4. The arc ignites for
a few hundredths of
a second (time can
be set up).
5. The result of this
is a very precise,
not oxidized weld
-
ing spot without any

○ Bring the torch up to the work until the electrode tip is approximately 2 or 3 mm away.
○
Press (1T) torch trigger.
○ The arc strikes without contact with the workpiece and the voltage discharges (HF) cease auto
-
matically.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ The welding procedure continues, at the preset current, for the time set with the spot time param
-
eter.
○ The current reaches the end current value in the time set in the down slope time parameter.
○ The arc is extinguished.
