From micro to macro welding Compared to low process frequencies, the higher process frequencies allow for even more adjustment options to apply the energy required for the welding process metered and targeted. This leads to higher quality and an extended range of welding applications. 100% protection from power fluctuations The standard active power supply module offers protection from power fluctuations. The active power supply module provides a separate supply voltage for the inverter independent of the mains voltage. This means the inverter supply is independent of mains voltage drops...

Welding system overview Energy efficiency The active power supply module for the welding voltage reduces the grid load by up to 50%, since the energy required for welding is provided by a separate voltage supply. Control and monitoring Each measuring channel can be combined with limits and/or control and monitoring functions to guarantee optimum process control. Optional integration of servo axes Ability to upgrade with servo axes for welding tool movement. This allows for an independent, flexible and optimum integration of movements in the welding process. Optimum process control Choice of...

Version 1: B 20K Stand-alone with touchscreen operation and keyboard on the control cabinet. The standard version includes 2 welding positions. Extensions with a maximum of 8 welding positions are possible with additional cabinets. This version provides compatibility with the B 1000 and B 5000 welding control systems. Input and output functions are possible without programming. The variety of applications for the stand-alone version ranges from integration in production and manufacturing systems to replacing existing B 1000 and B 5000 welding control systems. 1 inverter for all transformer...

Welding system details Welding profile With simple menu navigation, preconfigured selection fields and graphical visualization, welding profiles can be created and customized easily and quickly. Up to 25 different welding profiles can be used for each tool / welding task. Assignment of the corresponding welding profile is performed with the B 20K control functions. If several welds are performed with one welding station, there are different boundary conditions for each weld (such as different initial temperatures). For each boundary condition, a separate welding profile can be selected....

B 20K New perspectives for press and progressive technology

Welding system details Open-loop and closed-loop control modes Profile control with individually programmed welding profile Stepper function for automatic current and output correction The created welding profile is used as setpoint curve. The welding profile can be based on the current profile [A] or the output profile [P]. With the stepper function, current or output values can be increased step-by-step or continuously when the number of welds increases. In step mode, the increase after each individual weld exactly follows a defined parameter value. In continuous mode, the increase is by...

Welding system details Process monitoring The B 20K provides various process monitoring functions and options. For each of the 5 measuring channels, the entire measuring curve as well as individual values in the curve can be monitored and used for different actions and reactions. This means rejected welds can be safely identified. Universal process monitoring with envelope A tolerance band is automatically generated across the entire measuring curve of a reference weld (good part). The size of the tolerance band (+-) can be defined freely. Each measuring curve of successive welds is...
