When the indicator lights up, F2 works
11. “JOB” No.
For receiving parameter records/job numbers that were previously saved with “Store” button.
12.Welding speed indicator
When the light is on, the right display shows the preset welding speed (cm/min) , and the wire speed and welding current
& voltage are calculated as a function of the “a”-dimension parameter (20)
13. Welding voltage indicator
When the indicator lights up, the right display shows the preset or actual welding voltage.
Important! Power source open circuit voltage is variable. In STICK mode, open circuit voltage displayed is about 23V
before welding; after starting arc, it increases as the real situation, and may be up to 79V, so as to get ideal arcing
characteristic.
14. Arc-length correction parameter
For correcting the arc length (-5.0-+5.0) by adjustment knob (1) when indicator is on, the right display shows the arc length
value when the indicator lights up.
- shorter arc length
0 neutral arc length
+ longer arc length
Important! The range (-5.0-+5.0) means that, when preset welding current, the arc length value is -50
％～
+50
％
of the
corresponding welding voltage.
15. Temperature Indicator
This is reserved function, cannot operate right now.
16. Arc force/ Arc stiffness
Change the arc stiffness during short circuit transition.
-The arc is hard and stable
0 Medium arc
+ Soft arc and small splash
17.
Wire feeding speed indicator
When the indicator is on, the left display shows the wire feeding speed (M/min), when adjust this button, the relevant
parameters will change automatically
18.Welding current indicator
When the indicator is on, the left display shows the preset or real welding current values
19.Sheet thickness indicator
When the indicator is on, the left display shows the preset sheet thickness (mm). The relevant parameters will change
automatically when this value is changed.
20. “a” dimension indicator
When the indicator is on, the left display shows “a” dimension (mm). Wire speed and welding current & voltage are
calculated as a function of the “a”-dimension parameter
21. F1 selection button indicator
When the indicator lights up, F1 button works.
22.CALL program mode indicator
When the indicator is on, power source is in call program mode.
23. Sub menu parameters regulation indicator
This indicator is on when in sub menu parameters adjustment.
4-4 Sub menu
Sub-menu parameter
In order to achieve an optimum welding result, it is necessary in some cases to make corrections of the arc-length, arc
force as well as parameters like pre-gas time, post-gas time and slow wire feeding. For details of how to set the Sub-menu
parameters, please refer to “Sub-menu parameter set”.
