SpotArc
The TIG SpotArc function is activated with the pulse variant automated frequencies by default, because
this combination produces the most effective results. The user can of course combine the function with
other pulse variants depending on the selected welding process.
NOTE
The up-slope and down-slope times should be set to “0 s” to achieve an effective result.
