2. Unplug the feeder gas and cur-
rent cable/power plug and the
work cable from the welders
front panel.
3. Plug the FLEXTIG torch power
cable into the negative (-) weld
terminal and plug the work cable
into the positive (+) weld ter-
minal. This provides straight
polarity current as required for
TIG welding.
4. Plug the FLEXTIG torch switch
cord into the welder control
receptacle (OUTPUT).
5. Attach the FLEXTIG torch gas
hose directly to the gas regula-
tor/flowmeter and adjust the
flow to 20 C.F.H.
NOTE
Pure Argon is the shielding
gas to be used for TIG
welding.
