TECNA COLUMN-TYPE MEDIUM FREQUENCY SPOT WELDERS (6020F-6021F)

The TECNA column-type resistance welders with oscillating arm, medium frequency, and pneumatic system, series (6020F-6021F), offer a nominal power of 40kVA at 50% duty cycle in direct current.

The inverter technology significantly improves welding quality, providing extremely high precision in both time and current control. This not only increases productivity but also reduces costs, including connection costs, thanks to a better power factor.

The welding current is delivered continuously and consistently, ensuring excellent weld quality. The high precision of the current allows for homogeneous heating of the fusion zone, further improving the final result quality.

The millisecond adjustment allows for optimal welding time setup, while reducing the welding current used and balancing across the three phases leads to a significant reduction in energy consumption.

Improved welding times in spot welding operations on aluminum and coated sheets result in longer electrode life, reducing maintenance needs and thus increasing productivity. This inverter resistance welder is designed to produce high-quality welds.

The durable, heavy-duty copper-chrome electrode holder is suitable for heavy-duty applications and allows both straight and inclined mounting.

The epoxy resin welding transformer is water-cooled, as are the arms, electrodes, and electrode holder, contributing to more efficient and longer-lasting operation.

The TE751 microprocessor control unit comes with a USB port for data storage, ensuring easy and precise weld analysis.

The pneumatic cylinder operates without lubrication and without emitting oil mist, reducing maintenance costs. The filter-reducer group, with pressure gauge, is protected and easily accessible.

The two-stage electric foot control allows you to clamp the parts and weld them only if they are correctly positioned. Additionally, an extra electric foot pedal can be added to directly recall the second welding program, a feature particularly useful for performing different welds on the same piece.
