4. OPERATION AND DESCRIPTION
1. Current knob: Welding current, arc-force current and hot
start arc igniting current can be adjusted from low to high by
rotating the knob clockwise.
2 : It is MMA mode where electrode diameter cannot be
adjusted but arc-force and hot start can be adjusted with
indicator on.
3. “SYN”: It is MMA synergic mode where the hot start
current and arc-force current are selected automatically by
program after specified electrode is selected with indicator
on.
4. : It is lift TIG welding mode with indicator on.
5. : MMA synergic electrode diameter
selecting indicator. When the triangular symbol is on, the
corresponding diameter is selected.
Hot start current and arc-force current are selected
automatically by program at this time.
6.“A”: MMA welding current status indicator. When it is
blinking, MMA welding current can be set at present.
7. : MMA arc-force adjusting indicator. When it is blinking,
arc-force current can be set at present.
8. : MMA hot start adjusting indicator. When it is blinking,
hot start current can be set at present.
9. : It is welding status and current setting
indicator which is scrolling displaying during welding.
10. LED digital display：
① ， LED digital tube displays current value which is set
currently;
② ， It displays setting value of arc-force when arc-force
indicator is blinking;
③，It displays setting value of hot start;
④，It displays E60 when machine is under overheat protection
and stops working until E60 disappears;
⑤ ， It displays E13 when machine is under over-current
protection which means internal components are damaged,
please contact dealer for help.
