The TE470 is a microprocessor welding control unit designed specifically for suspended resistance welding guns. Its primary function is to control various components of the welder, with a particular focus on regulating the thyristors that adjust the welding current. This control unit offers specialized features for working with suspended welding guns, including double stroke control and the ability to monitor the effectiveness of safety devices installed on the machine’s handle.
It’s important to note that the handle is not included as a standard component of the welding control unit. However, the machine allows for the installation of different handles, allowing users to customize the settings based on specific performance requirements.
With a generous storage capacity, the TE470 can store up to 63 different welding programs. Users can directly recall two programs using an external selector typically installed on the handle, even when multiple handles are active. Each program consists of 19 adjustable parameters that describe the working cycle in detail.
In addition to the standard 4-times cycle, the control unit enables the execution of more advanced welding processes. This includes the ability to incorporate pre-weld current, post-weld current, slope, and pulses. The TE470 is capable of operating in constant current mode, providing a display of the welding current and monitoring it against the set limit for enhanced control and accuracy.
