Single Point Ground Welder

Sonobond Ultrasonics' new Single Point Ground Welder SPG 2600 is for use in manufacturing single point ground terminals. The tooling is designed for gathering 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 20 square mm.

The unit'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. The Single Point Ground Welder has an RS232 port for transferring weld data to or from a computer and utilizes automatic control monitoring that can detect when variables exceed preset power and time limits.

The unit features heat-treated, tool steel Taper Lock Tips that can last up to 100,000 welds and are designed for fast removal and replacement. Ultrasonic metal welding creates solid-state metallurgical bonds without heat, current, fluxes or fillers and there are no costs for consumables or post-assembly cleaning.

The Single Point Ground Welder SPG 2600 uses Sonobond's Wedge-Reed coupling system to combine high vibratory force with low amplitude coupling. High-frequency ultrasonic energy is directed to the surface between the metals to be welded. This is done via the unit's welding tip. The applied vibratory energy disperses the oxides and surface films between the work pieces. A metallurgical bond is accomplished in one step without arcs, sparks or fumes and without melting the materials. It can handle lightly tinned or oxidized wires.
