A tox machine, typically used for welding or brazing, permanently joins two parts together using electrical energy. The machine consists of several key components: a power supply (transformer, rectifier, or inverter for welding; induction or resistance heating systems for brazing), a welding/brazing head (torch, induction coil, or electrodes), a workpiece holder, a control system (PLCs or microcontrollers), a cooling system (water or air cooling), and safety mechanisms (emergency stop buttons, protective shields, and sensors). During operation, parts are cleaned and positioned in the fixture, parameters are set on the control system, and the machine delivers energy to create a permanent joint. The cooling system then solidifies the joint, which is inspected for quality assurance.

​

The operation begins with preparation, where parts are cleaned and positioned securely. The operator sets the necessary parameters, and the machine activates the welding or brazing head to melt and join the materials. For welding, a weld pool is created and solidified, while for brazing, a filler metal flows into the joint and bonds the parts. After the joining process, the cooling system ensures the joint is solidified safely. Finally, the joint is inspected for defects to ensure quality. These machines are widely used in industries such as automotive, aerospace, and construction, where strong and permanent joints are crucial.
