CW3 / CW4 Converter Welder


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 stationary tacks.

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 adjustable.

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 process.
