Welding parame-
ters in the TIG set-
up
"Minimum" and "maximum" are used for setting ranges that differ according to power
source, wire-feed unit, welding program, etc.
Spot welding time
Unit s
Setting range OFF / 0.05 - 25.0
Factory setting OFF
If a value has been set for the spot welding time, "2-step mode" will work in the same way
as spot welding mode.
The spot welding indicator remains lit on the control panel as long as a value has
been specified for the spot welding time.
Tacking function
for the TIG DC welding process: Duration of the pulsed welding current at the start of tack-
ing
Unit s
Setting range OFF / 0.1 - 9.9 / ON
Factory setting OFF
ON The pulsed welding current remains in effect until the end of the
tacking operation
0.1 - 9.9 s The set time begins with the upslope phase. After the end of the
pre-set time period, welding continues with a constant welding
current; any pulsing parameters that have been set are available.
OFF The tacking function is deactivated
The tacking indicator remains lit on the control panel as long as a value has been
specified for the tacking time.
Pulse frequency
Unit Hz / kHz
Setting range OFF / 0.20 Hz - 2.00 kHz
Factory setting OFF
The selected pulse frequency is also used for the reduced current I
2
.
IMPORTANT!If the pulse frequency is set to "OFF":
- then the welding parameters Duty Cycle, Ground Current and Wirefeed spd2 (from
cold wire setup) are not available
- the wire feed speed set on the control panel is used for constant wirefeed at a con-
stant welding current.
The pulse indicator remains lit on the control panel as long as a value has been spec-
ified for the pulse frequency.
Setting the pulse frequency:
0.2 Hz to 5 Hz Thermal pulsing (out-of-position welding, automated welding)
1 kHz to 2 kHz Arc-stabilising pulsing (stabilising the arc at a low welding cur-
rent)
