INSTALLATION
EXPOSURE TO A WELDING ARC IS
EXTREMELY HARMFUL TO THE EYES
AND SKIN! Prolonged exposure to the
welding arc can cause blindness and
burns. Never strike an arc or begin
welding until you are adequately
protected. Wear flame-proof welding
gloves, a heavy long sleeved shirt,
trousers without cuffs, high topped
shoes, and an ANSI approved welding
helmet.
1. INSTALLATION OF TIG TORCH
1.1 Remove Ground Cable and install in the 35-
70 dinse connection. This sets up the TIG torch
for DC Electrode Negative which is needed for
DC TIG welding of steels and stainless steels.
1.2 Secure the ground clamp to the surface you
are welding.
1.3 Connect your regulator and gas hose to the
bottle of shielding gas. Typically 100% argon is
used for most TIG applications. Connect the TIG
torch gas connection to the regulator.
1.4 Connect the TIG torch weld power
connector to the negative (-) connection. This
sets up the TIG torch for DC Electrode Negative
which is needed for DC TIG welding of steels
and stainless steels.
1.5 Move the process selector switch on your
welder into stick mode. This puts the machine
into the constant current mode needed for TIG
welding.
Be aware that the TIG torch is now electrically
hot. Keep TIG torch away from the grounded
work surface until ready to weld.
1.6 Set Amperage on the front of the welder.
1.7 Turn on the input power switch on your
welder.
Be aware that the TIG torch is now electrically
hot. Keep TIG torch away from the grounded
work surface until ready to weld.
1.8 Turn the TIG Torch gas valve clockwise to
start the flow of shielding gas. After welding, turn
the TIG torch gas valve counter-clockwise to
turn off the flow of shielding gas.
1.9 Touch tungsten to work piece and lift away
to start arc.
DC TIG OPERATION
EXPOSURE TO A WELDING ARC IS
EXTREMELY HARMFUL TO THE EYES
AND SKIN! Prolonged exposure to the

protected. Wear flame-proof welding

Be aware that the TIG torch will be
electrically HOT when the Input Power
Switch on the welder is turned on.
1. Remove the ground cable and the
electrode holder from the weld output
connections. Install the ground cable to the
Positive (+) weld output connection.
2. Secure the ground clamp to the work
piece
