Feeding in the wire electrode
Feeding in the
wire electrode
CAUTION! Risk of damage to the welding torch from sharp end of wire electro-
de. Deburr the end of the wire electrode well before feeding in.
CAUTION! Risk of injury from springiness of spooled wire electrode. When
inserting the wire electrode into the 4 roller drive, hold the end of the wire
electrode firmly to avoid injuries caused by the wire springing back.

Feeder inching / Gas test button
- Hold down the button for up to one
second ...For the first second, the
wire feed speed remains at 1 m/min
or 39.37 ipm.
- Hold down the button for up to 2.5
seconds ... After the end of a 1-
second period, the wire feed speed
increases at a uniform rate over the
next 1.5 seconds.
- Hold down the button for longer than
2.5 seconds ... After a total of 2.5
seconds the wire feed speed remains
constant at 10 m/min or 393.7 ipm.
Passage over time of the wire feed speed when the
feeder inching button is pressed and held down
Important! To facilitate exact positioning of the wire electrode, the following sequences
are possible when the feeder inching button is pressed and held down:
10
If the feeder inching button is released and pressed again before the end of the 1-
second period, the sequence starts again from the beginning. This makes it possible to
position the wire continuously at the low wire feed speed of 1 m/min or 39.37 ipm when
necessary.
