TGX-M Manual Gun Manual gun with linear motor for drawn arc stud welding

The TGX-M manual gun is the logical evolution of the proven Tucker PLM560 manual gun for drawn arc stud welding. Ideal areas of use are prototype production at low volumes and rework stations. Nevertheless, the TGX-M gun offers absolute reliability and the best welding results; even with intensive continuous use. Compared to its predecessor, the TGX gun has been extensively revised and improved in key areas. From now on, the linear actuator with directly connected measuring system forms the core component of the TGX guns. This central system has been designed and intensively tested for repeatable, precise movements. Furthermore, new mouthpieces with outlets in combination with a seal reduce dirt accumulation due to the welding process. This manual version of the TGX series meets a wide range of requirements in terms of weld stud processability, base materials and surface finishes. AC welding (in combination with AC power source) and the use of shielding gas are also possible. Improved welding results in challenging steel applications as well as aluminum stud welding are mastered by the gun with excellence. The design of the TGX-M allows the user to adapt the gun to a wide range of stud geometries via a change of the frontend.

TUCKER CleanJet TH539 - Surface Cleaning For Perfect Aluminium Stud Welding

For aluminium stud welding, a clean surface of the workpiece is a basic requirement for a good welding result. Any kind of contamination such as dry lubricants or added oils added to during the part’s pressing process must be removed. Using Tucker CleanJet removes these surface contaminations with a specially designed plasma torch directly prior to the actual stud welding, making it a seamless process with no opportunity for re-contamination. This results in enhanced process stability, single-digit PPM, increased joint strength, less rework and less washing of components. Completely controllable and evaluable via the Tucker HMI (Human Machine Interface), industry-proven components were used and adapted to the needs of the automotive industry Tucker CleanJet TH539 - not only to achieve greater cost savings, but also leads to a more sustainable environment.
