(26) Welding current indicator ... for
selecting the welding amperage.
Before the start of welding, the
machine automatically displays a
guideline value based on the pro-
grammed parameters. During wel-
ding, the actual value is displayed.
(27) HOLD indicator ... every time you
finish a welding operation, the actual
values for welding current and volta-
ge are stored, and the “Hold” indica-
tor lights up.
(28) Welding-current setting dial ... for
selecting the welding current .

(29) Process selector switch ... for
selecting the welding process
- Rod electrode welding
- Rod electrode welding with CEL-
electrode

ignition
(30) Welding-current range selector switch for selecting the welding-current range
within which the welding current can be set using the welding-current setting
