TE470 Welding Control Unit
The TE470 is a microprocessor welding control unit designed for suspended resistance welding guns. It plays a crucial role in controlling various parts of the welder, especially the thyristors responsible for adjusting the welding current. This control unit is specifically equipped with functions tailored for working with suspended welding guns. These functions include 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 a standard component of the welding control unit. Instead, different handles can be installed to customize the machine’s settings based on specific working requirements.
The TE470 has a generous storage capacity, allowing for the storage of up to 63 different welding programs. Additionally, it provides the capability to directly recall two programs using an external selector commonly installed on the handle. This feature is particularly useful when multiple active handles are present. Each welding program consists of 19 adjustable parameters that accurately describe the working cycle.
In addition to the standard 4-times cycle, the TE470 control unit enables the execution of welding processes involving pre-weld current, post-weld current, slope, and pulses. It can operate in constant current mode, providing a display of the welding current and monitoring it against the set limit.
