TECNA’s 3664P 14000Amp Automatic Spot Welder from Italy, with “SMART PLUS” technology is a revolution in automotive spot welding equipment. It has sophisticated and upgradable software that is designed to take the guess work out of entering parameters such as metal type, number of panels and panel thickness to perform the correct spot welds. At the push of a button, the machine automatically detects and measures the metal panels and applies the exact amount of welding current, welding time and clamping force to consistently produce factory quality spot welds on steel, HSS, UHSS and Boron without any operator input!

OEMs invest a considerable amount of time and money evaluating and testing equipment for approval. When an OEM approves a welder it is confirming that the welder is capable of performing quality welds equivalent to those performed on the assembly line. OEMs take into consideration not only welding performance, but also availability and after sales technical support. TECNA is the only spot welder brand that manufactures welders for the assembly line as well as for the collision repair shop. TECNA is in a unique position to transfer the technology developed for and on the assembly line to the collision repair environment.

The TECNA 14000 Automatic is one of the most OEM approved spot welders on the market, with more ongoing. In fact, large car manufacturers use the TECNA 14000 Automatic as an end of assembly line spot welder. See below:
