Three-phase welding machines TECNA 6101, 6102, 6103, etc.

• Increased power factor;
• Reduced load on the power supply;
• Balanced load distribution between three phases;
• Reducing the influence of magnetic materials located between the arms on the characteristics of the welding current;
• Reducing the cost of installation work;
• Welding control units with direct output of the current value to the display;
• Six-phase rectifier on silicon diodes with a device for checking the reliability of the clamping contacts of diodes;
• Protection of diodes from exceeding the permissible voltage and temperature;
• Synchronous semiconductor contactor isolated from cooling water by a protective thermostat;
• Two-stage pedal control unit that provides clamping and welding of parts only if they are properly installed in the pliers;
• The possibility of installing an additional pedal control unit for calling program No. 2 (except for cars with a rotary program call switch);
• Emergency stop button for immediate shutdown of the machine;
• Protection by an automatic circuit breaker;
• Water-cooled transformer, plates, electrode holders and electrodes; transformer with epoxy coating of windings;
• Pneumatic cylinders with chrome-plated rods and gaskets with a reduced coefficient of friction that do not require lubrication. Adjustable double stroke cylinder controlled by a key, cylindrical guide rods with an adjustable device preventing rotation, prismatic precision roller guides;
• A complex cycle of operation of pneumatic devices with the possibility of applying a reduced compression force to the electrodes. Pressure change program on a separate order;
• Built-in filter and compressed air tank. Compressed air supply shut-off device;
• Lowering the electrodes without pressure for maintenance and adjustment;
• 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);
• The flow relay, which leads to the shutdown of the welding machine when the cooling water supply is stopped (works when water is supplied from a water pipe or an internal closed system).

• Stationary welding machines with three-phase direct current. Technical specifications.
