Tweezer Welder

Some welding applications don't fit well in a weld head, or require more flexibility. Hand held welding attachments allow welding of complex geometries. Also hand held attachments are less expensive than weld heads. Welding attachments are easy to use, require low maintenance, and provide a lot of flexibility for small production runs or laboratory applications. Review the information below for technical data and images of the various hand pieces available.

How We Can Help You

About Us

Advanced Integrated Technologies is essentially a manufacturing service company with two major divisions. The resistance welding and reflow soldering tool division grew out of our early work building micro tools for Hughes Aircraft. About the time that Microsoft was turning computers into a household item, computer hardware manufacturers were looking for companies to build reflow tools used in the assembly of hard drives and other components.
