Miyachi’s fine spot weld heads excel in providing consistent, precise, high quality welds at low pressures. Their variable pressure settings range from 4 oz. up to 150 lbs. and their low inertia design, coupled with their force firing system, ensures a quick dynamic response that initiates the weld control at the precise moment when the preset electrode force is applied to the workpiece.

Miyachi’s fine spot weld heads are designed for either in-line or series welding. For automated applications, they can be used with an air actuation system for repeatable, reliable high speed operation.

The variety of fine spot weld heads allows for their use with a wide range of welding applications. Typical applications include battery pack assembly, small Electro-mechanical parts, miniature lamps, switch contacts, electrical connectors, and terminal connections. Whatever your application, the high performance and durability of these welders will deliver the high quality, precision small parts welding capabilities you require.
