Arc-force dy-
namic To obtain optimum welding results, it will sometimes be necessary to adjust the
arc-force dynamic.
Setting range: 0 - 100 (corresponds to 0 - 200 A current increase)
Operating principle:
At the moment of droplet transfer or in the event of a short circuit, the amper-
age is briefly increased in order to obtain a stable arc.
If the rod electrode threatens to sink into the weld pool, this measure prevents
the weld pool solidifying, as well as preventing a prolonged short-circuit of the
arc. This largely prevents the rod electrode from sticking.
Setting the arc-force dynamic:
1
Press the setting value button until
the arc-force dynamic indicator lights up
2
Turn the adjusting dial until the desired correction value is reached
- Power source is ready for welding
NOTE!
The maximum arc-force dynamic current is limited to 180 A.
Examples:
- Arc-force dynamic = 0
- arc-force dynamic deactivated
- soft, low-spatter arc
- Arc-force dynamic = 20
- arc-force dynamic with 40 A current increase
- harder, more stable arc
- Set welding current = 100 A / arc-force dynamic = 60
- arc-force dynamic theoretically with 120 A current increase
- actual increase is just 80 A as the maximum current limit has been
reached!
