S100 Stinger™ Spot Bonder

S100 Stinger™ Spot Bonder

This specialized tool combines an extremely fast spot-bonding rate with enhanced safety and portability features. Over the last 30 years, BDI has installed tens of thousands of weldable foil strain gages around the world. Based on this extensive experience, we’ve developed the new S100 Stinger™, rapid capacitive discharge bonder for spot bonding weldable strain gages. Similar to all BDI instruments, the S100 Stinger™ is rugged, efficient, and reliable in all types of adverse field conditions.

Capable of up to 60 bonds per minute, and 1200 bonds per charge on a quickly replaceable battery, you will be amazed at how fast and accurate your strain gage installations can be completed.
