About Lampert
Lampert has been developing and producing fine welding machines based on micro-TIG welding (micro pulse welding) in Lower Franconia, Germany, for over 20 years. The product portfolio includes the PUK series for jewellery manufacturing (PUK 6.1), the PUK D6.1 specialized in dental prostheses and orthodontic appliances for dental laboratories, the Micro Arc Welder designed for laboratories, prototype construction and development departments, as well as the M280 model-making welding machine. With the FUSION tabletop casting centrifuge, the company also offers a solution for casting jewellery from old jewellery. The processes include micro pulse welding, brazing/soldering, repair and hermetic sealing welding of containers as well as electrical contacting at material thicknesses from 0.1 mm; weldable metals and alloys such as titanium, copper and precious metals are processed. The offering is complemented by training courses, tutorials, a showroom and a dealer network. The largely automated welding process is designed to enable simple, reproducible processes even for complex tasks.
