SPATZ+ Special Welding Machines

MATUSCHEK special welding machines are produced as independent machines adapted to specific customer requirements and as individual components for integration into existing customer systems or as a complete systems with integrated customer components. In conjunction with the weld timer technology of the SPATZ+ generation, the best possible access to movement and welding sequences is achieved, thus enabling consistently reproducible welding results. The ServoSPATZ+ control technology with which up to two servo axes can be controlled is used for the special welding machines.

SPATZ+ Projection Welding Machine

This special welding machine is equipped with 2 movable axes for turntables. Equipped with our Servo SPATZ + weld timer technology it results in a high quality system for integration at the customer production facilities.

When welding in the tool, several steps are brought into one system. The installation effort, space and, of course, investment costs can be reduced. The system is planned in close contact with us and tailored to the necessary requirements.

For Example: SPATZ+ Projection Welding Machine

The modular aluminium design makes the Alligator servo-projection welding machines extremely stable and free from torsion effects. At the same time, they weigh considerably less than comparable systems constructed from steel. Depending on the welding task, the system can be equipped with one driven servo axle and a fixed counter electrode or with two servo drive axles.

The welding current and the control of the servo-drives is provided for example by the ServoSPATZ+M600 power source. Combined with the built-in MFDC transformer (standard), this system configuration allows welding currents of up to 30 kA. Even more powerful system configurations are available on demand. Among other things, the projection geometry at the start of weld time defines the weld quality in projection welding applications. If this projection geometry is influenced in a negative way, due to rough approach of the welding electrode (frequently in pneumatically driven systems), effects on the strength of the welded joint are inevitable. The fast travel speed and the soft and controlled touch on the components are advantageous. The integrated measurement of electrode penetration provides data enabling functions such as part recognition and quality control.

Adjustable follow-up devices in the drive axles allow the optimal adaptation of electrode penetration during the weld process and reduce weld spatters. The equipment is, of course, also applicable for standard spot welding applications and is taking advantage of the adaptive MASTER control mode provided by ServoSPATZ power sources.
