Desktop machines TECNA 2121, 2122, 2123, 2124, 2101, etc.

• Microprocessor control unit with direct output of welding current to the display (except 2102);
• Cylinder with chrome-plated stem for heavy duty, designed for a long service life, with an adjustable device that prevents rotation;
• The elements of the pneumatic system do not require lubrication, which prevents the appearance of oil mist and environmental pollution;
• Adjustable double stroke cylinder, key operated;
• Built-in filter system with compressed air pressure adjustment device and compressed air supply shut-off device;
• Electrode feed rate control valves with vibration dampener at the end of the stroke and silencers at the air outlets, which ensures a minimum noise level;
• Two-stage pedal control unit that provides clamping and welding of parts only if they are properly installed in the pincers;
• Pre-setting of the operation parameters of the two-stage pedal control unit for direct calling of the programmed welding cycle No. 2 (except for products equipped with option 2161-2181);
• Water-cooled transformer, plates, electrode holders and electrodes; transformer with epoxy coating of windings;
• Synchronous semiconductor contactor isolated from cooling water by a protective thermostat;
• On all models: two-handed protective control unit with timer and removable switch key, ensuring maximum safety. The two-handed protective control unit is included as standard only for relief welding machines (it is installed on spot welding machines on a separate order).
