Hotstart Function; Eln Function (Characteristic Selection) - Fronius TransPocket 4000 CEL Bedienungsanleitung

IMPORTANT! Parameters which can be adjusted on the TR 2000 / 3000 / 4000
remote control cannot be altered on the power source. These parameters can on-
ly be altered on the TR 2000 / 3000 / 4000 remote control.

All parameter set values that have been set by means of the adjusting dial (1) will
remain stored until the next time they are changed. This applies even if the power
source was switched off and on again in the interim.

Function
During the specified hot-current time (Hti), the welding current is increased to a
certain value. This value is 0-100% (HCU) higher than the selected welding cur-
rent (I
Example: A welding current (I
(HCU), a value of 50% has been selected. During the hot current time (Hti, e.g.
0.5 s), the actual welding current is 200 A + (50% of 200 A) = 300 A.

"con" parameter (constant welding voltage)
If the "con" parameter is set, the welding current will be kept constant, irrespec-
tive of the welding voltage. This results in a vertical characteristic (4).
The "con" parameter is especially suitable for rutile electrodes and basic electro-
des, as well as for arc air gouging. The "con" parameter is therefore also the fac-
tory setting when the "MMA welding" process is selected.
For arc air gouging, set the arc-force dynamic to "100".
