Arc-Force Dynamic - Fronius TransPocket 150 Operating Instructions Manual

Example of HotStart function
Arc-force To obtain optimum welding results, it will sometimes be necessary to adjust the arc-force
dynamic 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 amperage 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.

TransPocket 150 to 180 A
TransPocket 180 to 220 A

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
Arc-force dynamic = 60, set welding current = 100 A
• for the TransPocket 150: actual increase is just 80 A as the maximum current
limit is reached!
• for the TransPocket 180: arc-force dynamic with 120 A current increase
Features of SoftStart function:
- Reduced pore formation with certain
electrode types
Features of HotStart function:
- Improved ignition properties, even
when using electrodes with poor igni-
tion properties
- Better fusion of the base material dur-
ing the start-up phase, meaning fewer
cold-shut defects
- Largely prevents slag inclusions
