The Avio Opposed Weld Heads can be configured in a few different ways.  We offer two force ranges: 4.5 lbf – 33.7 lbf, and 9.0 lbf – 67.4 lbf.  (Note: if you want a lower force range, click here for our micro weld heads). 


Once you have determined the force range you require, the next step is to select the desired drive unit.  These heads can be configured with a manual foot pedal actuation, a pneumatic/air actuation, or a servo motor driven actuation.  Each drive unit offers unique advantages.  If you are unsure what configuration you need, please contact us and let one of our experienced micro welding consultants further discuss your welding needs.
