Resistance welding system controlled by a microprocessor, fully automatic, suitable for use in car body shop applications. The welding control unit uses a digital display with touch screen function and allows setting and monitoring all welding parameters according to the tools and according to the type and thickness of the sheets to be welded.
Briefly, the main features of this welding equipment can be summed up as follows: automatic identification of the connected welding gun; welding gun with integrated transformer enabling the connection to the welding system through an industrial socket and a set of quick fittings, thus allowing to avoid spanners, tools or screws for its replacement; welding gun main components i.e. transformer, arms, electrodes fully cooled by a closed loop cooling system, mounted on the cart of the system itself.
The welding transformer is fully designed and produced by TECNA. Integrated in the welding gun, it is fully water-cooled to optimize productivity and increase the duty cycle.
The water cooling system affects the transformer, the arms and the electrodes so to further increase the productivity of the equipment, through a heat exchanger.
The supporting arm includes a balancer produced by TECNA, designed and sized for a safe and comfortable operation in workshop environments.
New touch screen welding control unit with intuitive graphic diagrams, allowing a very simple use of the machine by the user. It is possible to choose between different operation modes: the automatic Smart+, Quick and Full mode.
The cart is ergonomic, compact and stable; it is provided with a proper armholder in the rear position.
New touch screen welding control unit with intuitive graphic diagrams, allowing a very simple use of the machine by the user.
It is possible to choose between different operation modes: the automatic Smart+ mode recognizes the thickness and type of material thus automatically determining the best values for current and force, the Quick mode requiring to set welding time, current and force only, and the Full mode which allows a personal setting of all the desired welding parameters.
A USB interface is available to easily export all data relevant to the performed welded spots for printing purposes. The same USB interface is used to update those welding parameters needed for new materials, parameters constantly developed by TECNA in cooperation with the main car manufacturers.

After listening to the requests and needs of our Customers and considering them a top priority for our R&D department, our engineers have developed a new clamping system, able to provide greater comfort and easiness of use of the machine.
The new push pull system consists of a patented mechanism that presents several important updates if compared with traditional Allen key or fixed external lever arm-opening systems:
