
"Threading", threading is carried out for 2 seconds at reduced speed. The
threading speed is then increased over a period of approx. 2 seconds to the set
threading speed.

8.2 Gas
test
The "gas test" is used to set the required gas quantity at the pressure reducer.
This enables the desired gas flow to be set without wire feeding and voltage.
A push button for the gas test is located above the feed unit (Fig. 4). When the
push button is pressed, the gas valve is opened and inert gas flows out of the
welding torch.
The gas test is automatically terminated after 20 seconds. The gas test can be
aborted prematurely by pressing the "Gas test" button or the torch button.
