to break the contact during at least ½ second,
then make a new contact.

DETECTION TIME
In this unit it is possible to choose betwe-
en two time options for the detection of the
shortcircuit (time from the contact of the gun
with the workpiece to the welding point ge-
neration). The selected option is shown by
a point on the left bottom side of the Mode
Dispaly (1).
Point ON = long time
Point OFF = short time
• In automatic mode, set “0” on the display
(1) with the Mode key (10), press the key (12)
to set the short or long time for automatic wel-
ding.

The machine keeps in memory the last se-
lected time option.
