CHAPTER 1 – TE700 WELDING CONTROL UNIT DESCRIPTION
The TE700 is a microprocessor-based welding control unit for resistance welders equipped
with inverter technology. The task of the welding control unit is to manage the components of
the welder, specifically the IGBT power unit that adjusts the welding current.
The TE700 is a particularly versatile control unit since it can be adapted to different types of
welders. In addition to the spot and projection welders, it may also be installed on seam
welders and work with constant current, FIX, constant power, constant voltage, constant
energy adjustment and in dynamic mode. The number of the inputs and outputs may be
increased to better adapt the welding control unit to automatic machines.
The control unit can manage up to max 4 different welding transformers.
It is possible to store up to 300 different welding programs, 255 of which are recalled directly
from an external device. An alphanumeric identifier may be associated with each program to
simplify its identification. Each program comprises several programmable parameters that
describe the work cycle. In addition to the plain 4-stage welding cycle, the control unit allows
the running of welding processes with pre-welding current, post-welding current, slope and
pulses.

TECNA S.p.A. ITEM TE700 Instruction Manual
This RESTART button enables the control unit's commands and outputs. It must be pressed
every time the control unit is powered.
As soon as the RESTART command is issued, all the devices connected to the VAUX output
are supplied and the charging procedure for the capacitors bank is started on the inverter.
Before activating the RESTART command, it is important to check
that it will not cause damage to people or equipment.
The following message is displayed until the inverter is ready to weld.
INVERTER CAPACITOR
CHARGING PLEASE WAIT
Before starting any welding operations, first program the welding data and set some general
operating parameters of the welder.
For safety reasons, the microprocessor does not start the welding
cycle if the cycle start signal is actuated when the welder is turned
on. Simply release the control and actuate it again. Micro-cutoffs or
excessive voltage drops do not alter the control unit's working
efficiency but stop it. To restore working efficiency, turn off the
machine and then turn it on again.
