peak of current to apply; that value is enough to breaks the metal drop that is being transferred from
the electrode to the workpiece as to guarantee the arc stability, but not too high to avoid spatters
around the welding puddle. That means:

Electrode / workpiece sticking prevention, also with low current values.

Spatters reduction.
Hot Start: This is a temporary increase in the initial welding current. This helps to ignite the arc
quickly and reliably.
Anti-NDicking: This is a function that decreases the output current of the machine to a low level
when the operator makes an error and sticks the electrode to the work piece. This decrease in
current allows the operator to remove the electrode from the electrode holder without creating large
sparks that can damage electrode holder
Maintenance
For any maintenance or repair operations it is recommended to contact the nearest technical
service center or Lincoln Electric Bester Sp. z o.o.
unauthorized service centers or personnel will null and void the manufacturers warranty.
Mains supply network must be disconnected from the machine before each maintenance and
