Single-point ground welding machine handles wire bundles of up to 0.79 sq. in.
Sonobond Ultrasonics has developed the SPG 2600 ultrasonic spot welding machine for manufacturing single-point ground terminals, which help solve the problem of electrical noise caused by today's intricate automobile systems.
The unit's tooling is designed to gather as many as 18 wires into a single terminal. Once the weld has been made, a set of clamps automatically completes the assembly by folding over the terminal's arms to provide stress relief on the joint. The unit can handle wire bundles of up to 0.79 sq. in.
The machine's power supply features a built-in microprocessor that can store and recall up to 250 weld protocols from memory. A digital display allows selection of welding modes by time or energy and provides automatic frequency control and overload protection. An RS-232 port transfers weld data to or from a computer. It also uses automatic control monitoring that can detect when variables exceed preset power and time limits.
