Button, Wire inching
For inching the wire electrode when changing the wire spool
(speed = 6.0 m/min, constant).
The welding wire is inched into the tube package with the current off and without gas
being expelled.
This ensures a high degree of safety for the welder by preventing accidental ignition of
the arc.
Button, Gas test
The welding voltage and wire feed remain off when testing and setting the gas flow.
Pressing the key button once causes shielding gas to flow for approx. 25 seconds. The
button can be pressed again at any time to cancel the process.
