Ext. Parameter
External parameter
a user-defined welding parameter for the JobMaster TIG welding torch or robot interface
(both optional).
A freely selectable welding parameter is available both on the JobMaster TIG welding
torch and for the robot interface. If “Ext. parameter” has been selected, you can use the
adjusting dial to choose between the following possibilities for this freely definable weld-
ing parameter:
OFF No freely defined welding parameter has
been assigned (factory setting)
ELd Electrode diameter
bAL Balance
SPt Spot welding time
I-S Starting current
UPS UpSlope
I-2 Reduced current
dsl Downslope
I-E Final current
ACF AC frequency
F-P Pulse frequency
dcY Duty cycle
I-G Ground current
tAC Tacking function: Duration of
the tacking operation
Fd.1 Wire feed speed 1 (cold wire-
feed unit option)
The number of user-defined welding parameters depends on the configuration and the
mode that has been selected.
Special 2-step
Special 2-step mode for HF ignition after touching the workpiece
Unit -
Setting range OFF / 1
Factory setting OFF
Ignition sequence, when the STS parameter is set to 1:
- Touch the workpiece with the tungsten electrode
- The short-circuit detection on the power source is triggered
- Lift the tungsten electrode off
- After 300 ms the gas pre-flow time begins
- HF ignition is initiated
- Welding ends due to arc break
Ign. delay
Ignition delay
Delayed ignition with immediate high frequency start
Unit s
Setting range OFF / 0.1 - 1
Factory setting OFF
If a time value is set for the welding parameter "Ign. delay", the welding arc is ignited with
a delay according to this time value: Press the torch trigger - high frequency is activated
for the specified duration - the welding arc is ignited
