TIG:
• HF CONSTANT
= HF on the entire
weld
•
HF START ONLY
= HF on only for the
start of the weld
• HF OFF = To
turn off, hold for 3
seconds
STICK:
• HS = Hot Start
• AF = Arc Force
TIG:
Controls High
Frequency settings;
HF can be set to
either Constant (on
the entire weld),
Start-Only (on for
only the beginning
of the weld), or off.
To turn HF off, hold
F3 for 3 seconds.
HF is particularly
useful for arc starts
to reduce tungsten
contamination, since
it is not required
to touch the work
piece while HF is
on. Default setting
for DC is START
ONLY. Default
setting for AC is
CONTINUOUS
STICK:
Hot Start increases amperage
when initiating the weld to
prevent sticking.
Arc Force changes the arc
characteristics from soft to
hard, which affects penetration
and bead profile.

PULSE
PPS % ON
• PEDAL/REMOTE
• PANEL/LOCAL
Activates Remote (foot pedal) or Local (panel) control.
While in Pedal/Remote, the foot pedal controls
the amperage. In Panel/Local, the user programs
amperage ramps and crater fill. A trigger torch or
standard torch can be used in this setting. Local is
beneficial for lift arc techniques as it provides more
amperage-related functionality. Note: Default setting
for STICK is Local. Function available only for TIG
welding.

PULSE
PPS % ON
• PULSE ON
• PULSE OFF
NOTE:
TIG functions only. Not available in
STICK.
Pulsing means the output amperage cycles between
Base Current and Main Current to provide more heat
control. Pulsing affects the bead profile and pattern.
Use MENU to step through PULSE options:
•
BASE CURRENT
–
changes the Base Current value.
Typically, Base Current is set to half of Main Current.
• PPS – changes how often amperage switches
between Base Current and Main Current per second.
A higher PPS setting creates focused puddle and tight
ripple bead pattern. A lower PPS creates broader
puddle and unique ripple bead pattern.
• % ON AT MAIN CURRENT – changes the
amount of time the pulse stays on at Main Current.
