1. Turn on the power switch on the rear of the unit. Allow unit to cycle through its start up program.
2. Select the Stick mode with the HF/Lift Start/Stick selector switch.
3. Make sure electrode holder is connected to the positive terminal and the work clamp is connected to the
negative connector. Make sure the connectors are twisted until light resistance is met.
4. Select the amps desired. Use the electrode diameter selection chart in this manual to determine the
approximate range of amps suitable for the rod size selected. Consult the welding electrode manufacturer’s
recommendation for proper amperage range. Each manufacturer has specific recommendations for its
electrodes. Usually these can be found on the packaging or on the respective manufacturer’s website.
5. Use the arc force control to select the desired arc characteristics, creating the desired arc characteristic
and
automatic amp response needed to maintain the arc when voltage falls below the threshold. 6011

electrodes may require more arc force control than other rods, but each brand and size will weld a
little differently. The arc force control setting will vary from person to person as well, with different rod
angles, positions,
and arc lengths all factoring into the arc force control performance. Set the arc start
intensity by adjusting the
“
start amps” knob to increase the hot start action and reduce rod sticking at the start
of the weld.
6. Strike the arc with either the tapping method or the match strike method. Beginners usually find that the
match strike method yields best results. Professionals tend to gravitate toward the tapping method because
of
its placement accuracy which helps prevent arc striking outside of the weld zone.
7. Terminate the arc by flipping the tip of the electrode up quickly with a quick flick of the wrist. Alternately,
pull directly back on the rod with a brisk, smooth motion.
IMPORTANT: Do not attempt to stick weld with the electrode holder while in the TIG Mode.
