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.
3
Press the "Parameter selection" button (2) (indicator on the button must light
up)
4
Set the desired amperage using the adjusting dial (1) (value can be read off
from the left-hand indicator)
5
Press the "Parameter selection" button (2) (indicator on the button must light
up)
6
Set the desired arc-force dynamic using the adjusting dial (1) (value can be
read off from the left-hand indicator)
7
Start welding
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.
HotStart func-
tion To obtain optimum welding results, it will sometimes be necessary to adjust the
HotStart function.
Advantages
- Improved ignition properties, even when using electrodes with poor ignition
properties
- Better fusion of the base material in the start-up phase, meaning fewer cold-
shut defects
- Largely prevents slag inclusions
For details on setting the available parameters, please see the section headed
"Setup menu: level 1".
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
H
).
Example: A welding current (I
H
) of 200 A has been set. For the hot current time
(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.
Eln function
(characteristic
selection)
The Eln function can be configured separately for the processes "MMA welding",
"MMA welding with Cel electrode" and "Special processes".
Note! For details on setting the available parameters, please see the section hea-
ded "Setup menu: level 1".
"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".
