The ATI CW3 Converter Welder removes all the aggravation,
eliminates all the guesswork and produces a perfectly
true, leak-proof converter far superior to OEM quality—one
that you will be proud to sell and confident to use!
The CW3 has complete tack speed control, and allows for
“rolling” tacks—which are completely
covered by the final weld bead. This makes for a better
quality weld, and eliminates the leaks that come from
Some welding machines attempt to defy gravity by requiring
the weld to be above the torch. ATI’s proven CW3
rotates 90° so the operator can always weld with the
torch facing down, which allows the bead to “lay
in” properly. The CW3 positions the converter at
a 45° angle, which makes for an ideal weld.
The rotational speed of the converter as it’s being
welded is crucial. Different converters require different
weld speeds—and that’s why the CW3 offers
five selectable speed settings, with each of them independently
Converter-to-converter consistency is assured through
the CW3’s use of a 6-jaw chuck instead of a collet.
GM engineers have confirmed that this is the only method
they know of that will provide repeatability in the welding
and weld torque converters in 2 minutes or less.
