ITASCA, IL – ITW has filed its 10-Q quarterly report showing third quarter operating revenues in its Power Systems and Electronics unit grew $53.3 million year-over-year, or 9.4%, to $620.7 million. Year to date, the segment is up 9.7% through Sept. 30.

For the quarter, the operating margin was 19%, down 50 basis points from a year ago. However, base margins climbed 40 basis points during the quarter. Base manufacturing revenues grew 3.1% and operating income was up 5%. Acquisitions made up another 3.7%, while currency translation costs added 2.5%. Growth was spurred primarily by a 26.4% jump in ITW’s international welding business.

The business unit includes Speedline Technologies, Vitronics-Soltec and Kester Solder, among others.
