 Use the proper wire tension. When welding with
mild steel or stainless steel, feed tension is
important but a little forgiving. Generally, the wire
tension should be set around 3. If that does not give
you good results, there is most likely a problem
unrelated to wire tension present. For example, a
bad contact tip, a bad liner, a defective welding
gun, etc. can cause wire to not feed smoothly.
When welding flux-cored wire, the tension should
be set lower than 2. If flux-cored wire is being fed
through a wire feeder with too much tension, the
tubular flux-cored wire will deform and its shape
will change; the wire will become oblong and too
big to fit through the contact tip. Improper
electrical contact, poor weld quality, burned tips,
and other issues will follow. Also, over-tightened
drive roll tension and deformed wire will cause
metal particles to separate from the wire. Those
particles will, over time (sometimes a very short
time, such as after welding only several pounds of
wire), deposit themselves in the liner as the wire is
transported through the gun, ultimately clogging
the liner and rendering it useless. When welding
aluminum, the drive roll tension should be less than
1. This minimizes the chances of the wire birds
nesting ( Note: If there is burn back or another issue
that jams the wire feed, the setting should be so
low that the drive rolls slip on the wire rather
than continue to feed, which results in birds
nesting ).

Use contact tips that match the diameter of the wire
selected. For example, use .030” contact tips
with .030” wire, use .035” contact tips with .035”
wire, and so on. Follow these instructions for all
wire types, no matter the metal or alloy. However,
on aluminum wire, we strongly recommend the use
of long-life contact tips or designated aluminum
contact tips (AL stamped into the tip next to the
size). If designated aluminum tips are not available,
and long-life tips are used, the tip size must
be .005” larger than the wire size. For example,
.035” aluminum wire would require the
standard .040” tip, and 3/64” aluminum wire would
require the standard .052” tip. ( Note: Designated
aluminum tips are manufactured roughly .005”
larger in actual diameter versus the same size
long-life tips, and .035” tips are used for .035”
wire .)

Use the correct polarity. Most MIG wires are
welded DCEP (electrode positive), and there are
very few exceptions to this rule (gasless flux-cored
wire and some specialty hard-surfacing wires are
exceptions). If in doubt, please consult the data
sheet that came with the wire, the box the wire
came in, or contact the distributor you bought the
wire from.

Use the correct welding gun. For welding stainless
steel wire or aluminum wire, a cylindrical gas
nozzle provides better gas coverage.
 If welding in synergic or pulse mode, select the
correct material thickness (reduce the material
thickness if you need to fill big gaps or if the
material you are welding is very hot) and observe
the wire manufacturer’s recommended CTWD.

Press and release Select Mode button A as many times
as needed until the green LED next to 2T illuminates.
If welding in the manual mode is desired, press and
release button B twice quickly. The machine is now in
manual mode ( Fig. 12 ). Turn encoder F to set the wire
feed speed, and turn encoder G to set the voltage.
If welding with synergic or pulse programs is desired,
press and release button B once to display the
program list ( Fig. 13 ).

Use encoder G to scroll through the program list, and
select the program that best fits your current job (the
yellow bar that highlights the program will move as
you turn encoder G ).
