The N550c Arc Charger™ is the first of a revolutionary new class of stud welding power sources developed around Nelson’s patent pending Arc Charger™ platform. The N550c Arc Charger™ has the capacity to weld the full range of drawn arc studs, up to 3/8” pitch (M8) diameter, with an ultra-smooth high-speed switching welding arc, while requiring power from just a standard household 120V wall outlet! This breakthrough combination enables high-strength drawn arc stud welding in just about any location, without the need for high voltage, industrial 3-phase power, or a large generator.

Nelson N550c Arc Charger Specifications:

• 120V input voltage
• 3A to 15A input current, user adjustable
• 60 Hz input line frequency
• Welds 6-3/8” pitch studs per minute
• Welds 15-3/16” studs per minute
• 3/8” pitch maximum diameter for steel, stainless steel, and aluminum studs
• 9 ft. (2.75 m) power cord
• 86 lbs. (39 kg)
• Standard 120VAC, 3-prong, grounded input power connection
• 25W maximum idle power
• Touch pad display with graphical diagnostics

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.

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.
