Short circuit
Current-rise (short circuit)
The parameter [A/ms] describes how the current is ramped up in the event of a short circuit.
End of welding
Guideline values
Guideline value for material
The guideline value for the material strength [mm] is normally determined by trial and error
or by performing a test weld
Voltage guideline value
The voltage guideline value [V] is normally determined by trial and error or by performing
a test weld. On power sources TS 4000/5000 and TPS 2700/4000/5000, the voltage guide-
line value corresponds to the voltage on the contact tube.
Current guideline value
In MIG/MAG standard manual welding, the current guideline value [A] is normally deter-
mined by trial and error or by performing a test weld.
Accepting volt-
age and current
guideline values
Voltage and current guideline values are accepted by the remote control unit directly from
the test weld:
Voltage and current guideline values during test weld,
continuous black selection bar
Set welding voltage and welding cur-
rent at the power source
Perform test weld
–
During the welding process, the
present values for welding voltage
and welding current appear as ac-
tual values on the remote control
unit. The values cannot be altered
during the welding process; the
selection bar appears completely
black.
At the end of welding, the last active
hold values for welding voltage and
welding current are accepted as volta-
ge and current guideline values. Volta-
ge and current guideline values can be
kept or reset.
Burn-back time
The burn-back time [s] can be saved for each characteristic point.
0.00
=
minimum burn back time (risk of wire sticking to weld pool)
0.40
=
maximum burn back time (risk of wire sticking to contact tube)
