REAR CONTROL PANEL

1. Power Switch: Controls the input power to the
machine. Make sure the machine is properly con-
nected to the input supply before turning the
machine on.(See Figure B.1)
2. Fan: The cooling fan will turn ON when the machine
is turned ON and it will continue to run whenever the
output of the machine is ON. If the output of the
machine is OFF for more than five minutes, the fan
will turn OFF. This reduces the amount of dirt that is
deposited inside the machine and reduces power
consumption.(See Figure B.1)
Refer to the Output LED section below for more infor-
mation about conditions when the output of the
machine is ON. (See Figure B.1)
CONTROLS AND SETTINGS (See Figure B.2)
3. Mode Switch: This switch changes the welding
modes of the machine. The V160-S has two welding
modes: Stick (SMAW) and Lift TIG (GTAW).
When the mode switch is in the Lift TIG position, the
stick welding functions are disabled and the machine is
ready for Lift TIG welding. Lift TIG is a method of start-
ing a TIG weld by first pressing the TIG torch electrode
on the work piece in order to create a low current short
circuit. Then, the electrode is lifted from the work piece
to start the TIG arc.

4. Arc Control: The Arc Control simultaneously adjust the
level at Hot Start and Arc Force. Increasing the Arc
Control setting increases both Hot Start and Arc Force.
• Hot Start: This is a temporary increase in the output
current during the start of the stick welding process.
This helps ignite the arc quickly and reliably.
• Arc Force: This is a temporary increase in the output
current during normal stick welding. This temporary
increase in output current is used to clear intermit-
tent shorts between the electrode and the weld pud-
dle that occur during normal stick welding.
5. Power LED: This indicator will blink on and off when
the machine is first turned on. After approximately 2
seconds it will stop blinking and remain on to signal
that the machine is ready. The indicator will also
blink during over current conditions when operating
on 115V input.
6. Thermal LED: This indicator will turn on when the
machine is overheated and the output has been dis-
abled. This normally occurs when the duty cycle of the
machine has been exceeded. Leave the machine on to
allow the internal components to cool. When the indi-
cator turns off, normal operation is again possible.
