Trigger Mode Selection:
[REMOTE STD] Remote Standard
Typically used with a remote foot or hand control. REMOTE STD requires
a maintained contact closure to enable weld output. Amperage can be con-
trolled with a remote potentiometer, or it can be set at the control panel.
[REMOTE HOLD] Remote Hold
Remote control required. Allows the operator to weld without holding the
trigger closed. To start the weld, operator presses and releases trigger. To
stop the weld, the operator again presses and releases the trigger. In this
mode, only the output contactor is controlled by the remote control. Amper-
age must be set on the control panel.
[PPS] Pulse Control:
Reduces heat input to minimize distortion and increase travel speed. Set
PPS (pulse per second). The range is OFF−150 PPS. Background Am-
perage and Peak Amperage are not adjustable. Background Amperage
equals 25% of Peak Amperage. Peak Amperage Time equals 40%.

Workpiece
Touch tungsten electrode to work-
piece, hold for 1-2 seconds, slowly
lift electrode, and an arc forms.
Open-circuit voltage maybe present
before electrode touches workpiece.
TIG Impulse
High frequency starts arc when output
is enabled without making contact with
the workpiece. High frequency turns
off when arc is started.
