10. Wireline service indicator
Under normal working conditions, the WireLine service indicator is not visible. However, if
the welding gun contact tip or liner becomes dirty and blocked or the wire feed mechanism
needs routine maintenance or the friction plates in the spool brake need adjustment or
maintenance, the Spanner service symbol will illuminate indicating that maintenance is
required. Welding is not prevented when the WireLine service symbol is active.

1. dynamics control
Dynamics function controls the rate of rise of current when the filler wire is in short circuit
with the welding plate. This control adjustment is necessary due to the alternative welding
parameters, materials, wire sizes, gas types and current values used.
The welding dynamics scale is –9 to +9. Negative values make the rise of current slower, which
results in a hotter and more fluid weld characteristic. Positive values make the rise of current
faster, which results in a colder welding condition. This can result in more spatter during
welding depending on the filler wire size and type used.
