CHAPTER 1 – THE TE470/TE480 WELD CONTROL UNIT
The TE470/TE480 is a microprocessor-based weld control unit for suspended, single-phase resistance welding
guns. The task of this weld control unit is to manage the welder's components, especially the controlled diodes
that adjust the welding current. The special feature of this control unit is that it is fitted with specific functions,
when used with industrial welders, such as the double stroke control and the safeties efficiency check function
that, if installed, is present on the handle. The handle is not an integral part of the control unit since different
types of handles are used to adapt the machine to different work needs.
As many as 63 different weld programmes can be stored.
Depending on the type of handle connected to the control unit, from 2 to 4 programmes can be called from the
outside.
Each program consists of programmable parameters that describe the work cycle. In addition to the simple 4-
stroke cycle, the control unit enables the execution of welds with pre-weld, post-weld, slope and pulse current.
The TE470 can operate in conventional mode and constant current while the TE480 can work also in constant
energy mode.
Both control units display the welding current and envisage a control on the output current with settable limits.
