"Wire inching" button
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.
"Gas test" button
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.
"Wire speed" signal light
Lights when the wire speed is shown on the display.
Current signal light
Lights when the current is shown on the display.
"Wire speed/welding parameter setting" rotary dial
Continuous adjustment of the wire speed or welding current and setting of runtime
parameters such as gas post-flows, wire burn-back, etc.
