14 Starting up
Make sure before turning-on, that
the electrode holder, electrode do
not touch on the welding table, the
working piece or any other object
which is conductive. Oth-erwise
an arc will be ignited accidentally.
An accidentally ignited arc can
damage the electrode holder, the
welding table, the working piece or
the machine.
