LT-050B-A/24 Light Force Pneumatic Weld Head – Parallel Gap Electrodes

Formerly known as 50A, 50A/24

The LT-050B-A/24 Light Force Micro Welding Head is an air actuated, precision, low inertia head designed specifically for delicate, parallel gap welding. True vertical electrode motion eliminates electrode wiping action. Built in the USA, with a low mass spring and compound lever force system ensures accurate, repeatable welding force in the 40 to 1,000 gram range making LT-050B-A/24 perfect for wire and ribbon applications such as fine trace circuit board repair, wire wound potentiometers, hybrid microwave devices, pacemakers, electrical fuses, ordnance fuses, smart cards and solar cells.

  • Very Low Force – 40 to 1,000 grams
  • True vertical electrode force motion
  • Exclusive “Unitip” electrodes
  • Specifically designed for microwelding applications
