Parameter
Description
PRE-FLOW
This parameter operates in TIG modes only and is used to get gas to the weld zone
prior to striking the arc, once the torch trigger switch has been pressed. This control
is used to dramatically reduce weld porosity at the start of a weld.
HOT START
This parameter operates in all weld modes except Lift TIG mode and is used to heat
up the weld zone in TIG modes or improve the start characteristics for stick
electrodes. e.g. low hydrogen electrodes. It sets the peak start current on top of the
BASE (WELD)
current. e.g.
HOT START
current = 130 amps when
BASE (WELD)
=
100 amps &
HOT START
= 30 amps
INITIAL CUR.
This parameter operates in
SLOPE
or
REPEAT
(4T) TIG modes only and is used to
set the start current for TIG. The Start Current remains on until the torch trigger
switch is released after it has been depressed.
UP SLOPE
This parameter operates in TIG modes only and is used to set the time for the weld
current to ramp up, after the torch trigger switch has been pressed then released,
from INITIAL CUR to PEAK or BASE current
PEAK CUR.
This parameter sets the PEAK weld current when in
PULSE
mode
WELD
This parameter sets the TIG WELD current in
STD
,
SLOPE
,
REPEAT
and
SPOT
modes when
PULSE
is off. This parameter also sets the STICK weld current.
BASE
(Background
Current)
This parameter sets the Background current when in Pulse TIG mode.
SPOT TIME
This parameter sets the duration of the
SPOT TIME
in
HF TIG
mode only
PULSE
WIDTH
This parameter sets the percentage on time of the
PULSE FREQUENCY
for PEAK
weld current when the
PULSE
is on.
PULSE FREQ.
This parameter sets the
PULSE FREQUENCY
when the
PULSE
is on.
