Bench spot and projection welders (2101D-2144D e 2102N)

The spot and projection bench resistance welders (2101D-2144D and 2102N) are designed to offer high performance and operational flexibility across a wide range of industrial applications. The nominal power at 50% in direct current ranges from 16kVA to 150kVA, making them suitable for both light-duty work on small components and more robust assemblies.

All machines, except for the model (2101N), are equipped with a microprocessor control with direct reading of the welding current, a key feature to ensure reliability, repeatability, and process control. The cylinder and rod are made of thick chrome-plated steel, a construction choice ideal for heavy-duty environments requiring long service life and mechanical resistance. The adjustable anti-rotation device ensures precision and stability during every welding cycle.

Another strength of these machines is the use of pneumatic components that do not require lubrication, thus eliminating the emission of oil mist and helping to maintain a cleaner and safer working environment. Models (2121D-2144D) are equipped with a double-stroke cylinder and key switch control, allowing advanced adjustment of welding parameters.

Each machine includes a built-in compressed air filter-regulator unit and a shut-off valve for air supply, ensuring continuity and efficiency in airflow management. The two-stage electric foot pedal allows the piece to be clamped and the welding process to start only when conditions are optimal, improving weld quality and reducing the risk of errors. There is also provision for connecting a second two-stage electric foot pedal, with direct recall of welding program no. 2, except for models (2101D-2102N-2103D) and versions equipped with options (2161) and (2181).

The welding transformer, plates, electrode holders, and copper alloy electrodes are water-cooled, while the windings are resin-encapsulated for added protection and greater long-term reliability. The synchronous control with SCR is isolated from the cooling circuit and protected by a thermostat, ensuring safe operation even in the most demanding conditions.

All models, except for (2102N), are equipped as standard with a two-hand control with safety timer and removable key selector to prevent accidental or unauthorized activation. The dual-control is standard in projection welding versions and available upon request for spot welders. Models (2101D-2103D-2144D) are prepared for dual-control connection, thus offering additional options for customizing the work cycle.
