Starting up Handy 180
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.
